Slavery in the United States was the legal institution of human chattel enslavement, primarily of Africans and African Americans, that existed in the United States of America from the beginning of the nation until passage of the Thirteenth Amendment in 1865. Slavery had been practiced in British America from early colonial days, and was legal in all thirteen colonies at the time those colonies formed the United States. Under the law, an enslaved person was treated as property and could be bought, sold, or given away. Slavery lasted in about half of U.S. states until 1865. As an economic system, slavery was largely replaced by sharecropping and convict leasing.
By the time of the American Revolution (1775–1783), the status of enslaved people had been institutionalized as a racial caste associated with African ancestry. The role of slavery under the U.S. Constitution (1789) was the most contentious issue during its drafting. Although the creators of the Constitution never used the word "slavery", the final document, through the three-fifths clause, gave slave-owners disproportionate political power. During and immediately following the War, abolitionist laws were passed in most Northern states and a movement developed to abolish slavery. All Northern states had abolished slavery in some way by 1805; sometimes, abolition was a gradual process, and hundreds of people were still enslaved in the Northern states as late as the 1840 Census. Some slaveowners—primarily in the Upper South—freed the people they had enslaved, and philanthropists and charitable groups bought and freed other enslaved people. The Atlantic slave trade was outlawed by individual states beginning during the American Revolution. The import-trade was banned by Congress in 1808, although smuggling was common thereafter.:7
The rapid expansion of the cotton industry in the Deep South after the invention of the cotton gin greatly increased demand for the labor of enslaved people, and the Southern states continued as slave societies. Those states attempted to extend slavery into the new western territories to keep their share of political power in the nation. The United States became ever more polarized over the issue of slavery, split into slave and free states. Driven by labor demands from new cotton plantations in the Deep South, the northern slave states sold over a million enslaved people who were taken to the Deep South in a forced migration. The total population of enslaved people in the South eventually reached four million. As the United States expanded, the Southern states wanted newly-formed states to allow slavery; this would allow pro-slavery forces to maintain their power in the U.S. Senate. The new territories acquired via the Louisiana purchase and the Mexican cession were the subject of major political crises and compromises. By 1850, the newly-rich, cotton-growing South was threatening to secede from the Union, and tensions continued to rise. Slavery was defended in the South as a "positive good", and large Protestant denominations split over the slavery issue into regional organizations of the North and South.
When Abraham Lincoln won the 1860 election on a platform of halting the expansion of slavery, seven states broke away to form the Confederacy. Shortly afterward, the Civil War began when Confederate forces attacked the US Army's Fort Sumter. Four additional slave states then seceded after Lincoln requested arms from them to make a retaliatory strike. Due to Union measures such as the Confiscation Acts and the Emancipation Proclamation in 1863, the war effectively ended slavery even before the institution was banned by constitutional amendment. Following the Union victory in the Civil War, slavery was made illegal in the United States upon the ratification of the Thirteenth Amendment in December 1865. Slavery briefly returned to US territory when the US federal government allowed the Sultanate of Sulu in the Philippines (a US possession during the first half of the twentieth century) to continue to practice slavery.
Africans first came to the New World with Christopher Columbus in 1492. Juan Las Canaries was a crewman on Columbus's flagship, the Santa Maria. Not much long after, the first enslavement occurred in what would later be the United States. In 1508, Ponce de Leon established the first settlement near present-day San Juan and began enslaving the indigenous Tainos. In 1513, to supplement the dwindling Tainos population, the first enslaved African people were imported to Puerto Rico.
The first Africans enslaved within the continental United States arrived via Santo Domingo to the San Miguel de Gualdape colony (most likely located in the Winyah Bay area of present-day South Carolina), founded by Spanish explorer Lucas Vázquez de Ayllón in 1526. The ill-fated colony was almost immediately disrupted by a fight over leadership, during which the enslaved people revolted and fled the colony to seek refuge among local Native Americans. De Ayllón and many of the colonists died shortly afterwards of an epidemic and the colony was abandoned. The settlers and the enslaved people who had not escaped returned to Santo Domingo.
On August 28, 1565, St. Augustine, Florida was founded by the Spanish conquistador Don Pedro Menendez de Aviles and he brought three enslaved Africans with him. During the 16th and 17th centuries, St. Augustine was the hub of the trade in enslaved people in Spanish colonial Florida and the first permanent settlement in what would become the continental United States to include enslaved Africans.
Sixty years later, in the early years of the Chesapeake Bay settlements, colonial officials found it difficult to attract and retain laborers under the harsh frontier conditions, and there was a high mortality rate. Most laborers came from Britain as indentured laborers, signing contracts of indenture to pay with work for their passage, their upkeep, and their training, usually on a farm. The colonies had agricultural economies. These indentured laborers were often young people who intended to become permanent residents. In some cases, convicted criminals were transported to the colonies as indentured laborers, rather than being imprisoned. The indentured laborers were not slaves, but were required to work for four to seven years in Virginia to pay the cost of their passage and maintenance. Many Germans, Scots-Irish, and Irish came to the colonies in the 18th century, settling in the backcountry of Pennsylvania and further south.

The first 19 or so Africans to reach the British colonies arrived in Point Comfort, Virginia, near Jamestown, in 1619, brought by British privateers who had seized them from a captured Portuguese slave ship. Slaves were usually baptized in Africa before embarking. As English custom then considered baptized Christians exempt from slavery, colonists treated these Africans as indentured servants, and they joined about 1,000 English indentured servants already in the colony. The Africans were freed after a prescribed period and given the use of land and supplies by their former masters. The historian Ira Berlin noted that what he called the "charter generation" in the colonies was sometimes made up of mixed-race men (Atlantic Creoles) who were indentured servants, and whose ancestry was African and Iberian. They were descendants of African women and Portuguese or Spanish men who worked in African ports as traders or facilitators in the trade of enslaved people. For example, Anthony Johnson arrived in Virginia in 1621 from Angola as an indentured servant; he became free and a property owner, eventually buying and enslaving people himself. The transformation of the social status of Africans, from indentured servitude to slaves in a racial caste which they could not leave or escape, happened gradually.
There were no laws regarding slavery early in Virginia's history. But, in 1640, a Virginia court sentenced John Punch, an African, to slavery after he attempted to flee his service. The two whites with whom he fled were sentenced only to an additional year of their indenture, and three years' service to the colony. This marked the first legal sanctioning of slavery in the English colonies and was one of the first legal distinctions made between Europeans and Africans.
In 1641, Massachusetts became the first colony to authorize slavery through enacted law. Massachusetts passed the Body of Liberties, which prohibited slavery in many instances but allowed people to be enslaved if they were captives of war, if they sold themselves into slavery or were purchased elsewhere, or if they were sentenced to slavery as punishment by the governing authority. The Body of Liberties used the word "strangers" to refer to people bought and sold as slaves; they were generally not English subjects. Colonists came to equate this term with Native Americans and Africans.
In 1654, John Casor, a black indentured servant in colonial Virginia, was the first man to be declared a slave in a civil case. He had claimed to an officer that his master, Anthony Johnson, himself a free black, had held him past his indenture term. A neighbor, Robert Parker, told Johnson that if he did not release Casor, he would testify in court to this fact. Under local laws, Johnson was at risk for losing some of his headright lands for violating the terms of indenture. Under duress, Johnson freed Casor. Casor entered into a seven years' indenture with Parker. Feeling cheated, Johnson sued Parker to repossess Casor. A Northampton County, Virginia court ruled for Johnson, declaring that Parker illegally was detaining Casor from his rightful master who legally held him "for the duration of his life".
During the colonial period, the status of enslaved people was affected by interpretations related to the status of foreigners in England. England had no system of naturalizing immigrants to its island or its colonies. Since persons of African origins were not English subjects by birth, they were among those peoples considered foreigners and generally outside English common law. The colonies struggled with how to classify people born to foreigners and subjects. In 1656 Virginia, Elizabeth Key Grinstead, a mixed-race woman, successfully gained her freedom and that of her son in a challenge to her status by making her case as the baptized Christian daughter of the free Englishman Thomas Key. Her attorney was an English subject, which may have helped her case. (He was also the father of her mixed-race son, and the couple married after Key was freed.)
Shortly after the Elizabeth Key trial and similar challenges, in 1662 the Virginia royal colony approved a law adopting the principle of partus sequitur ventrem (called partus, for short), stating that any children born in the colony would take the status of the mother. A child of an enslaved mother would be born into slavery, regardless if the father were a freeborn Englishman or Christian. This was a reversal of common law practice in England, which ruled that children of English subjects took the status of the father. The change institutionalized the skewed power relationships between those who enslaved people and enslaved women, freed white men from the legal responsibility to acknowledge or financially support their mixed-race children, and somewhat confined the open scandal of mixed-race children and miscegenation to within the slave quarters.
In 1672, King Charles II rechartered the Royal African Company (it had initially been set up in 1660), as an English monopoly for the African slave and commodities trade—thereafter in 1698, by statute, the English parliament opened the trade to all English subjects. The trade of enslaved people to the mid-Atlantic colonies increased substantially in the 1680s, and by 1710 the African population in Virginia had increased to 23,100 (42% of total); Maryland contained 8,000 Africans (14.5% of total). In the early 18th century, England passed Spain and Portugal to become the world's leading trader of enslaved people. From the early 18th century American merchants, especially in Charleston, S.C., challenged the monopoly of the Royal African Company, and Joseph Wragg and Benjamin Savage became the first independent traders of enslaved people to break through the monopoly by the 1730s.
The Virginia Slave codes of 1705 further defined as slaves those people imported from nations that were not Christian. Native Americans who were sold to colonists by other Native Americans (from rival tribes), or captured by Europeans during village raids, were also defined as slaves. This codified the earlier principle of non-Christian foreigner enslavement.
In 1735, the Georgia Trustees enacted a law prohibiting slavery in the new colony, which had been established in 1733 to enable the "worthy poor" as well as persecuted European Protestants to have a new start. Slavery was then legal in the other twelve English colonies. Neighboring South Carolina had an economy based on the use of enslaved labor. The Georgia Trustees wanted to eliminate the risk of slave rebellions and make Georgia better able to defend against attacks from the Spanish to the south, who offered freedom to escaped enslaved people. James Edward Oglethorpe was the driving force behind the colony, and the only trustee to reside in Georgia. He opposed slavery on moral grounds as well as for pragmatic reasons, and vigorously defended the ban on slavery against fierce opposition from Carolina merchants of enslaved people and land speculators.
The Protestant Scottish highlanders who settled what is now Darien, Georgia, added a moral anti-slavery argument, which became increasingly rare in the South, in their 1739 "Petition of the Inhabitants of New Inverness". By 1750 Georgia authorized slavery in the colony because it had been unable to secure enough indentured servants as laborers. As economic conditions in England began to improve in the first half of the 18th century, workers had no reason to leave, especially to face the risks in the colonies.
During most of the British colonial period, slavery existed in all the colonies. People enslaved in the North typically worked as house servants, artisans, laborers and craftsmen, with the greater number in cities. Many men worked on the docks and in shipping. In 1703, more than 42 percent of New York City households enslaved people, the second-highest proportion of any city in the colonies after Charleston, South Carolina. But enslaved people were also used as agricultural workers in farm communities, including in areas of upstate New York and Long Island, Connecticut, and New Jersey. By 1770 there were 397,924 Blacks in a population of 2.17 million. They were unevenly distributed. There were 14,867 in New England where they were 2.7% of the population; 34,679 in the mid-Atlantic colonies where they were 6% of the population (19,000 were in New York or 11%); and 347,378 in the five southern Colonies were they were 31% of the population
The South developed an agricultural economy dependent on commodity crops. Its planters rapidly acquired a significantly higher number and proportion of enslaved people in the population overall, as its commodity crops were labor-intensive. Early on, enslaved people in the South worked primarily on farms and plantations growing indigo, rice, and tobacco; cotton did not become a major crop until after the American Revolution and after the 1790s. Before then long-staple cotton was cultivated primarily on the Sea Islands of Georgia and South Carolina.
The invention of the cotton gin in 1793 enabled the cultivation of short-staple cotton in a wide variety of mainland areas, leading to the development of large areas of the Deep South as cotton country in the 19th century. Rice cultivation and tobacco were very labor-intensive. In 1720, about 65% of South Carolina's population was enslaved. Planters (defined by historians in the Upper South as those who held 20 enslaved people or more) used enslaved workers to cultivate commodity crops. They also worked in the artisanal trades on large plantations and in many southern port cities. Backwoods subsistence farmers, the later wave of settlers in the 18th century who settled along the Appalachian Mountains and backcountry, seldom held enslaved people.
Some of the British colonies attempted to abolish the international slave trade, fearing that the importation of new Africans would be disruptive. Virginia bills to that effect were vetoed by the British Privy Council. Rhode Island forbade the import of enslaved people in 1774. All of the colonies except Georgia had banned or limited the African slave trade by 1786; Georgia did so in 1798. Some[which?] of these laws were later repealed.
About 600,000 slaves were transported to America, or 5% of the 12 million slaves taken from Africa. About 310,000 of these persons were imported into the Thirteen Colonies before 1776: 40% directly and the rest from the Caribbean.
Slaves transported to America:
They constituted less than 5% of the twelve million enslaved people brought from Africa to the Americas. The great majority of enslaved Africans were transported to sugar colonies in the Caribbean and to Brazil. As life expectancy was short, their numbers had to be continually replenished. Life expectancy was much higher in the U.S., and the enslaved population was successful in reproduction. The number of enslaved people in the U.S. grew rapidly, reaching 4 million by the 1860 Census. From 1770 to 1860, the rate of natural growth of North American enslaved people was much greater than for the population of any nation in Europe, and it was nearly twice as rapid as that of England.
