Answer:
he slaves were often prisoners, not their own people
Step-by-step explanation:
from the 16th to the 19th century the Atlantic slave trade took place, this trade involved the transportation of enslaved people from Africa to different places in America, where they were used as the labor force in crops and manufacture. Most enslaved people were captured by other tribes during the wars between different tribes and then sell to slavers, because of this some African leaders have an economic benefit as they captured enemies from other tribes and exchanged for other products from America or Europe while guaranteeing slaves were not part of their tribe, but prisoners from other tribes.
