Colonial times saw the emergence of local law enforcement squads. In the North, these were the watchmen, who were paid small fees by private citizens to police the streets and maintain order in small areas. The first groups in the south were slave patrols, which were made up of slave owners and non-slave owners, and were also paid by private citizens. However, the parcels of land in the south were much larger, and therefore much less easy to patrol. Groups that focused on slave hunting were most prevalent in the south, as the majority of slave owners resided there. Contrary to popular belief, slave patrols were not composed solely of men. Women who owned slaves also took part, but no case of free blacks hunting slaves were recorded in the United States.

These southern law enforcement groups were created out of a need to maintain order among slaves and slave owners, rather than to protect the interests of the common, non-slaveholding people. Many southern slave owners were considered irresponsible if their charges were allowed to escape, and it was a fear that more slaves would upend the system if not met with retribution. It was in the general interest of all slaveholders to maintain discipline so that slaves did not have the chance to start an uprising.
The very first slave patrollers began their work in the Caribbean during the sixteenth and seventeenth centuries. They were primarily English and Spanish colonists who volunteered in order to keep a handle on the growing numbers of slaves. They were not terribly successful, as their territories were large and difficult to police. Consequently, many slaves were able to escape to the north where abolitionists and local governments sheltered them.
Many states allowed local law enforcement to enlist the help of federal marshals, U.S. commissioners, and other local citizens. This spread to more states with the ratification of the Fugitive Slave Act of 1850, which required all citizens to aid in the capture of runaway slaves. This meant that northerners and abolitionists were forced to comply with slave hunters, although they often found ways around the policy. Up until this point, many states did their best to thwart slave catchers by passing decrees such as Massachusetts’s personal liberty statute of 1842, which barred slave catchers from seeking the aid of state officials. However, the Fugitive Slave Act nullified these formal efforts, and abolitionists were forced to resort to small acts of defiance instead. In many areas it could actually be dangerous to be a part of the slave catching groups due to the immediate environment and the temperament of the locals.
Under the Fugitive Slave Act of 1850, slave hunters could easily obtain an order of removal, which allowed the return of a runaway slave. However, these orders were often met with resistance from northern abolitionists, who tried to intervene by blocking entry to the room where a fugitive was being held. Local government tried to shut this practice down by offering law enforcement agents a greater reward for returning a slave to the south than they could get from abolitionists who were willing to pay police to look the other way.
During the Civil War, these law enforcement groups met great difficulty, primarily because most of the white men were off fighting in the war. With the men gone, the duty to keep slaves in line fell on the women, who also had households to run. Lack of punishment and a greater likelihood of successful escape caused more and more slaves to run away. With slave patrols stretched so thinly, many slaves were able to escape, and were often aided by enemy invaders. Many of the slaves joined Union ranks, taking up arms against their former masters.
In the southern states, any person could capture an escaped slave and turn them over to law enforcement to receive compensation, and slaveowners could also put out advertisements promising a reward for anyone who captured their slaves. Slaveowners also hired people who made a living catching fugitive slaves. Since these slave catchers charged by the day and mile, many of them would travel long distances to hunt for fugitives. Slave catchers often used tracking dogs to sniff out their targets; these were called "negro dogs," and, though they could be of multiple breeds, they were typically bloodhounds. During the 1800s.
However, hiring people to catch slaves tended to only be effective if the slave catcher was in close proximity, as if they were not, they would have less of a chance of staying on the escaped slave's trail. Slaves reaching the northern states made a slave catcher's job substantially more difficult, as even if they did find the fugitive they were likely to face resistance from anti-slavery citizens. If a slave managed to escape this far, slave owners typically sent an agent more closely connected to them, or put out notices about the escaped slave.
White abolitionists from the North and anyone else aiding in freeing or hiding of slaves were punished for their efforts. One account of drastic fugitive slave catching was approximately 200 U.S. Marines escorting one fugitive slave back into the custody of his owner. As laws even in the North punished both the people who helped slaves escape as well as the fugitive slaves, many fled to Canada where slavery has remained illegal since 1833.
By the passage of the Fugitive Slave Act of 1850, slave catchers' jobs were made easier by the mandating of government officials to locate and prosecute runaway slaves, giving slave catchers more freedom to act under the law. With this law, slave catchers were reportedly able to gain warrants to apprehend those identified as fugitive slaves.

With the North becoming increasingly opposed to the idea of fugitive slave catchers they adopted "anti-southern" views. Several northern states passed new personal liberty laws in defiance of the South's efforts to have slaves captured and returned. Slave-catching was allowed in the North and the new laws in the North did not make it impossible to catch fugitive slaves. However, it became so difficult, expensive, and time-consuming that the fugitive slave catchers and the owners stopped trying.
The Fugitive Slave Act strengthened abolitionist response against slave catchers, with abolitionist groups including the Free Soil Party advocating for the use of firearms to stop slave catchers and kidnappers, comparing it to the American Revolution. The 1850's saw a significant rise in violent conflicts between abolitionists and law enforcement, with large groups forming to counter activities that threatened fugitive slaves.