The number of enslaved and free blacks rose from 759,000 (60,000 free) in the 1790 US Census to 4,450,000 (11% free or 480,000) a 580% increase in the 1860 US Census. The white population from 3.2 million to 27 million an increase of 1180% due to high birth rates and 4.5 million immigrants overwhelmingly from Europe, 70% of whom arrived in the years 1840–1860. The percentage of the Black population went from 19.3% to 14.1%. 1790 757,208 19.3% of population of whom 697,681 92% enslaved 1860 4,441,830 14.1% of population of whom 3,953,731 89% enslaved.
Louisiana was founded as a French colony. Colonial officials in 1724 implemented Louis XIV of France's Code Noir, which regulated the slave trade and the institution of slavery in New France and French Caribbean colonies. This resulted in a different pattern of slavery in Louisiana, purchased in 1803, compared to the rest of the United States. As written, the Code Noir gave some rights to slaves, including the right to marry. Although it authorized and codified cruel corporal punishment against slaves under certain conditions, it forbade slave owners from torturing them or separating married couples (or to separate young children from their mothers). It also required the owners to instruct slaves in the Catholic faith.
Together with a more permeable historic French system that allowed certain rights to gens de couleur libres (free people of color), who were often born to white fathers and their mixed-race concubines, a far higher percentage of African Americans in Louisiana were free as of the 1830 census (13.2% in Louisiana compared to 0.8% in Mississippi, whose population was dominated by white Anglo-Americans). Most of Louisiana's "third class" of free people of color, situated between the native-born French and mass of African slaves, lived in New Orleans. The Louisiana free people of color were often literate and educated, with a significant number owning businesses, properties, and even slaves. Although Code Noir forbade interracial marriages, interracial unions were widespread under the system known as plaçage. The mixed-race offspring (creoles of color) from these unions were among those in the intermediate social caste of free people of color. The English colonies, in contrast, insisted on a binary system that treated mulatto and black slaves equally under the law, and discriminated against equally if free. But many free people of African descent were mixed race.
When the U.S. took over Louisiana, Americans from the Protestant South entered the territory and began to impose their norms. They officially discouraged interracial relationships (although white men continued to have unions with black women, both enslaved and free.) The Americanization of Louisiana gradually resulted in a binary system of race, causing free people of color to lose status as they were grouped with the slaves. They lost certain rights as they became classified by American whites as officially "black".

While a smaller number of African slaves were kept and sold in England, slavery in Great Britain had not been authorized by statute there. In 1772, it was made unenforceable at common law in England and Wales by a legal decision. The British role in the international slave trade continued until it abolished its slave trade in 1807. Slavery flourished in most of Britain's colonies, with many wealthy slave owners living in England and holding considerable power.
In early 1775 Lord Dunmore, royal governor of Virginia and slave-owner, wrote to Lord Dartmouth of his intent to free slaves owned by Patriots in case of rebellion. On November 7, 1775, Lord Dunmore issued Lord Dunmore's Proclamation which declared martial law in Virginia and promised freedom for any slaves of American patriots who would leave their masters and join the royal forces. Slaves owned by Loyalist masters, however, were unaffected by Dunmore's Proclamation. About 1500 slaves owned by Patriots escaped and joined Dunmore's forces. Most died of disease before they could do any fighting. Three hundred of these freed slaves made it to freedom in Britain.
Many slaves used the very disruption of war to escape their plantations and fade into cities or woods. For instance, in South Carolina, nearly 25,000 slaves (30% of the total enslaved population) fled, migrated, or died during the war.[further explanation needed] Throughout the South, losses of slaves were high, with many due to escapes. Slaves also escaped throughout New England and the mid-Atlantic, joining the British who had occupied New York.
In the closing months of the war, the British evacuated 20,000 freedmen from major coastal cities, transporting more than 3,000 for resettlement in Nova Scotia, where they were registered as Black Loyalists and eventually granted land. They transported others to the Caribbean islands, and some to England.
At the same time, the British were transporting Loyalists and their slaves, primarily to the Caribbean, but some to Nova Scotia. For example, over 5,000 enslaved Africans owned by Loyalists were transported in 1782 with their owners from Savannah to Jamaica and St. Augustine, Florida (then controlled by Britain). Similarly, over half of the black people evacuated in 1782 from Charleston by the British to the West Indies and Florida were slaves owned by white Loyalists.
Slaves and free blacks also fought on the side of rebels during the Revolutionary War. Washington authorized slaves to be freed who fought with the American Continental Army. Rhode Island started enlisting slaves in 1778, and promised compensation to owners whose slaves enlisted and survived to gain freedom. During the course of the war, about one fifth of the northern army was black. In 1781, Baron Closen, a German officer in the French Royal Deux-Ponts Regiment at the Battle of Yorktown, estimated the American army to be about one-quarter black. These men included both former slaves and free blacks.
Starting in 1777, the Patriots outlawed the importation of slaves state by state. They all acted to end the international trade but after the war it was later reopened in South Carolina and Georgia. In 1807 Congress acted on President Jefferson's advice and made importing slaves from abroad a federal crime, as the Constitution permitted, starting January 1, 1808.
In the 2019 issue of the New York Times Magazine on the topic of slavery in America, the occasion being the fourth centenary of the arrival of the first Africans at Jamestown in 1619, Nikole Hannah-Jones, a staff writer for the magazine, asserted that "one of the primary reasons the colonists decided to declare their independence from Britain was because they wanted to protect the institution of slavery."
The wealth and prominence that allowed Jefferson, at just 33, and the other founding fathers to believe they could successfully break off from one of the mightiest empires in the world came from the dizzying profits generated by chattel slavery. In other words, we may never have revolted against Britain if the founders had not understood that slavery empowered them to do so; nor if they had not believed that independence was required in order to ensure that slavery would continue. It is not incidental that 10 of this nation’s first 12 presidents were enslavers, and some might argue that this nation was founded not as a democracy but as a slavocracy.
Four months later, although others declined to join them, five distinguished historians (Victoria Bynum, James M. McPherson, James Oakes, Sean Wilentz, and Gordon S. Wood), in a Letter to the Editor, took issue with this and other points in Hannah-Jones' article:
On the American Revolution, pivotal to any account of our history, the project asserts that the founders declared the colonies’ independence of Britain “in order to ensure slavery would continue.” This is not true. If supportable, the allegation would be astounding — yet every statement offered by the project to validate it is false.
In response, Jake Silverstein, Editor-in-Chief of The Magazine, defended the article and stated that he did not believe this criticism was warranted. He wrote:
The work of various historians, among them David Waldstreicher and Alfred W. and Ruth G. Blumrosen, supports the contention that uneasiness among slaveholders in the colonies about growing antislavery sentiment in Britain and increasing imperial regulation helped motivate the Revolution.... [T]he [Somerset] ruling caused a sensation.... Numerous colonial newspapers covered it and warned of the tyranny it represented. Multiple historians have pointed out that in part because of the Somerset case, slavery joined other issues in helping to gradually drive apart the patriots and their colonial governments. ...[L]arge numbers of the enslaved came to see the struggle as one between freedom [under the British] and continued subjugation. As Waldstreicher writes, “The black-British alliance decisively pushed planters in these [Southern] states toward independence.” The culmination of this was the Dunmore Proclamation.... A member of South Carolina's delegation to the Continental Congress wrote that this act did more to sever the ties between Britain and its colonies "than any other expedient which could possibly have been thought of." The historian Jill Lepore writes in her recent book, These Truths: A History of the United States, "Not the taxes and the tea, not the shots at Lexington and Concord, not the siege of Boston; rather, it was this act, Dunmore's offer of freedom to slaves, that tipped the scales in favor of American independence."
Wilentz later argued there were many more anti-slavery activists in the colonies at the time of the Revolution than in Britain, and Hannah-Jones, while she stood by her piece, conceded she phrased the contention too strongly in a way that might mislead about all the colonies and people involved. She said subsequent materials based on the series would later be better contextualized.
Slavery was a contentious issue in the writing and approval of the Constitution of the United States. In it the words "slave" and "slavery" do not appear, although several provisions clearly refer to it. The Constitution did not prohibit slavery.
Section 9 of Article I forbade the Federal government from preventing the importation of slaves before January 1, 1808.
In a section negotiated by James Madison of Virginia, Section 2 of Article I designated "other persons" (slaves) to be added to the total of the state's free population, at the rate of three-fifths of their total number, to establish the state's official population for the purposes of apportionment of Congressional representation and federal taxation. This disproportionately strengthened the political power of Southern representatives, as three-fifths of the (non-voting) slave population was counted for Congressional apportionment and in the Electoral College.
In addition, many parts of the country were tied to the Southern economy. As the historian James Oliver Horton noted, prominent slaveholder politicians and the commodity crops of the South had a strong influence on United States politics and economy. Horton said,
in the 72 years between the election of George Washington and the election of Abraham Lincoln, 50 of those years [had] a slaveholder as president of the United States, and, for that whole period of time, there was never a person elected to a second term who was not a slaveholder.
The power of Southern states in Congress lasted until the Civil War, affecting national policies, legislation, and appointments. One result was that justices appointed to the Supreme Court were also primarily slave owners. The planter elite dominated the Southern Congressional delegations and the United States presidency for nearly 50 years.
The U.S. Constitution barred the federal government from prohibiting the importation of slaves for 20 years. Various states passed different restrictions on the international slave trade during that period; by 1808, the only state still allowing the importation of African slaves was South Carolina. After 1808, legal importation of slaves ceased, although there was smuggling via lawless Spanish Florida and the disputed Gulf Coast to the west.:48–49:138 This route all but ended after Florida became a U.S. territory in 1821 (but see Wanderer and Clotilda).
American slavery, in law and in practice, ...exceed[s] every other in severity and cool atrocity.— Isaac Knapp, Preface to Narrative of
James Williams, an American slave, 1838.
The replacement for the importation of slaves from abroad was increased domestic production. Virginia and Maryland had little new agricultural development, and their need for slaves was mostly for replacements for decedents. Normal reproduction more than supplied these: Virginia and Maryland had surpluses of slaves. Their tobacco farms were "worn out" and the climate was not suitable for cotton or sugar cane. The surplus was even greater because slaves were encouraged to reproduce (though they could not marry). The white supremacist Virginian Thomas Roderick Dew wrote in 1832 that Virginia was a "negro-raising state"; i.e. Virginia "produced" slaves.:2 According to him, in 1832 Virginia exported "upwards of 6,000 slaves" per year, "a source of wealth to Virginia".:198 Another writer gives the figure in 1836 as 40,000, earning for Virginia an estimated $24,000,000 per year.:201 Where demand for slaves was the strongest in what was then the southwest of the country: Alabama, Mississippi, and Louisiana, and later Texas, Arkansas, and Missouri. Here there was abundant land suitable for plantation agriculture, which young men with some capital established. This was expansion of the white, monied population: younger men seeking their fortune.
The most valuable crop that could be grown on a plantation in that climate was cotton. That crop was labor-intensive, and the least-costly laborers were slaves. Demand for slaves exceeded the supply in the southwest; therefore slaves, never cheap if they were productive, went for a higher price. As portrayed in Uncle Tom's Cabin (the "original" cabin was in Maryland), "selling South" was greatly feared. A recently (2018) publicized example of the practice of "selling South" is the 1838 sale by Jesuits of 272 slaves from Maryland, to plantations in Louisiana, to benefit Georgetown University, which "owes its existence" to this transaction.
Traders responded to the demand, including John Armfield and his uncle Isaac Franklin, who were "reputed to have made over half a million dollars (in 19th-century value)" in the slave trade. (They did not handle the Jesuit transaction just mentioned.) Setting up an office in what was then the District of Columbia, regional center of the slave trade, in Alexandria, "a major slave trading port for more than a century", the two men went into business in 1828 buying slaves in the North and selling them in the South:
Cash in Market.
The subscribers having leased for a term of years the large three story brick house on Duke Street, in the town of Alexandria, D.C. formerly occupied by Gen. Young, we wish to purchase one hundred and fifty likely young negroes of both sexes, between the ages of 8 and 25 years. Persons who wish to sell will do well to give us a call, as we are determined to give more than any other purchasers that are in market, or that may hereafter come into market.
Any letters addressed to the subscribers through the Post Office at Alexandria, will be promptly attended to. For information, enquire at the above described house, as we can at all times be found there.
FRANKLIN & ARMFIELD— advertisement in the Alexandria Phoenix Gazette, May 17, 1828
This house on Duke Street houses the Freedom House Museum, with exhibits on the slave trade and the lives of slaves.
Armfield remained in Alexandria doing the purchasing, with agents in Richmond and Warrenton, Virginia, and Baltimore, Frederick, and Easton, Maryland (on Maryland's Eastern Shore, near Delaware). Franklin handled the selling out of New Orleans and Natchez, Mississippi, with offices in St. Francisville and Vidalia, Louisiana. Their partnership grew to the point that when the partnership was dissolved in 1836 and the business sold, they owned six ships for the sole purpose of transporting slaves, with monthly and then biweekly sailings. (The ships carried agricultural products on the return trips.) One of them, the Isaac Franklin, was built for them.
