Which areas were major slave trade locations in Central Africa?

The correct answer identifies Zanzibar, Sudan, and Guinea as major slave trade locations in Central Africa. Historically, these areas were integral to the transatlantic and trans-Saharan slave trades. Zanzibar, an island off the east coast of Africa, served as a significant trading post where slaves were transported to various regions, especially to the Arabian Peninsula and India. The market for slaves was prominent in Sudan, where the trade routes intersected, facilitating the movement of captives from the interior of Africa to the northern parts and other international markets. Guinea also played a vital role as a point of departure for many enslaved Africans sent across the Atlantic.

This understanding of the historical context surrounding these locations reflects their importance during periods of intense trade and interaction involving human trafficking, making them key geographic points in the study of the slave trade in Africa.
