Answer:
African tribes involved in the Atlantic slave trade.
Explanation:
The slavery system had existed before the arrival of European in Africa. According to some historians, slavery practised in different tribes in the west and central region of Africa. The existence of various ethnic group led to conflicts between themselves that produced captives who could become part of a local slave trade system. The pattern of the trade changes with the shipping of slaves in America. Europeans took advantage of the remaining slave system in Africa to obtain the labour for a plantation economy in the New World.
The Middle Passage was a stage of the Triangular Trade that connected three continents. Europe took manufactured goods and material to Africa in exchange for African slaves from local African leaders. The enslaved African came in America as labours to work in fields in the Southern colonies. Slaves sold to their buyer in return for raw materials for industries in England like cotton, indigo, etc.