Franklin and Armfield's Alexandria site was visited by various abolitionists, who have left detailed descriptions of it. They concur in that Armfield, in contrast with Robert Lumpkin among others, was the most scrupulous of the major slave traders, who would not knowingly purchase kidnapped slaves or freedmen, and whose slaves were reasonably well treated while he owned them, at least at the Duke Street facility. Slaves appeared to concur in this relatively positive picture, asking that if they were to be sold, that they be sold to Armfield. However, Armfield frequently took children from their parents and sold them South.
In the United States in the early nineteenth century, owners of female slaves could freely and legally use them as sexual objects. This follows free use of female slaves on slaving vessels by the crews.:83 "The slaveholder has it in his power, to violate the chastity of his slaves. And not a few are beastly enough to exercise such power. Hence it happens that, in some families, it is difficult to distinguish the free children from the slaves. It is sometimes the case, that the largest part of the master's own children are born, not of his wife, but of the wives and daughters of his slaves, whom he has basely prostituted as well as enslaved.":38 "This vice, this bane of society, has already become so common, that it is scarcely esteemed a disgrace."
"Fancy" was a code word that indicated the girl or young woman was suitable for or trained for sexual use.:56 In some cases, children were also abused in this manner. The sale of a 13-year-old "nearly a fancy" is documented. Zephaniah Kingsley, Jr., bought his wife when she was 13.:191
Furthermore, females of breeding age were supposed to be kept pregnant, producing more slaves to sell. The variations in skin color found in the United States make it obvious how often black women were impregnated by whites.:78–79 For example, in the 1850 Census, 75.4% of "free negros" in Florida were described as mulattos, of mixed race.:2 Nevertheless, it is only very recently, with DNA studies, that any sort of reliable number can be provided, and the research has only begun. Light-skinned girls, who contrasted with the darker field workers, were preferred.
The sexual use of black slaves by white men, either slave owners or those who could purchase the temporary services of a slave, took various forms. A slaveowner, or his teenage sons, could go to the slave quarters area of the plantation and do what he wanted, usually in front of the rest of the slaves, or with minimal privacy. It was common for a "house" female — a housekeeper, maid, cook, laundress, or nanny — to be used by one or more white males of the household for their sexual enjoyment. Houses of prostitution throughout the slave states were largely staffed by female slaves providing sexual services, to their owners' profit. There were a small number of free black females engaged in prostitution, or concubinage, especially in New Orleans.:41
White men who engaged in sexual activity with female slaves "were often the elite of the community. They had little need to worry about public scorn." These relationships "appear to have been tolerated and in some cases even quietly accepted." "Southern women…do not trouble themselves about it".
Light-skinned young girls were sold openly for sexual use; their price was much higher than that of a field hand.:38, 55 Special markets for the fancy girl trade existed in New Orleans:55 and Lexington, Kentucky. Historian Philip Shaw describes an occasion when Abraham Lincoln and Allen Gentry witnessed such sales in New Orleans in 1828:
Gentry vividly remembered a day in New Orleans when he and the nineteen-year-old Lincoln came upon a slave market. Pausing to watch, Gentry recalled looking down at Lincoln's hands and seeing that he "doubled his fists tightly; his knuckles went white." Men wearing black coats and white hats buy field hands, "black and ugly," for $500 to 800. And then the real horror begins: "When the sale of "fancy girls" began, Lincoln, "unable to stand it any longer," muttered to Gentry "Allen that's a disgrace. If I ever get a lick at that thing I'll hit it hard."
Those "considered educated and refined, were purchased by the wealthiest clients, usually plantation owners, to become personal sexual companions." "There was a great demand in New Orleans for 'fancy girls'."
The issue which did come up frequently was the exaggerated threat of sexual intercourse between black male and white female. Just as the black women were perceived as having "a trace of Africa, that supposedly incited passion and sexual wantonness",:39 the men were perceived as savages, unable to control their lust, given an opportunity.:212–213
Another approach to the question was offered by Quaker and Florida planter Zephaniah Kingsley, Jr. He advocated, and personally practiced, deliberate racial mixing through marriage, as part of his proposed solution to the slavery issue: racial integration, called "amalgamation" at the time. In an 1829 Treatise, he stated that mixed-race people were healthier and often more beautiful, that interracial sex was hygienic, and that slavery made it convenient.:190 Because of these views, tolerated in Spanish Florida, he found it impossible to remain long in Territorial Florida, and moved with his slaves and multiple wives to a plantation in Haiti (now in the Dominican Republic). There were many others who less flagrantly practiced interracial, common-law marriages with slaves (see Partus sequitur ventrem).
In the 19th century, proponents of slavery often defended the institution as a "necessary evil". White people of that time feared that emancipation of black slaves would have more harmful social and economic consequences than the continuation of slavery. In 1820, Thomas Jefferson, one of the Founding Fathers of the United States, wrote in a letter that with slavery:
We have the wolf by the ear, and we can neither hold him, nor safely let him go. Justice is in one scale, and self-preservation in the other.
The French writer and traveler Alexis de Tocqueville, in his influential Democracy in America (1835), expressed opposition to slavery while observing its effects on American society. He felt that a multiracial society without slavery was untenable, as he believed that prejudice against blacks increased as they were granted more rights (for example, in northern states). He believed that the attitudes of white Southerners, and the concentration of the black population in the South, were bringing the white and black populations to a state of equilibrium, and were a danger to both races. Because of the racial differences between master and slave, he believed that the latter could not be emancipated.
Robert E. Lee wrote in 1856:
There are few, I believe, in this enlightened age, who will not acknowledge that slavery as an institution is a moral and political evil. It is idle to expatiate on its disadvantages. I think it is a greater evil to the white than to the colored race. While my feelings are strongly enlisted in behalf of the latter, my sympathies are more deeply engaged for the former. The blacks are immeasurably better off here than in Africa, morally, physically, and socially. The painful discipline they are undergoing is necessary for their further instruction as a race, and will prepare them, I hope, for better things. How long their servitude may be necessary is known and ordered by a merciful Providence.
However, as the abolitionist movement's agitation increased and the area developed for plantations expanded, apologies for slavery became more faint in the South. Leaders then described slavery as a beneficial scheme of labor management. John C. Calhoun, in a famous speech in the Senate in 1837, declared that slavery was "instead of an evil, a good—a positive good". Calhoun supported his view with the following reasoning: in every civilized society one portion of the community must live on the labor of another; learning, science, and the arts are built upon leisure; the African slave, kindly treated by his master and mistress and looked after in his old age, is better off than the free laborers of Europe; and under the slave system conflicts between capital and labor are avoided. The advantages of slavery in this respect, he concluded, "will become more and more manifest, if left undisturbed by interference from without, as the country advances in wealth and numbers".
South Carolina Army officer, planter, and railroad executive James Gadsden called slavery "a social blessing" and abolitionists "the greatest curse of the nation". Gadsden was in favor of South Carolina's secession in 1850, and was a leader in efforts to split California into two states, one slave and one free.
Other Southern writers who also began to portray slavery as a positive good were James Henry Hammond and George Fitzhugh. They presented several arguments to defend the practice of slavery in the South. Hammond, like Calhoun, believed that slavery was needed to build the rest of society. In a speech to the Senate on March 4, 1858, Hammond developed his "Mudsill Theory," defending his view on slavery stating: "Such a class you must have, or you would not have that other class which leads progress, civilization, and refinement. It constitutes the very mud-sill of society and of political government; and you might as well attempt to build a house in the air, as to build either the one or the other, except on this mud-sill." Hammond believed that in every class one group must accomplish all the menial duties, because without them the leaders in society could not progress. He argued that the hired laborers of the North were slaves too: "The difference… is, that our slaves are hired for life and well compensated; there is no starvation, no begging, no want of employment," while those in the North had to search for employment.
George Fitzhugh used assumptions about white superiority to justify slavery, writing that, "the Negro is but a grown up child, and must be governed as a child." In The Universal Law of Slavery, Fitzhugh argues that slavery provides everything necessary for life and that the slave is unable to survive in a free world because he is lazy, and cannot compete with the intelligent European white race. He states that "The negro slaves of the South are the happiest, and in some sense, the freest people in the world." Without the South, "He (slave) would become an insufferable burden to society" and "Society has the right to prevent this, and can only do so by subjecting him to domestic slavery."
On March 21, 1861, Alexander Stephens, Vice President of the Confederacy, delivered his Cornerstone Speech. He explained the differences between the Confederate States Constitution and the United States Constitution, laid out the cause for the American Civil War, as he saw it, and defended slavery:
The new Constitution has put at rest forever all the agitating questions relating to our peculiar institutions—African slavery as it exists among us—the proper status of the negro in our form of civilization. This was the immediate cause of the late rupture and present revolution. Jefferson, in his forecast, had anticipated this, as the "rock upon which the old Union would split." He was right. What was conjecture with him, is now a realized fact. But whether he fully comprehended the great truth upon which that rock stood and stands, may be doubted. The prevailing ideas entertained by him and most of the leading statesmen at the time of the formation of the old Constitution were, that the enslavement of the African was in violation of the laws of nature; that it was wrong in principle, socially, morally and politically. It was an evil they knew not well how to deal with; but the general opinion of the men of that day was, that, somehow or other, in the order of Providence, the institution would be evanescent and pass away... Those ideas, however, were fundamentally wrong. They rested upon the assumption of the equality of races. This was an error. It was a sandy foundation, and the idea of a Government built upon it—when the "storm came and the wind blew, it fell."
Our new Government is founded upon exactly the opposite ideas; its foundations are laid, its cornerstone rests, upon the great truth that the negro is not equal to the white man; that slavery, subordination to the superior race, is his natural and moral condition.
This view of the negro "race" was backed by pseudo-science. The leading researcher was Dr. Samuel A. Cartwright, inventor of the mental illnesses of drapetomania—the desire of a slave to run away—and dysaesthesia aethiopica—"rascality", cured by whipping. The Medical Association of Louisiana set up a committee, of which he was chair, to investigate "The Diseases and Physical Peculiarities of the Negro Race". Their report, first delivered to the Medical Association in an address, was published in their journal, and then reprinted in part in the widely circulated DeBow's Review.
Whether or not slavery was to be limited to the Southern states that already had it, or whether it was to be permitted in new states made from the lands of the Louisiana Purchase and Mexican Cession, was a major issue in the 1840s and 1850s. Results included the Compromise of 1850 and the Bleeding Kansas period.
Also relatively well known are the proposals, including the Ostend Manifesto, to annex Cuba as a slave state. There was also talk of making slave states of Mexico, Nicaragua (see Walker affair), and other lands around the so-called Golden Circle. Less well known today (2019), though well known at the time, is that pro-slavery Southerners:
While these ideas never got off the ground, they alarmed Northerners and contributed to the growing polarization of the country.
Slavery is a volcano, the fires of which cannot be quenched, nor its ravishes controlled. We already feel its convulsions, and if we sit idly gazing upon its flames, as they rise higher and higher, our happy republic will be buried in ruin, beneath its overwhelming energies.
William Ellsworth, attorney for Prudence Crandall, 1834:193–194
Beginning during the revolution and in the first two decades of the postwar era, every state in the North abolished slavery. These were the first abolitionist laws in the Atlantic World. However, the abolition of slavery did not necessarily mean that existing slaves became free. In some states they were forced to remain with their former owners as indentured servants: free in name only, although they could not be sold and thus families could not be split, and their children were born free. The end of slavery did not come in New York until July 4, 1827, when it was celebrated with a big parade. However, in the 1830 census, the only state with no slaves was Vermont. In the 1840 census, there were still slaves in New Hampshire (1), Rhode Island (5), Connecticut (17), New York (4), Pennsylvania (64), Ohio (3), Indiana (3), Illinois (331), Iowa (16), and Wisconsin (11). There were none in these states in the 1850 census.
In Massachusetts, slavery was successfully challenged in court in 1783 in a freedom suit by Quock Walker; he said that slavery was in contradiction to the state's new constitution of 1780 providing for equality of men. Freed slaves were subject to racial segregation and discrimination in the North, and in many cases they did not have the right to vote until ratification of the Fifteenth Amendment in 1870.
Most Northern states passed legislation for gradual abolition, first freeing children born to slave mothers (and requiring them to serve lengthy indentures to their mother's masters, often into their 20s as young adults). Pennsylvania's last ex-slaves were freed in 1847, Connecticut's in 1848, and while neither New Hampshire nor New Jersey had any slaves in the 1850 Census, and New Jersey only 1 and New Hamphire none in the 1860 Census, slavery was never prohibited in either state until ratification of the 13th Amendment in 1865 (and New Jersey was one of the last states to ratify it).
None of the Southern states abolished slavery before 1865, but it was not unusual for individual slaveholders in the South to free numerous slaves, often citing revolutionary ideals, in their wills. Methodist, Quaker, and Baptist preachers traveled in the South, appealing to slaveholders to manumit their slaves, and there were "manumission societies" in some Southern states. By 1810, the number and proportion of free blacks in the population of the United States had risen dramatically. Most free blacks lived in the North, but even in the Upper South, the proportion of free blacks went from less than one percent of all blacks to more than 10 percent, even as the total number of slaves was increasing through imports.
Through the Northwest Ordinance of 1787, passed by the Congress of the Confederation, slavery was prohibited in the territories northwest of the Ohio River; existing slaves were not freed for years, although they could no longer be sold. This was a compromise. Thomas Jefferson proposed in 1784 to end slavery in all the territories, but his bill lost in the Congress by one vote. The territories south of the Ohio River (and Missouri) had authorized slavery.
