I want to know the answer to the following question:
Where did the Spanish and Portugese enslave most of their black people from?
All the background I'm provided with is that "As Spain and Portugal sourced most of their slaves from South-West Africa (the Portuguese through ports in modern-day Angola; the Spanish purchased most of their African slaves from Portuguese traders, and from Arabs whose slave trading was centred in Zanzibar).". Is that enough to answer the question?
