Angola was a prosperous community:232 of up to 750 maroons (escaped slaves):71 that existed in Florida from 1812:72 until Florida became a U.S. territory in 1821, at which point it was destroyed. The location was along the Manatee River in Bradenton, Florida, near Manatee Mineral Springs Park. The exact location is expansive, ranging from where the Braden River meets the Manatee River down to Sarasota Bay; archaeological research focuses on the Manatee Mineral Spring—a source of fresh water and later the location of the Village of Manatee two decades after the destruction of the maroon community. Archaeological evidence has been found and the archaeology report by Uzi Baram is on file with the Florida Division of Historical Resources of the Florida Department of State.
Spanish Florida was a haven for escaped slaves and for Native Americans deprived of their traditional lands during colonial times and in the first decades of U.S. independence. The underground railroad ran south during this period. Escaped slaves were welcomed into Florida by Spain, who granted freedom to slaves that converted to Catholicism. Under heavy U.S. pressure, Spain rescinded this welcome, but the change had little practical effect. Occupied with the Napoleonic War and with many colonies in revolt or close to revolt, Spain had neither the resources nor the inclination to capture and return escaped slaves. At one point, Spain invited the slaveowners to recapture them themselves.
There autonomous black communities developed in Spanish Florida, though not simultaneously. Fort Mose was the first and smallest autonomous black community but it was abandoned in 1763 when the British took over Florida. Fort Mose was heavily influenced by neighboring St. Augustine. The second community was at Prospect Bluff on the Apalachicola River but it was destroyed by forces under the command of General Andrew Jackson in 1816. Angola, farthest from the border of Georgia, was the last of the black settlements to survive. According to historian Canter Brown, Jr., "Most maroon settlements were tiny because people needed to escape detection. Angola's 600 to 750 people was an incredible size back then, and shows that these were capable people.":73 He described it as "one of the most significant historical sites in Florida and perhaps the U.S.":71
None of these were settled as a group, as white colonies were; refugees gradually accumulated over many years until a community of several hundred existed. Some refugees from the Negro Fort calamity came to Angola,:5 as did refugees from Lake Miccosukee Village and the Battle of Suwanee.
When Andrew Jackson became Florida's de facto territorial governor in 1821, and "acting in direct defiance of Secretary of War John C. Calhoun, Jackson's first order of business was to send his Creek allies on a search and destroy mission against Angola",:250 which was "burned to the ground".:73 The result of the raid was "terror" all over Florida and all the blacks who could left for the Bahamas.:250–252