Northerners predominated in the westward movement into the Midwestern territory after the American Revolution; as the states were organized, they voted to prohibit slavery in their constitutions when they achieved statehood: Ohio in 1803, Indiana in 1816, and Illinois in 1818. What developed was a Northern block of free states united into one contiguous geographic area that generally shared an anti-slavery culture. The exceptions were the areas along the Ohio River settled by Southerners: the southern portions of Indiana, Ohio, and Illinois. Residents of those areas generally shared in Southern culture and attitudes. In addition, these areas were devoted to agriculture longer than the industrializing northern parts of these states, and some farmers used slave labor. In Illinois, for example, while the trade in slaves was prohibited, it was legal to bring slaves from Kentucky into Illinois and use them there, as long as the slaves left Illinois one day per year (they were "visiting"). The emancipation of slaves in the North led to the growth in the population of Northern free blacks, from several hundred in the 1770s to nearly 50,000 by 1810.
There was legal agitation against slavery in the 13 colonies starting in 1752 by lawyer Benjamin Kent, whose cases were recorded by one of his understudies, the future president John Adams. Kent represented numerous slaves in their attempts to gain their freedom. He handled the case of a slave, Pompey, suing his master. In 1766, Kent was the first lawyer in the United States to win a case to free a slave, Jenny Slew. He also won a trial in the Old County Courthouse for a slave named Ceasar Watson (1771). Kent also handled Lucy Pernam's divorce and the freedom suits of Rose and Salem Orne.
Throughout the first half of the 19th century, abolitionism, a movement to end slavery, grew in strength; most abolitionist societies and supporters were in the North. They worked to raise awareness about the evils of slavery, and to build support for abolition.
This struggle took place amid strong support for slavery among white Southerners, who profited greatly from the system of enslaved labor. But slavery was entwined with the national economy; for instance, the banking, shipping, and manufacturing industries of New York City all had strong economic interests in slavery, as did similar industries in other major port cities in the North. The northern textile mills in New York and New England processed Southern cotton and manufactured clothes to outfit slaves. By 1822 half of New York City's exports were related to cotton.
The principal organized bodies to advocate abolition and anti-slavery reforms in the north were the Pennsylvania Abolition Society and the New York Manumission Society. Before the 1830s the antislavery groups called for gradual emancipation. By the late 1820s, under the impulse of religious evangelicals such as Beriah Green, the sense emerged that owning slaves was a sin and the owner had to immediately free himself from this grave sin by immediate emancipation.
In the early part of the 19th century, other organizations were founded to take action on the future of black Americans. Some advocated removing free black people from the United States to places where they would enjoy greater freedom; some endorsed colonization in Africa, while others advocated emigration, usually to Haiti. During the 1820s and 1830s, the American Colonization Society (ACS) was the primary organization to implement the "return" of black Americans to Africa. The ACS was made up mostly of Quakers and slaveholders, who found uneasy common ground in support of what was incorrectly called "repatriation". But by this time most black Americans were native-born and did not want to emigrate, saying they were no more African than the Americans were British. Rather, they wanted full rights in the United States, where their families had lived and worked for generations.
In 1822 the ACS and affiliated state societies established what would become the colony of Liberia, in West Africa. The ACS assisted thousands of freedmen and free blacks (with legislated limits) to emigrate there from the United States. Many white people considered this preferable to emancipation in the United States. Henry Clay, one of the founders and a prominent slaveholder politician from Kentucky, said that blacks faced
unconquerable prejudice resulting from their color, they never could amalgamate with the free whites of this country. It was desirable, therefore, as it respected them, and the residue of the population of the country, to drain them off.
Deportation would also be a way to prevent reprisals against former slaveholders and white people in general, as had occurred in the 1804 Haiti massacre. After 1830, abolitionist and newspaper publisher William Lloyd Garrison promoted emancipation, characterizing slaveholding as a personal sin. He demanded that slaveowners repent and start the process of emancipation. His position increased defensiveness on the part of some Southerners, who noted the long history of slavery among many cultures. A few abolitionists, such as John Brown, favored the use of armed force to foment uprisings among the slaves, as he attempted to do at Harper's Ferry. Most abolitionists tried to raise public support to change laws and to challenge slave laws. Abolitionists were active on the lecture circuit in the North, and often featured escaped slaves in their presentations. The eloquent Frederick Douglass became an important abolitionist leader after escaping from slavery. Harriet Beecher Stowe's novel Uncle Tom's Cabin (1852) was an international bestseller and aroused popular sentiment against slavery. It also provoked the publication of numerous anti-Tom novels by Southerners in the years before the American Civil War.
While under the Constitution, Congress could not prohibit the import slave trade until 1808, the third Congress regulated it in the Slave Trade Act of 1794, which prohibited shipbuilding and outfitting for the trade. Subsequent acts in 1800 and 1803 sought to discourage the trade by limiting investment in import trading and prohibiting importation into states that had abolished slavery, which most in the North had by that time. The final Act Prohibiting Importation of Slaves was adopted in 1807, effective in 1808. However, illegal importation of African slaves (smuggling) was common.
After Great Britain and the United States outlawed the international slave trade in 1807, British slave trade suppression activities began in 1808 through diplomatic efforts and formation of the Royal Navy's West Africa Squadron. From 1819, they were assisted by forces from the United States Navy. With the Webster-Ashburton Treaty of 1842, the relationship with Britain was formalized, and the two countries jointly ran the Blockade of Africa with their navies.
Although Virginia, Maryland, and Delaware were slave states, the latter two already had a high proportion of free blacks by the outbreak of war. Following the Revolution, the three legislatures made manumission easier, allowed by deed or will. Quaker and Methodist ministers particularly urged slaveholders to free their slaves. The number and proportion of freed slaves in these states rose dramatically until 1810. More than half of the number of free blacks in the United States were concentrated in the Upper South. The proportion of free blacks among the black population in the Upper South rose from less than 1% in 1792 to more than 10% by 1810. In Delaware, nearly 75% of blacks were free by 1810.
In the US as a whole, by 1810 the number of free blacks reached 186,446, or 13.5% of all blacks. After that period few slaves were freed, as the development of cotton plantations featuring short-staple cotton in the Deep South drove up the internal demand for slaves in the domestic slave trade and high prices were paid.
South Carolina made manumission more difficult, requiring legislative approval of every instance of manumission. Several Southern states required manumitted slaves to leave the state within 30 days.
The growing international demand for cotton led many plantation owners further west in search of suitable land. In addition, the invention of the cotton gin in 1793 enabled profitable processing of short-staple cotton, which could readily be grown in the uplands. The invention revolutionized the cotton industry by increasing fifty-fold the quantity of cotton that could be processed in a day. At the end of the War of 1812, fewer than 300,000 bales of cotton were produced nationally. By 1820 the amount of cotton produced had increased to 600,000 bales, and by 1850 it had reached 4,000,000. There was an explosive growth of cotton cultivation throughout the Deep South and greatly increased demand for slave labor to support it. As a result, manumissions decreased dramatically in the South.
Most of the slaves sold from the Upper South were from Maryland, Virginia, and the Carolinas, where changes in agriculture decreased the need for their labor and the demand for slaves. Before 1810, primary destinations for the slaves who were sold were Kentucky and Tennessee, but after 1810 Georgia, Alabama, Mississippi, Louisiana, and Texas, Deep South states, received the most slaves. This is where cotton became king. Kentucky and Tennessee joined the slave exporting states.
By 1815, the domestic slave trade had become a major economic activity in the United States; it lasted until the 1860s. Between 1830 and 1840 nearly 250,000 slaves were taken across state lines. In the 1850s more than 193,000 were transported, and historians estimate nearly one million in total took part in the forced migration of this new Middle Passage. By 1860 the slave population in the United States had reached 4 million. Of all 1,515,605 free families in the fifteen slave states in 1860, nearly 400,000 held slaves (roughly one in four, or 25%), amounting to 8% of all American families.
The historian Ira Berlin called this forced migration of slaves the "Second Middle Passage", because it reproduced many of the same horrors as the Middle Passage (the name given to the transportation of slaves from Africa to North America). These sales of slaves broke up many families and caused much hardship. Characterizing it as the "central event" in the life of a slave between the American Revolution and the Civil War, Berlin wrote that whether slaves were directly uprooted or lived in fear that they or their families would be involuntarily moved, "the massive deportation traumatized black people, both slave and free." Individuals lost their connection to families and clans. Added to the earlier colonists combining slaves from different tribes, many ethnic Africans lost their knowledge of varying tribal origins in Africa. Most were descended from families who had been in the United States for many generations.
In the 1840s, almost 300,000 slaves were transported, with Alabama and Mississippi receiving 100,000 each. During each decade between 1810 and 1860, at least 100,000 slaves were moved from their state of origin. In the final decade before the Civil War, 250,000 were moved. Michael Tadman wrote in Speculators and Slaves: Masters, Traders, and Slaves in the Old South (1989) that 60–70% of inter-regional migrations were the result of the sale of slaves. In 1820 a child in the Upper South had a 30% chance of being sold south by 1860. The death rate for the slaves on their way to their new destination across the American South was less than that suffered by captives shipped across the Atlantic Ocean, but mortality was higher than the normal death rate.
Slave traders transported two-thirds of the slaves who moved west. Only a minority moved with their families and existing master. Slave traders had little interest in purchasing or transporting intact slave families; in the early years, planters demanded only the young male slaves needed for heavy labor. Later, in the interest of creating a "self-reproducing labor force", planters purchased nearly equal numbers of men and women. Berlin wrote:
The internal slave trade became the largest enterprise in the South outside the plantation itself, and probably the most advanced in its employment of modern transportation, finance, and publicity. The slave trade industry developed its own unique language, with terms such as "prime hands, bucks, breeding wenches, and "fancy girls" coming into common use.
The expansion of the interstate slave trade contributed to the "economic revival of once depressed seaboard states" as demand accelerated the value of slaves who were subject to sale.
Some traders moved their "chattels" by sea, with Norfolk to New Orleans being the most common route, but most slaves were forced to walk overland. Others were shipped downriver from such markets as Louisville on the Ohio River, and Natchez on the Mississippi. Traders created regular migration routes served by a network of slave pens, yards, and warehouses needed as temporary housing for the slaves. In addition, other vendors provided clothes, food, and supplies for slaves. As the trek advanced, some slaves were sold and new ones purchased. Berlin concluded, "In all, the slave trade, with its hubs and regional centers, its spurs and circuits, reached into every cranny of southern society. Few southerners, black or white, were untouched."
Once the trip ended, slaves faced a life on the frontier significantly different from most labor in the Upper South. Clearing trees and starting crops on virgin fields was harsh and backbreaking work. A combination of inadequate nutrition, bad water, and exhaustion from both the journey and the work weakened the newly arrived slaves and produced casualties. New plantations were located at rivers' edges for ease of transportation and travel. Mosquitoes and other environmental challenges spread disease, which took the lives of many slaves. They had acquired only limited immunities to lowland diseases in their previous homes. The death rate was so high that, in the first few years of hewing a plantation out of the wilderness, some planters preferred whenever possible to use rented slaves rather than their own.
The harsh conditions on the frontier increased slave resistance and led owners and overseers to rely on violence for control. Many of the slaves were new to cotton fields and unaccustomed to the "sunrise-to-sunset gang labor" required by their new life. Slaves were driven much harder than when they had been in growing tobacco or wheat back east. Slaves had less time and opportunity to improve the quality of their lives by raising their own livestock or tending vegetable gardens, for either their own consumption or trade, as they could in the east.
In Louisiana, French colonists had established sugar cane plantations and exported sugar as the chief commodity crop. After the Louisiana Purchase in 1803, Americans entered the state and joined the sugar cultivation. Between 1810 and 1830, planters bought slaves from the North and the number of slaves increased from less than 10,000 to more than 42,000. Planters preferred young males, who represented two-thirds of the slave purchases. Dealing with sugar cane was even more physically demanding than growing cotton. The largely young, unmarried male slave force made the reliance on violence by the owners "especially savage".
New Orleans became nationally important as a slave market and port, as slaves were shipped from there upriver by steamboat to plantations on the Mississippi River; it also sold slaves who had been shipped downriver from markets such as Louisville. By 1840, it had the largest slave market in North America. It became the wealthiest and the fourth-largest city in the nation, based chiefly on the slave trade and associated businesses. The trading season was from September to May, after the harvest.
Slave traders were men of low reputation, even in the South. In the 1828 presidential election, candidate Andrew Jackson was strongly criticized by opponents as a slave trader who transacted in slaves in defiance of modern standards or morality.
The treatment of slaves in the United States varied widely depending on conditions, times and places. The power relationships of slavery corrupted many whites who had authority over slaves, with children showing their own cruelty. Masters and overseers resorted to physical punishments to impose their wills. Slaves were punished by whipping, shackling, hanging, beating, burning, mutilation, branding and imprisonment. Punishment was most often meted out in response to disobedience or perceived infractions, but sometimes abuse was carried out to re-assert the dominance of the master or overseer of the slave. Treatment was usually harsher on large plantations, which were often managed by overseers and owned by absentee slaveholders, conditions permitting abuses.
William Wells Brown, who escaped to freedom, reported that on one plantation, slave men were required to pick 80 pounds per day of cotton, while women were required to pick 70 pounds; if any slave failed in his or her quota, they were subject to whip lashes for each pound they were short. The whipping post stood next to the cotton scales. A New York man who attended a slave auction in the mid-19th century reported that at least three-quarters of the male slaves he saw at sale had scars on their backs from whipping. By contrast, small slave-owning families had closer relationships between the owners and slaves; this sometimes resulted in a more humane environment but was not a given.
