Best Answer: Many different tribes, the original slaves brought over by the Portuguese and sold to the Spanish came from the Congo and Angolan regions of central Africa, the Windward Coast and Senegambia to the north. When the British conquered Jamaica the slaves were set free and settled in the interior. They were known as the Maroons and guarded their freedom so fiercely that the British made treaties with them. Those brought in by the British came mostly from west Africa, the Gold Coast and Windward Coast. While some will have been from the local tribes (apparently kidnapping by unscrupulous traders was common) others will have been captives from raids into the interior.
Beginning in the late 17th century, Jamaican Maroons fought British colonists to a draw and eventually signed treaties in the 18th century that effectively freed them over 50 years before the abolition of the slave trade in 1807.hey eventually rose to leadership of the Mosquito Coast, and led extensive slave raids against Spanish-held territories in the first half of the 18th century. A third group were the Garifuna, who were actually maroons on the island of Saint Vincent deported to the coast of Honduras in 1797.
