Which of the following is a well-known African departure point for enslaved Africans during the Transatlantic Slave Trade?

Zanzibar is a significant site in the context of the Transatlantic Slave Trade, primarily because it was a key hub for the slave trade in East Africa. It played an integral role in the trade networks that transported enslaved Africans to various parts of the world, particularly to the Middle East and the Americas.

Historically, Zanzibar served as a center for the capturing and processing of enslaved people, facilitating their transfer to larger markets. The island's strategic location made it a focal point for traders involved in the slave economy during the 18th and 19th centuries. In contrast, although Timbuktu was important for trade and culture, it was not primarily known as a departure point for enslaved Africans related to the Transatlantic Slave Trade. Alexandria and Cape Town similarly had their own roles in trade but did not serve as prominent departure points for enslaved Africans in the same way that Zanzibar did.