Historian Lawrence M. Friedman wrote: "Ten Southern codes made it a crime to mistreat a slave. … Under the Louisiana Civil Code of 1825 (art. 192), if a master was "convicted of cruel treatment," the judge could order the sale of the mistreated slave, presumably to a better master." Masters and overseers were seldom prosecuted under these laws. No slave could give testimony in the courts.
According to Adalberto Aguirre, there were 1,161 slaves executed in the U.S. between the 1790s and 1850s. Quick executions of innocent slaves as well as suspects typically followed any attempted slave rebellions, as white militias overreacted with widespread killings that expressed their fears of rebellions, or suspected rebellions.
Although most slaves had lives that were very restricted in terms of their movements and agency, exceptions existed to virtually every generalization; for instance, there were also slaves who had considerable freedom in their daily lives: slaves allowed to rent out their labor and who might live independently of their master in cities, slaves who employed white workers, and slave doctors who treated upper-class white patients. After 1820, in response to the inability to import new slaves from Africa and in part to abolitionist criticism, some slaveholders improved the living conditions of their slaves, to encourage them to be productive and to try to prevent escapes. It was part of a paternalistic approach in the antebellum era that was encouraged by ministers trying to use Christianity to improve the treatment of slaves. Slaveholders published articles in southern agricultural journals to share best practices in treatment and management of slaves; they intended to show that their system was better than the living conditions of northern industrial workers.
Medical care for slaves was limited in terms of the medical knowledge available to anyone. It was generally provided by other slaves or by slaveholders' family members, although sometimes "plantation physicians", like J. Marion Sims, were called by the owners to protect their investment by treating sick slaves. Many slaves possessed medical skills needed to tend to each other, and used folk remedies brought from Africa. They also developed new remedies based on American plants and herbs.
According to Andrew Fede, a master could be held criminally liable for killing a slave only if the slave he killed was "completely submissive and under the master's absolute control". For example, in 1791 the North Carolina legislature defined the willful killing of a slave as criminal murder, unless done in resisting or under moderate correction (that is, corporal punishment).
Because of the power relationships at work, slave women in the United States were at high risk for rape and sexual abuse. Many slaves fought back against sexual attacks, and some died resisting. Others carried psychological and physical scars from the attacks. Sexual abuse of slaves was partially rooted in a patriarchal Southern culture which treated black women as property or chattel. Southern culture strongly policed against sexual relations between white women and black men on the purported grounds of racial purity but, by the late 18th century, the many mixed-race slaves and slave children showed that white men had often taken advantage of slave women. Wealthy planter widowers, notably such as John Wayles and his son-in-law Thomas Jefferson, took slave women as concubines; each had six children with his partner: Elizabeth Hemings and her daughter Sally Hemings (the half-sister of Jefferson's late wife), respectively. Both Mary Chesnut and Fanny Kemble, wives of planters, wrote about this issue in the antebellum South in the decades before the Civil War. Sometimes planters used mixed-race slaves as house servants or favored artisans because they were their children or other relatives. As a result of centuries of slavery and such relationships, DNA studies have shown that the vast majority of African Americans also have historic European ancestry, generally through paternal lines.
To help regulate the relationship between slave and owner, including legal support for keeping the slave as property, states established slave codes, most based on laws existing since the colonial era. The code for the District of Columbia defined a slave as "a human being, who is by law deprived of his or her liberty for life, and is the property of another".
While each state had its own slave code, many concepts were shared throughout the slave states. According to the slave codes, some of which were passed in reaction to slave rebellions, teaching a slave to read or write was illegal. This prohibition was unique to American slavery, believed to reduce slaves forming aspirations that could lead to escape or rebellion. Informal education occurred when white children taught slave companions what they were learning; in other cases, adult slaves learned from free artisan workers, especially if located in cities, where there was more freedom of movement.
In Alabama, slaves were not allowed to leave their master's premises without written consent or passes. This was a common requirement in other states as well, and locally run patrols (known to slaves as pater rollers) often checked the passes of slaves who appeared to be away from their plantations. In Alabama slaves were prohibited from trading goods among themselves. In Virginia, a slave was not permitted to drink in public within one mile of his master or during public gatherings. Slaves were not permitted to carry firearms in any of the slave states.
Slaves were generally prohibited by law from associating in groups, with the exception of worship services (a reason why the Black church is such a notable institution in black communities today). Following Nat Turner's rebellion in 1831, which raised white fears throughout the South, some states also prohibited or restricted religious gatherings of slaves, or required that they be officiated by white men. Planters feared that group meetings would facilitate communication among slaves that could lead to rebellion. Slaves held private, secret "brush meetings" in the woods.
In Ohio, an emancipated slave was prohibited from returning to the state in which he or she had been enslaved. Other northern states discouraged the settling of free blacks within their boundaries. Fearing the influence of free blacks, Virginia and other southern states passed laws to require blacks who had been freed to leave the state within a year (or sometimes less time) unless granted a stay by an act of the legislature.
The United States Constitution, adopted in 1787, prevented Congress from completely banning the importation of slaves until 1808, although Congress regulated it in the Slave Trade Act of 1794, and in subsequent Acts in 1800 and 1803. During and after the Revolution, the states individually passed laws against importing slaves. By contrast, the states of Georgia and South Carolina reopened their trade due to demand by their upland planters, who were developing new cotton plantations: Georgia from 1800 until December 31, 1807, and South Carolina from 1804. In that period, Charleston traders imported about 75,000 slaves, more than were brought to South Carolina in the 75 years before the Revolution. Approximately 30,000 were imported to Georgia.
By January 1, 1808, when Congress banned further imports, South Carolina was the only state that still allowed importation of slaves. The domestic slave trade became extremely profitable as demand rose with the expansion of cultivation in the Deep South for cotton and sugar cane crops. Slavery in the United States became, more or less, self-sustaining by natural increase among the current slaves and their descendants.
Despite the ban, slave imports continued through smugglers bringing in slaves past the U.S. Navy's African Slave Trade Patrol to South Carolina, and overland from Texas and Florida, both under Spanish control. Congress increased the punishment associated with importing slaves, classifying it in 1820 as an act of piracy, with smugglers subject to harsh penalties, including death if caught. After that, "it is unlikely that more than 10,000 [slaves] were successfully landed in the United States." But, some smuggling of slaves into the United States continued until just before the start of the Civil War; see Wanderer (slave ship) and Clotilde (slave ship)
During the War of 1812, British Royal Navy commanders of the blockading fleet, were instructed to offer freedom to defecting American slaves, as the Crown had during the Revolutionary War. Thousands of escaped slaves went over to the Crown with their families. Men were recruited into the Corps of Colonial Marines on occupied Tangier Island, in the Chesapeake Bay. Many freed American slaves were recruited directly into existing West Indian regiments, or newly created British Army units The British later resettled a few thousand freed slaves at Nova Scotia, as they had for freedmen after the Revolution. Some of the earlier freedmen had migrated to Sierra Leone in the late 18th century, when it was established as a British colony. Descendants have established the Black Loyalist Heritage Museum and website.
Slaveholders, primarily in the South, had considerable "loss of property" as thousands of slaves escaped to British lines or ships for freedom, despite the difficulties. The planters' complacency about slave "contentment" was shocked by seeing that slaves would risk so much to be free. Afterward, when some freed slaves had been settled at Bermuda, slaveholders such as Major Pierce Butler of South Carolina tried to persuade them to return to the United States, to no avail.
The Americans protested that Britain's failure to return all slaves violated the Treaty of Ghent. After arbitration by the Tsar of Russia, the British paid $1,204,960 in damages (about $27.2 million in today's money) to Washington, which reimbursed the slaveowners.
Prior to the American Revolution, masters and revivalists spread Christianity to slave communities, supported by the Society for the Propagation of the Gospel. In the First Great Awakening of the mid-18th century, Baptists and Methodists from New England preached a message against slavery, encouraged masters to free their slaves, converted both slaves and free blacks, and gave them active roles in new congregations. The first independent black congregations were started in the South before the Revolution, in South Carolina and Georgia.
Over the decades and with the growth of slavery throughout the South, Baptist and Methodist ministers gradually changed their messages to accommodate the institution. After 1830, white Southerners argued for the compatibility of Christianity and slavery, with a multitude of both Old and New Testament citations. They promoted Christianity as encouraging better treatment of slaves and argued for a paternalistic approach. In the 1840s and 1850s, the issue of accepting slavery split the nation's largest religious denominations (the Methodist, Baptist and Presbyterian churches) into separate Northern and Southern organizations see Methodist Episcopal Church, South, Southern Baptist Convention, and Presbyterian Church in the Confederate States of America).
Southern slaves generally attended their masters' white churches, where they often outnumbered the white congregants. They were usually permitted to sit only in the back or in the balcony. They listened to white preachers, who emphasized the obligation of slaves to keep in their place, and acknowledged the slave's identity as both person and property. Preachers taught the masters responsibility and the concept of appropriate paternal treatment, using Christianity to improve conditions for slaves, and to treat them "justly and fairly" (Col. 4:1). This included masters having self-control, not disciplining under anger, not threatening, and ultimately fostering Christianity among their slaves by example.
Slaves also created their own religious observances, meeting alone without the supervision of their white masters or ministers. The larger plantations with groups of slaves numbering twenty, or more, tended to be centers of nighttime meetings of one or several plantation slave populations. These congregations revolved around a singular preacher, often illiterate with limited knowledge of theology, who was marked by his personal piety and ability to foster a spiritual environment. African Americans developed a theology related to Biblical stories having the most meaning for them, including the hope for deliverance from slavery by their own Exodus. One lasting influence of these secret congregations is the African-American spiritual.
According to Herbert Aptheker, "there were few phases of ante-bellum Southern life and history that were not in some way influenced by the fear of, or the actual outbreak of, militant concerted slave action."
Historians in the 20th century identified 250 to 311 slave uprisings in U.S. and colonial history. Those after 1776, include:
In 1831, Nat Turner, a literate slave who claimed to have spiritual visions, organized a slave rebellion in Southampton County, Virginia; it was sometimes called the Southampton Insurrection. Turner and his followers killed nearly 60 white inhabitants, mostly women and children. Many of the men in the area were attending a religious event in North Carolina. Eventually Turner was captured with 17 other rebels, who were subdued by the militia. Turner and his followers were hanged, and Turner's body was flayed. In a frenzy of fear and retaliation, the militia killed more than 100 slaves who had not been involved in the rebellion. Planters whipped hundreds of innocent slaves to ensure resistance was quelled.
This rebellion prompted Virginia and other slave states to pass more restrictions on slaves and free people of color, controlling their movement and requiring more white supervision of gatherings. In 1835 North Carolina withdrew the franchise for free people of color, and they lost their vote.

Across the South, white legislatures enacted harsh new laws to curtail the already limited rights of African Americans. Virginia prohibited blacks, free or slave, from practicing preaching, prohibited blacks from owning firearms, and forbade anyone to teach slaves or free blacks how to read. It specified heavy penalties for both student and teacher if slaves were educated, including whippings or jail.
[E]very assemblage of negroes for the purpose of instruction in reading or writing, or in the night time for any purpose, shall be an unlawful assembly. Any justice may issue his warrant to any office or other person, requiring him to enter any place where such assemblage may be, and seize any negro therein; and he, or any other justice, may order such negro to be punished with stripes.
There were approximately 15,000 slaves in New England in 1770 of 650,000 inhabitants. 35,000 slaves live in the Mid-Atlantic States of 600,000 inhabitants of whom 19,000 lived in New York where they made up 11% of the population. By 1790 Virginia held 44% (315,000 in a total population of 750,000 the State). It was common in agriculture, with a more massive presence in the South – the region where climate was more propitious for widescale agricultural activity. By 1790 slavery in the New England States was abolished in Massachusetts, New Hampshire, and Vermont and phased out in Rhode Island and Connecticut. New York introduced gradual emancipation in 1799 (completed in 1827). Pennsylvania abolished slavery during the War for Independence.
Robert Fogel and Stanley Engerman, in their 1974 book Time on the Cross, argued that the rate of return of slavery at the market price was close to 10 percent, a number close to investment in other assets. The transition from indentured servants to slaves is cited to show that slaves offered greater profits to their owners. A qualified consensus among economic historians and economists is that "Slave agriculture was efficient compared with free agriculture. Economies of scale, effective management, and intensive utilization of labor and capital made southern slave agriculture considerably more efficient than nonslave southern farming", and it is the near-universal consensus among economic historians and economists that slavery was not "a system irrationally kept in existence by plantation owners who failed to perceive or were indifferent to their best economic interests".
The relative price of slaves and indentured servants in the antebellum period did decrease. Indentured servants became more costly with the increase in the demand of skilled labor in England. At the same time, slaves were mostly supplied from within the United States and thus language was not a barrier, and the cost of transporting slaves from one state to another was relatively low. However, as in Brazil and Europe, slavery at its end in the United States tended to be concentrated in the poorest regions of the United States, with a qualified consensus among economists and economic historians concluding that the "modern period of the South's economic convergence to the level of the North only began in earnest when the institutional foundations of the southern regional labor market were undermined, largely by federal farm and labor legislation dating from the 1930s."
In the decades preceding the Civil War, the black population of the United States experienced a rapid natural increase. Unlike the Arab slave trade with Africa, the slave population transported by the Atlantic slave trade to the United States was sex-balanced. The slave population multiplied nearly fourfold between 1810 and 1860, despite the passage of the Act Prohibiting Importation of Slaves signed into law by President Thomas Jefferson in 1807 banning the international slave trade. Thus, it is also the universal consensus among modern economic historians and economists that slavery in the United States was not "economically moribund on the eve of the Civil War". In the 2010s, several historians, among them Edward E. Baptist and Sven Beckert, have posited that slavery was integral in the development of American capitalism. Other economic historians have rejected that thesis.
Scholars disagree on how to quantify efficiency of slavery. In Time on the Cross, Fogel and Engerman equate efficiency to total factor productivity (TFP)—the output per average unit of input on a farm. Using this measurement, Southern farms that enslaved black people using the gang system were 35% more efficient than Northern farms which used free labor. Under the gang system, groups of slaves perform synchronized tasks under the constant vigilance of an overseer. Each group was like a part of a machine. If perceived to be working below his capacity, a slave could be punished. Fogel argues that this kind of negative enforcement was not frequent and that slaves and free laborers had similar quality of life; however, there is controversy on this last point. A critique of Fogel and Engerman's view was published by Paul A. David in 1976.
In 1995, a random survey of 178 members of the Economic History Association sought to study the views of economists and economic historians on the debate. The study found that 72 percent of economists and 65 percent of economic historians would generally agree that "Slave agriculture was efficient compared with free agriculture. Economies of scale, effective management, and intensive utilization of labor and capital made southern slave agriculture considerably more efficient than nonslave southern farming." 48 percent of the economists agreed without provisos, while 24 percent agreed when provisos were included in the statement. On the other hand, 58 percent of economic historians and 42 percent of economists disagreed with Fogel and Engerman's "proposition that the material (not psychological) conditions of the lives of slaves compared favorably with those of free industrial workers in the decades before the Civil War".
Controlling for inflation, prices of slaves rose dramatically in the six decades prior to Civil War, reflecting demand due to commodity cotton, as well as use of slaves in shipping and manufacturing. Although the prices of slaves relative to indentured servants declined, both got more expensive. Cotton production was rising and relied on the use of slaves to yield high profits. Fogel and Engeman initially argued that if the Civil War had not happened, the slave prices would have increased even more, an average of more than 50 percent by 1890.:96
Prices reflected the characteristics of the slave—such factors as sex, age, nature, and height were all taken into account to determine the price of a slave. Over the life-cycle, the price of enslaved women was higher than their male counterparts up to puberty age, as they would likely bear children and produce more slaves, in addition to serving as laborers. Men around the age of 25 were the most valued, as they were at the highest level of productivity and still had a considerable life-span. If slaves had a history of fights or escapes, their price was lowered reflecting what planters believed was risk of repeating such behavior. Slave traders and buyers would examine a slave's back for whipping scars—a large number of injuries would be seen as evidence of laziness or rebelliousness, rather than the previous master's brutality, and would lower the slave's price. Taller male slaves were priced at a higher level, as height was viewed as a proxy for fitness and productivity.
The conditions of the market led to shocks in the supply and demand of slaves, which in turn changed prices. For example, slaves became more expensive after 1808, when no more could be imported. The market for the products of their work also affected slaves' economic value: demand for slaves fell with the price of cotton in 1840. Anticipation of changes also had a huge influence on prices. As the Civil War progressed, there was great doubt that slavery would continue to be legal, and prime males in New Orleans were sold at $1,116 by 1862 as opposed to $1,381 in 1861.
While slavery brought profits in the short run, discussion continues on the economic benefits of slavery in the long run. In 1995, a random anonymous survey of 178 members of the Economic History Association found that out of the 40 propositions about American economic history that were surveyed, the group of propositions most disputed by economic historians and economists were those about the postbellum economy of the American South (along with the Great Depression). The only exception was the proposition initially put forward by historian Gavin Wright that the "modern period of the South's economic convergence to the level of the North only began in earnest when the institutional foundations of the southern regional labor market were undermined, largely by federal farm and labor legislation dating from the 1930s." 62 percent of economists (24 percent with and 38 percent without provisos) and 73 percent of historians (23 percent with and 50 percent without provisos) agreed with this statement. Wright has also argued that the private investment of monetary resources in the cotton industry, among others, delayed development in the South of commercial and industrial institutions. There was little public investment in railroads or other infrastructure. Wright argues that agricultural technology was far more developed in the South, representing an economic advantage of the South over the North of the United States.
In Democracy in America, Alexis de Tocqueville noted that "the colonies in which there were no slaves became more populous and more rich than those in which slavery flourished." Economists Peter H. Lindert and Jeffrey G. Williamson, in a pair of articles published in 2012 and 2013, found that, despite the American South initially having per capita income roughly double that of the North in 1774, incomes in the South had declined 27% by 1800 and continued to decline over the next four decades, while the economies in New England and the Mid-Atlantic states vastly expanded. By 1840, per capita income in the South was well behind the Northeast and the national average. (Note: This is also true of in the early 21st century.)
Lindert and Williamson argue that this antebellum period is an example of what economists Daron Acemoglu, Simon Johnson, and James A. Robinson call "a reversal of fortune". In his essay "The Real History of Slavery", economist Thomas Sowell reiterated and augmented the observation made by de Tocqueville by comparing slavery in the United States to slavery in Brazil. He notes that slave societies reflected similar economic trends in those and other parts of the world, suggesting that the trend Lindert and Williamson identify may have continued until the American Civil War:
Both in Brazil and in the United States—the countries with the two largest slave populations in the Western Hemisphere—the end of slavery found the regions in which slaves had been concentrated poorer than other regions of these same countries. For the United States, a case could be made that this was due to the Civil War, which did so much damage to the South, but no such explanation would apply to Brazil, which fought no Civil War over this issue. Moreover, even in the United States, the South lagged behind the North in many ways even before the Civil War. Although slavery in Europe died out before it was abolished in the Western Hemisphere, as late as 1776 slavery had not yet died out all across the continent when Adam Smith wrote in The Wealth of Nations that it still existed in some eastern regions. But, even then, Eastern Europe was much poorer than Western Europe. The slavery of North Africa and the Middle East, over the centuries, took more slaves from sub-Saharan Africa than the Western Hemisphere did… But these remained largely poor countries until the discovery and extraction of their vast oil deposits.
Sowell also notes in Ethnic America: A History, citing historians Clement Eaton and Eugene Genovese, that three-quarters of Southern white families owned no slaves at all. Most slaveholders lived on farms rather than plantations, and few plantations were as large as the fictional ones depicted in Gone with the Wind. In "The Real History of Slavery," Sowell also notes in comparison to slavery in the Arab world and the Middle East (where slaves were seldom used for productive purposes) and China (where the slaves consumed the entire output they created), Sowell observes that many commercial slaveowners in the antebellum South tended to be spendthrift and many lost their plantations due to creditor foreclosures, and in Britain, profits by British slave traders only amounted to 2 percent of British domestic investment in the 18th century. Sowell draws the following conclusion regarding the macroeconomic value of slavery:
In short, even though some individual slaveowners grew rich and some family fortunes were founded on the exploitation of slaves, that is very different from saying that the whole society, or even its non-slave population as a whole, was more economically advanced than it would have been in the absence of slavery. What this means is that, whether employed as domestic servants or producing crops or other goods, millions suffered exploitation and dehumanization for no higher purpose than the...aggrandizement of slaveowners.
Eric Hilt noted that while some historians have suggested slavery was necessary for the Industrial Revolution (on the grounds that American slave plantations produced most of the raw cotton for the British textiles market and the British textiles market was the vanguard of the Industrial Revolution), it is not clear if this is actually true; there is no evidence that cotton could not have been mass produced by yeoman farmers rather than slave plantations if the latter had not existed (as their existence tended to force yeoman farmers into subsistence farming) and there is some evidence that they certainly could have. The soil and climate of the American South were excellent for growing cotton, so it is not unreasonable to postulate that farms without slaves could have produced substantial amounts of cotton; even if they did not produce as much as the plantations did, it could still have been enough to serve the demand of British producers. Similar arguments have been made by other historians.
Scholar Adrienne Davis articulates how the economics of slavery also can be defined as a sexual economy, specifically focusing on how black women were expected to perform physical, sexual, and reproductive labor to provide a consistent enslaved workforce and increase the profits of white slavers. Davis writes that black women were needed for their “sexual and reproductive labor to satisfy the economic, political, and personal interest of white men of the elite class”  articulating that black women's reproductive capacity was important in the maintenance of the system of slavery due to its ability to perpetuate an enslaved workforce. She is also drawing attention to black women's labor being needed to maintain the aristocracy of a white ruling class, due to the intimate nature of reproduction and its potential for producing more enslaved peoples.
Due to the institution of partus sequitur ventrem, black women's wombs became the site where slavery was developed and transferred, meaning that black women were not only used for their physical labor, but for their sexual and reproductive labor as well.
"The rule that the children’s status follows their mothers’ was a foundational one for our economy. It converted enslaved women’s reproductive capacity into market capital"
This articulation by Davis illustrates how black women's reproductive capacity was commodified under slavery, and that an analysis of the economic structures of slavery requires an acknowledgment of how pivotal black women's sexuality was in maintaining slavery's economic power. Davis writes how black women performed labor under slavery, writing: “[black women were] male when convenient and horrifically female when needed” The fluctuating expectations of black women's gendered labor under slavery disrupted the white normative roles that were assigned to white men and white women. This ungendering black women received under slavery contributed to the systemic dehumanization experienced by enslaved black women, as they were unable to receive the expectations or experiences of either gender within the white binary.
Davis’ arguments addresses the fact that under slavery, black women's sexuality became linked to the economic and public sphere, making their intimate lives into public institutions. Black women's physical labor was gendered as masculine under slavery when they were needed to yield more profit, but their reproductive capacities and sexual labor was equally as important in maintaining white power over black communities and perpetuating an enslaved workforce. This blurring of the line between the private and public sphere is another way Davis articulates how black women's sexuality and reproduction was commodified and exploited for capitalist gain, as their private and intimate lives became disrupted by the violence at the hands of white men, and their sexual capacities became an important part of the public marketplace and United States economy.
Despite this, the slave population transported by the Atlantic slave trade to the United States was sex-balanced and most surviving the passage, because despite lacking legal recognition most slaves in the antebellum South lived in families, unlike the Arab slave trade with Africa which was overwhelmingly female and the majority died en route crossing the Sahara (with the large majority of the minority of male African slaves dying as a result of crude castration procedures to produce eunuchs in demand as harem attendants). Under Sharia, men were historically allowed to have sexual intercourse with any female slaves they owned. Additionally, cognitive scientist Steven Pinker in The Better Angels of Our Nature notes that despite the de jure abolitions of slavery by Islamic countries in the 20th century, the majority of the countries where human trafficking still occurs are Muslim-majority, while political scientists Valerie M. Hudson and Bradley Thayer have noted that Islam is the only major religious tradition that still allows polygyny.
In 1850, Congress passed the Fugitive Slave Act, which required law enforcement and citizens of free states to cooperate in the capture and return of slaves. This met with considerable overt and covert resistance in free states and cities such as Philadelphia, New York, and Boston. Refugees from slavery continued to flee the South across the Ohio River and other parts of the Mason–Dixon line dividing North from South, to the North and Canada via the Underground Railroad. Some white northerners helped hide former slaves from their former owners or helped them reach freedom in Canada.
As part of the Compromise of 1850, Congress abolished the slave trade (though not the ownership of slaves) in the District of Columbia; fearing this would happen, Alexandria, regional slave trading center and port, successfully sought its removal from the District of Columbia and devolution to Virginia. After 1854, Republicans argued that the "Slave Power", especially the pro-slavery Democratic Party in the South, controlled two of the three branches of the Federal government.
The abolitionists, realizing that the total elimination of slavery was as an immediate goal unrealistic, worked to prevent expansion of slavery into the western territories which eventually would be new states. The Missouri Compromise, the Compromise of 1850, and the Bleeding Kansas crisis dealt with whether new states would be slave or free, or how that was to be decided. Both sides were anxious about effects of these decisions on the balance of power in the Senate.
After the passage of the Kansas–Nebraska Act in 1854, border fighting broke out in Kansas Territory, where the question of whether it would be admitted to the Union as a slave or free state was left to the inhabitants. Migrants from free and slave states moved into the territory to prepare for the vote on slavery. Abolitionist John Brown was active in the fighting in "Bleeding Kansas," but so too were many white Southerners who opposed abolition.
Abraham Lincoln's and the Republicans' political platform in 1860 was to stop slavery's expansion. Historian James McPherson says that in a famous speech in 1858, Lincoln said American republicanism can be purified by restricting the further expansion of slavery as the first step to putting it on the road to 'ultimate extinction.' Southerners took Lincoln at his word. When he won the presidency they left the Union to escape the 'ultimate extinction' of slavery."
With the development of slave and free states after the American Revolution, and far-flung commercial and military activities, new situations arose in which slaves might be taken by masters into free states. Most free states not only prohibited slavery, but ruled that slaves brought and kept there illegally could be freed. Such cases were sometimes known as transit cases. Dred Scott and his wife Harriet Scott each sued for freedom in St. Louis after the death of their master, based on their having been held in a free territory (the northern part of the Louisiana Purchase from which slavery was excluded under the terms of the Missouri Compromise). (Later the two cases were combined under Dred Scott's name.) Scott filed suit for freedom in 1846 and went through two state trials, the first denying and the second granting freedom to the couple (and, by extension, their two daughters, who had also been held illegally in free territories). For 28 years, Missouri state precedent had generally respected laws of neighboring free states and territories, ruling for freedom in such transit cases where slaves had been held illegally in free territory. But in the Dred Scott case, the State Supreme Court ruled against the slaves.
After Scott and his team appealed the case to the U.S. Supreme Court, Chief Justice Roger B. Taney, in a sweeping decision, denied Scott his freedom. The 1857 decision, decided 7–2, held that a slave did not become free when taken into a free state; Congress could not bar slavery from a territory; and people of African descent imported into the United States and held as slaves, or their descendants, could never be citizens and thus had no status to bring suit in a U.S. court. A state could not bar slaveowners from bringing slaves into that state. Many Republicans, including Abraham Lincoln, considered the decision unjust and evidence that the Slave Power had seized control of the Supreme Court. Anti-slavery groups were enraged and slave owners encouraged, escalating the tensions that led to civil war.
The divisions became fully exposed with the 1860 presidential election. The electorate split four ways. The Southern Democrats endorsed slavery, while the Republicans denounced it. The Northern Democrats said democracy required the people to decide on slavery locally, state by state and territory by territory. The Constitutional Union Party said the survival of the Union was at stake and everything else should be compromised.
Lincoln, the Republican, won with a plurality of popular votes and a majority of electoral votes. Lincoln, however, did not appear on the ballots of ten southern slave states. Many slave owners in the South feared that the real intent of the Republicans was the abolition of slavery in states where it already existed, and that the sudden emancipation of four million slaves would be disastrous for the slave owners and for the economy that drew its greatest profits from the labor of people who were not paid. The slave owners feared that ending the balance could lead to the domination of the federal government by the northern free states. This led seven southern states to secede from the Union. When the southern forces attacked a US Army installation at Fort Sumter, the American Civil War began and four additional slave states seceded. Northern leaders had viewed the slavery interests as a threat politically, but with secession, they viewed the prospect of a new Southern nation, the Confederate States of America, with control over the Mississippi River and parts of the West, as politically unacceptable. Most of all they could not accept this repudiation of American nationalism.
The consequent American Civil War, beginning in 1861, led to the end of chattel slavery in America. Not long after the war broke out, through a legal maneuver credited to Union General Benjamin F. Butler, a lawyer by profession, slaves who came into Union "possession" were considered "contraband of war". General Butler ruled that they were not subject to return to Confederate owners as they had been before the war. Soon word spread, and many slaves sought refuge in Union territory, desiring to be declared "contraband". Many of the "contrabands" joined the Union Army as workers or troops, forming entire regiments of the U.S. Colored Troops. Others went to refugee camps such as the Grand Contraband Camp near Fort Monroe or fled to northern cities. General Butler's interpretation was reinforced when Congress passed the Confiscation Act of 1861, which declared that any property used by the Confederate military, including slaves, could be confiscated by Union forces.
At the beginning of the war, some Union commanders thought they were supposed to return escaped slaves to their masters. By 1862, when it became clear that this would be a long war, the question of what to do about slavery became more general. The Southern economy and military effort depended on slave labor. It began to seem unreasonable to protect slavery while blockading Southern commerce and destroying Southern production. As Congressman George W. Julian of Indiana put it in an 1862 speech in Congress, the slaves "cannot be neutral. As laborers, if not as soldiers, they will be allies of the rebels, or of the Union." Julian and his fellow Radical Republicans put pressure on Lincoln to rapidly emancipate the slaves, whereas moderate Republicans came to accept gradual, compensated emancipation and colonization. Copperheads, the border states and War Democrats opposed emancipation, although the border states and War Democrats eventually accepted it as part of total war needed to save the Union.
The Emancipation Proclamation was an executive order issued by President Lincoln on January 1, 1863. In a single stroke it changed the legal status, as recognized by the U.S. government, of 3 million slaves in designated areas of the Confederacy from "slave" to "free". It had the practical effect that as soon as a slave escaped the control of the Confederate government, by running away or through advances of federal troops, the slave became legally and actually free. Plantation owners, realizing that emancipation would destroy their economic system, sometimes moved their slaves as far as possible out of reach of the Union army. By June 1865, the Union Army controlled all of the Confederacy and had liberated all of the designated slaves.
In 1861, Lincoln expressed the fear that premature attempts at emancipation would mean the loss of the border states. He believed that "to lose Kentucky is nearly the same as to lose the whole game." At first, Lincoln reversed attempts at emancipation by Secretary of War Simon Cameron and Generals John C. Fremont (in Missouri) and David Hunter (in South Carolina, Georgia and Florida) to keep the loyalty of the border states and the War Democrats.
Lincoln mentioned his Emancipation Proclamation to members of his cabinet on July 21, 1862. Secretary of State William H. Seward told Lincoln to wait for a victory before issuing the proclamation, as to do otherwise would seem like "our last shriek on the retreat". In September 1862 the Battle of Antietam provided this opportunity, and the subsequent War Governors' Conference added support for the proclamation. Lincoln had already published a letter encouraging the border states especially to accept emancipation as necessary to save the Union. Lincoln later said that slavery was "somehow the cause of the war".
Lincoln issued his preliminary Emancipation Proclamation on September 22, 1862, and said that a final proclamation would be issued if his gradual plan, based on compensated emancipation and voluntary colonization, was rejected. Only the District of Columbia accepted Lincoln's gradual plan, and Lincoln issued his final Emancipation Proclamation on January 1, 1863. In his letter to Hodges, Lincoln explained his belief that
If slavery is not wrong, nothing is wrong … And yet I have never understood that the Presidency conferred upon me an unrestricted right to act officially upon this judgment and feeling … I claim not to have controlled events, but confess plainly that events have controlled me.
Lincoln's Emancipation Proclamation of January 1, 1863 was a powerful action that promised freedom for slaves in the Confederacy as soon as the Union armies reached them, and authorized the enlistment of African Americans in the Union Army. The Emancipation Proclamation did not free slaves in the Union-allied slave-holding states that bordered the Confederacy. Since the Confederate States did not recognize the authority of President Lincoln, and the proclamation did not apply in the border states, at first the proclamation freed only those slaves who had escaped behind Union lines. The proclamation made the abolition of slavery an official war goal that was implemented as the Union took territory from the Confederacy. According to the Census of 1860, this policy would free nearly four million slaves, or over 12% of the total population of the United States.
Based on the President's war powers, the Emancipation Proclamation applied to territory held by Confederates at the time. However, the Proclamation became a symbol of the Union's growing commitment to add emancipation to the Union's definition of liberty. Lincoln played a leading role in getting the constitutionally-required two-thirds majority of both houses of Congress to vote for the Thirteenth Amendment, which made emancipation universal and permanent.
Enslaved African Americans had not waited for Lincoln before escaping and seeking freedom behind Union lines. From early years of the war, hundreds of thousands of African Americans escaped to Union lines, especially in Union-controlled areas such as Norfolk and the Hampton Roads region in 1862 Virginia, Tennessee from 1862 on, the line of Sherman's march, etc. So many African Americans fled to Union lines that commanders created camps and schools for them, where both adults and children learned to read and write. The American Missionary Association entered the war effort by sending teachers south to such contraband camps, for instance, establishing schools in Norfolk and on nearby plantations.
In addition, nearly 200,000 African-American men served with distinction in the Union forces as soldiers and sailors. Most were escaped slaves. The Confederacy was outraged by armed black soldiers and refused to treat them as prisoners of war. They murdered many, as at the Fort Pillow Massacre, and re-enslaved others.
The Arizona Organic Act abolished slavery on February 24, 1863 in the newly formed Arizona Territory. Tennessee and all of the border states (except Kentucky) abolished slavery by early 1865. Thousands of slaves were freed by the operation of the Emancipation Proclamation as Union armies marched across the South. Emancipation came to the remaining southern slaves after the surrender of all Confederate troops in spring 1865.
In spite of the South's shortage of manpower, until 1865, most Southern leaders opposed arming slaves as soldiers. However, a few Confederates discussed arming slaves. Finally in early 1865 General Robert E. Lee said black soldiers were essential, and legislation was passed. The first black units were in training when the war ended in April.
As the great day drew nearer, there was more singing in the slave quarters than usual. It was bolder, had more ring, and lasted later into the night. Most of the verses of the plantation songs had some reference to freedom.... Some man who seemed to be a stranger (a United States officer, I presume) made a little speech and then read a rather long paper—the Emancipation Proclamation, I think. After the reading we were told that we were all free, and could go when and where we pleased. My mother, who was standing by my side, leaned over and kissed her children, while tears of joy ran down her cheeks. She explained to us what it all meant, that this was the day for which she had been so long praying, but fearing that she would never live to see.
The war ended on June 22, 1865, and following that surrender, the Emancipation Proclamation was enforced throughout remaining regions of the South that had not yet freed the slaves. Slavery officially continued for a couple of months in other locations. Federal troops arrived in Galveston, Texas on June 19, 1865, to enforce the emancipation. That day of gaining freedom in Texas is now celebrated as Juneteenth in many U.S. states.
The Thirteenth Amendment, abolishing slavery except as punishment for a crime, had been passed by the Senate in April 1864, and by the House of Representatives in January 1865. The amendment did not take effect until it was ratified by three fourths of the states, which occurred on December 6, 1865, when Georgia ratified it. On that date, all remaining slaves became officially free.
Legally, the last 40,000–45,000 slaves were freed in the last two slave states of Kentucky and Delaware by the final ratification of the Thirteenth Amendment to the Constitution on December 18, 1865. Slaves still held in Tennessee, Kentucky, Kansas, New Jersey, Delaware, West Virginia, Maryland, Missouri, Washington, D.C., and twelve parishes of Louisiana also became legally free on this date.
The American historian R.R. Palmer opined that the abolition of slavery in the United States without compensation to the former slave owners was an "annihilation of individual property rights without parallel...in the history of the Western world". Economic historian Robert E. Wright argues that it would have been much cheaper, with minimal deaths, if the federal government had purchased and freed all the slaves, rather than fighting the Civil War. Another economic historian, Roger Ransom, writes that Gerald Gunderson compared compensated emancipation to the cost of the war and "notes that the two are roughly the same order of magnitude — 2.5 to 3.7 billion dollars". Ransom also writes that compensated emancipation would have tripled federal outlays if paid over the period of 25 years and was a program that had no political support within the United States during the 1860s.
Journalist Douglas A. Blackmon reported in his Pulitzer Prize-winning book Slavery By Another Name that many blacks were virtually enslaved under convict leasing programs, which started after the Civil War. Most Southern states had no prisons; they leased convicts to businesses and farms for their labor, and the lessee paid for food and board. The incentives for abuse were satisfied.
The continued involuntary servitude took various forms, but the primary forms included convict leasing, peonage, and sharecropping, with the latter eventually encompassing poor whites as well. By the 1930s, whites constituted most of the sharecroppers in the South. Mechanization of agriculture had reduced the need for farm labor, and many blacks left the South in the Great Migration. Jurisdictions and states created fines and sentences for a wide variety of minor crimes, and used these as an excuse to arrest and sentence blacks. Under convict leasing programs, African American men, often guilty of no crime at all, were arrested, compelled to work without pay, repeatedly bought and sold, and coerced to do the bidding of the leaseholder. Sharecropping, as it was practiced during this period, often involved severe restrictions on the freedom of movement of sharecroppers, who could be whipped for leaving the plantation. Both sharecropping and convict leasing were legal and tolerated by both the north and south. However, peonage was an illicit form of forced labor. Its existence was ignored by authorities while thousands of African Americans and poor Anglo Americans were subjugated and held in bondage until the mid 1960s to the late 1970s. With the exception of cases of peonage, beyond the period of Reconstruction, the federal government took almost no action to enforce the 13th Amendment until December 1941 when President Franklin Delano Roosevelt summoned his attorney general. Five days after Pearl Harbor, at the request of the president Attorney General Francis Biddle issued Circular No. 3591 to all federal prosecutors, instructing them to actively investigate and try any case of involuntary servitude or slavery. Several months later, convict leasing was officially abolished. But aspects have persisted in other forms, while historians argue that other systems of penal labor, were all created in 1865 and convict leasing was simply the most oppressive form. Over time a large civil rights movement arose to bring full civil rights and equality under the law to all Americans. 
With emancipation a legal reality, white Southerners were concerned with both controlling the newly freed slaves and keeping them in the labor force at the lowest level. The system of convict leasing began during Reconstruction and was fully implemented in the 1880s and officially ending in the last state, Alabama, in 1928. It persisted in various forms until it was abolished in 1942 by President Franklin D. Roosevelt during World War II, several months after the attack on Pearl Harbor involved the U.S. in the conflict. This system allowed private contractors to purchase the services of convicts from the state or local governments for a specific time period. African Americans, due to "vigorous and selective enforcement of laws and discriminatory sentencing," made up the vast majority of the convicts leased. Writer Douglas A. Blackmon writes of the system:
It was a form of bondage distinctly different from that of the antebellum South in that for most men, and the relatively few women drawn in, this slavery did not last a lifetime and did not automatically extend from one generation to the next. But it was nonetheless slavery – a system in which armies of free men, guilty of no crimes and entitled by law to freedom, were compelled to labor without compensation, were repeatedly bought and sold, and were forced to do the bidding of white masters through the regular application of extraordinary physical coercion.
The anti-literacy laws after 1832 contributed greatly to the problem of widespread illiteracy facing the freedmen and other African Americans after Emancipation and the Civil War 35 years later. The problem of illiteracy and need for education was seen as one of the greatest challenges confronting these people as they sought to join the free enterprise system and support themselves during Reconstruction and thereafter.
Consequently, many black and white religious organizations, former Union Army officers and soldiers, and wealthy philanthropists were inspired to create and fund educational efforts specifically for the betterment of African Americans; some African Americans had started their own schools before the end of the war. Northerners helped create numerous normal schools, such as those that became Hampton University and Tuskegee University, to generate teachers, as well as other colleges for former slaves. Blacks held teaching as a high calling, with education the first priority for children and adults. Many of the most talented went into the field. Some of the schools took years to reach a high standard, but they managed to get thousands of teachers started. As W. E. B. Du Bois noted, the black colleges were not perfect, but "in a single generation they put thirty thousand black teachers in the South" and "wiped out the illiteracy of the majority of black people in the land".
Northern philanthropists continued to support black education in the 20th century, even as tensions rose within the black community, exemplified by Booker T. Washington and W. E. B. Du Bois, as to the proper emphasis between industrial and classical academic education at the college level. An example of a major donor to Hampton Institute and Tuskegee was George Eastman, who also helped fund health programs at colleges and in communities. Collaborating with Washington in the early decades of the 20th century, philanthropist Julius Rosenwald provided matching funds for community efforts to build rural schools for black children. He insisted on white and black cooperation in the effort, wanting to ensure that white-controlled school boards made a commitment to maintain the schools. By the 1930s local parents had helped raise funds (sometimes donating labor and land) to create over 5,000 rural schools in the South. Other philanthropists, such as Henry H. Rogers and Andrew Carnegie, each of whom had arisen from modest roots to become wealthy, used matching fund grants to stimulate local development of libraries and schools.
On February 24, 2007, the Virginia General Assembly passed House Joint Resolution Number 728 acknowledging "with profound regret the involuntary servitude of Africans and the exploitation of Native Americans, and call for reconciliation among all Virginians". With the passing of this resolution, Virginia became the first state to acknowledge through the state's governing body their state's negative involvement in slavery. The passing of this resolution was in anticipation of the 400th anniversary commemoration of the founding of Jamestown, Virginia (the first permanent English settlement in North America), which was an early colonial slave port. Apologies have also been issued by Alabama, Florida, Maryland, North Carolina and New Jersey.
On July 29, 2008, during the 110th United States Congress session, the United States House of Representatives passed a resolution 'HR. 194' apologizing for American slavery and subsequent discriminatory laws.
The U.S. Senate unanimously passed a similar resolution on June 18, 2009, apologizing for the "fundamental injustice, cruelty, brutality, and inhumanity of slavery". It also explicitly states that it cannot be used for restitution claims.
A 2016 study, published in The Journal of Politics, finds that "Whites who currently live in Southern counties that had high shares of slaves in 1860 are more likely to identify as a Republican, oppose affirmative action, and express racial resentment and colder feelings toward blacks." The study contends that "contemporary differences in political attitudes across counties in the American South in part trace their origins to slavery's prevalence more than 150 years ago. " The authors argue that their findings are consistent with the theory that "following the Civil War, Southern whites faced political and economic incentives to reinforce existing racist norms and institutions to maintain control over the newly freed African American population. This amplified local differences in racially conservative political attitudes, which in turn have been passed down locally across generations."
A 2017 study in the British Journal of Political Science argued that the British American colonies without slavery adopted better democratic institutions in order to attract migrant workers to their colonies.
During the 17th and 18th centuries, Indian slavery, the enslavement of Native Americans by European colonists, was common. Many of these Native slaves were exported to the Northern colonies and to off-shore colonies, especially the "sugar islands" of the Caribbean. The exact number of Native Americans who were enslaved is unknown because vital statistics and census reports were at best infrequent. Historian Alan Gallay estimates that from 1670 to 1715, British slave traders sold between 24,000 and 51,000 Native Americans from what is now the southern part of the U.S. Andrés Reséndez estimates that between 147,000 and 340,000 Native Americans were enslaved in North America, excluding Mexico. Even after the Indian Slave Trade ended in 1750 the enslavement of Native Americans continued in the west, and also in the Southern states mostly through kidnappings.
Slavery of Native Americans was organized in colonial and Mexican California through Franciscan missions, theoretically entitled to ten years of Native labor, but in practice maintaining them in perpetual servitude, until their charge was revoked in the mid-1830s. Following the 1847–48 invasion by U.S. troops, the "loitering or orphaned Indians" were de facto enslaved in the new state from statehood in 1850 to 1867. Slavery required the posting of a bond by the slave holder and enslavement occurred through raids and a four-month servitude imposed as a punishment for Indian "vagrancy".
After 1800, some of the Cherokee and the other four civilized tribes of the Southeast started buying and using black slaves as labor. They continued this practice after removal to Indian Territory in the 1830s, when as many as 15,000 enslaved blacks were taken with them.
The nature of slavery in Cherokee society often mirrored that of white slave-owning society. The law barred intermarriage of Cherokees and enslaved African Americans, but Cherokee men had unions with enslaved women, resulting in mixed-race children. Cherokee who aided slaves were punished with one hundred lashes on the back. In Cherokee society, persons of African descent were barred from holding office even if they were also racially and culturally Cherokee. They were also barred from bearing arms and owning property. The Cherokee prohibited teaching African Americans to read and write.
By contrast, the Seminole welcomed into their nation African Americans who had escaped slavery (Black Seminoles). Historically, the Black Seminoles lived mostly in distinct bands near the Native American Seminole. Some were held as slaves of particular Seminole leaders. Seminole practice in Florida had acknowledged slavery, though not the chattel slavery model common elsewhere. It was, in fact, more like feudal dependency and taxation. The relationship between Seminole blacks and natives changed following their relocation in the 1830s to territory controlled by the Creek who had a system of chattel slavery. Pro slavery pressure from Creek and pro-Creek Seminole and slave raiding led to many Black Seminoles escaping to Mexico.
The Haida and Tlingit Indians who lived along southeast Alaska's coast were traditionally known as fierce warriors and slave-traders, raiding as far as California. Slavery was hereditary after slaves were taken as prisoners of war. Among some Pacific Northwest tribes, about a quarter of the population were slaves. Other slave-owning tribes of North America were, for example, Comanche of Texas, Creek of Georgia, the fishing societies, such as the Yurok, that lived along the coast from what is now Alaska to California; the Pawnee, and Klamath.
Some tribes held people as captive slaves late in the 19th century. For instance, "Ute Woman", was a Ute captured by the Arapaho and later sold to a Cheyenne. She was kept by the Cheyenne to be used as a prostitute to serve American soldiers at Cantonment in the Indian Territory. She lived in slavery until about 1880. She died of a hemorrhage resulting from "excessive sexual intercourse".
Slave owners included people of African ancestry, in each of the original Thirteen Colonies and all later states and territories that allowed slavery; in some cases black Americans owned white indentured servants. An African former indentured servant who settled in Virginia in 1621, Anthony Johnson, became one of the earliest documented slave owners in the mainland American colonies when he won a civil suit for ownership of John Casor. In 1830 there were 3,775 such black slaveholders in the South who owned a total of 12,760 slaves, a small percent, out of a total of over 2 million slaves. 80% of the black slaveholders were located in Louisiana, South Carolina, Virginia, and Maryland.
There were economic and ethnic differences between free blacks of the Upper South and Deep South, with the latter fewer in number, but wealthier and typically of mixed race. Half of the black slaveholders lived in cities rather than the countryside, with most living in New Orleans and Charleston. Especially New Orleans had a large, relatively wealthy free black population (gens de couleur) composed of people of mixed race, who had become a third social class between whites and enslaved blacks, under French and Spanish colonial rule. Relatively few non-white slaveholders were "substantial planters". Of those who were, most were of mixed race, often endowed by white fathers with some property and social capital. For example, Andrew Durnford of New Orleans was listed as owning 77 slaves. According to Rachel Kranz: "Durnford was known as a stern master who worked his slaves hard and punished them often in his efforts to make his Louisiana sugar plantation a success." In the years leading up to the Civil War, Antoine Dubuclet, who owned over a hundred slaves, was considered the wealthiest black slave owner in Louisiana.
The historians John Hope Franklin and Loren Schweninger wrote:
A large majority of profit-oriented free black slaveholders resided in the Lower South. For the most part, they were persons of mixed racial origin, often women who cohabited or were mistresses of white men, or mulatto men ... Provided land and slaves by whites, they owned farms and plantations, worked their hands in the rice, cotton, and sugar fields, and like their white contemporaries were troubled with runaways.
The historian Ira Berlin wrote:
In slave societies, nearly everyone—free and slave—aspired to enter the slaveholding class, and upon occasion some former slaves rose into slaveholders' ranks. Their acceptance was grudging, as they carried the stigma of bondage in their lineage and, in the case of American slavery, color in their skin.
African-American history and culture scholar Henry Louis Gates Jr. wrote:
... the percentage of free black slave owners as the total number of free black heads of families was quite high in several states, namely 43 percent in South Carolina, 40 percent in Louisiana, 26 percent in Mississippi, 25 percent in Alabama and 20 percent in Georgia.
Free blacks were perceived "as a continual symbolic threat to slaveholders, challenging the idea that 'black' and 'slave' were synonymous". Free blacks were sometimes seen as potential allies of fugitive slaves and "slaveholders bore witness to their fear and loathing of free blacks in no uncertain terms." For free blacks, who had only a precarious hold on freedom, "slave ownership was not simply an economic convenience but indispensable evidence of the free blacks' determination to break with their slave past and their silent acceptance – if not approval – of slavery."
The historian James Oakes in 1982 stated that "[t]he evidence is overwhelming that the vast majority of black slaveholders were free men who purchased members of their families or who acted out of benevolence". After 1810 Southern states made it increasingly difficult for any slaveholders to free slaves. Often the purchasers of family members were left with no choice but to maintain, on paper, the owner–slave relationship. In the 1850s "there were increasing efforts to restrict the right to hold bondsmen on the grounds that slaves should be kept 'as far as possible under the control of white men only.'"
In his 1985 statewide study of black slaveholders in South Carolina, Larry Koger challenged this benevolent view. He found that the majority of black slaveholders appeared to hold at least some of their slaves for commercial reasons. For instance, he noted that in 1850 more than 80 percent of black slaveholders were of mixed race, but nearly 90 percent of their slaves were classified as black. Koger also noted that many South Carolina free blacks operated small businesses as skilled artisans, and many owned slaves working in those businesses. "Koger emphasizes that it was all too common for freed slaves to become slaveholders themselves." There is a partial parallel in the discriminatory treatment of Africans by freed American slaves in Liberia,
Some free black slaveholders in New Orleans offered to fight for Louisiana in the Civil War. Over a thousand free black people volunteered and formed the 1st Louisiana Native Guard (CSA), which was disbanded without seeing combat.
Barbary pirates from North Africa began to seize North American colonists as early as 1625, and roughly 700 Americans were held captive in this region as slaves between 1785 and 1815. Some captives used their experiences as a North African slave to criticize slavery in the United States, such as William Ray in his book Horrors of Slavery.
The Barbary situation led directly to the creation of the United States Navy in March 1794. While the United States managed to secure peace treaties, these obliged it to pay tribute for protection from attack. Payments in ransom and tribute to the Barbary states amounted to 20% of United States government annual expenditures in 1800. The First Barbary War in 1801 and the Second Barbary War in 1815 led to more favorable peace terms ending the payment of tribute.

For various reasons, the census did not always include all of the slaves, especially in the West. California was admitted as a free state and reported no slaves. However, there were many slaves that were brought to work in the mines during the California Gold Rush. Some Californian communities openly tolerated slavery, such as San Bernardino, which was mostly made up of transplants from the neighboring slave territory of Utah. New Mexico Territory never reported any slaves on the census, yet sued the government for compensation for 600 slaves that were freed when congress outlawed slavery in the territory. Utah was actively trying to hide its slave population from Congress and did not report slaves in several communities. Additionally, the census did not traditionally include Native Americans, and hence did not include Native American slaves or black slaves owned by Native Americans. There were hundreds of Native American slaves in California, Utah and New Mexico that were never recorded in the census.

The historian Peter Kolchin, writing in 1993, noted that until the latter decades of the 20th century, historians of slavery had primarily concerned themselves with the culture, practices and economics of the slaveholders, not with the slaves. This was in part due to the circumstance that most slaveholders were literate and left behind written records, whereas slaves were largely illiterate and not in a position to leave written records. Scholars differed as to whether slavery should be considered a benign or a "harshly exploitive" institution.
Much of the history written prior to the 1950s had a distinctive racist slant to it. By the 1970s and 1980s, historians were using archaeological records, black folklore, and statistical data to develop a much more detailed and nuanced picture of slave life. Individuals were shown to have been resilient and somewhat autonomous in many of their activities, within the limits of their situation and despite its precariousness. Historians who wrote in this era include John Blassingame (Slave Community), Eugene Genovese (Roll, Jordan, Roll), Leslie Howard Owens (This Species of Property), and Herbert Gutman (The Black Family in Slavery and Freedom).
Arrival of "20 and odd" Africans in late August 1619, not aboard a Dutch ship as reported by John Rolfe, but an English warship, White Lion, sailing with a letters of marque issued to the British Captain Jope by the Protestant Dutch Prince Maurice, son of William of Orange. A letters of marque legally permitted the White Lion to sail as a privateer attacking any Spanish or Portuguese ships it encountered. The 20 and odd Africans were captives removed from the Portuguese slave ship, San Juan Bautista, following an encounter the ship had with the White Lion and her consort, the Treasurer, another British ship, while attempting to deliver its African prisoners to Mexico. Rolfe's reporting the White Lion as a Dutch warship was a clever ruse to transfer blame away from the British for piracy of the slave ship to the Dutch.
Nearing her destination, the slave ship was attacked by two English privateers, the White Lion and the Treasurer, in the Gulf of Mexico and robbed of 50–60 Africans.
