Question

List three factors that caused africa to become a growing source of slaves for the slave trade

Answer 1

1) The other developing countries like the Americas, were growing and they traded items like guns to Africa for slaves, eventually, this became a competition
2)Another factor is that the Africans themselves have use slaves themselves in a fair way and it just sparked them to use them
3) Becuase of this demand, Africa was eventually built on the slaves

All this happened because of trading

Answer 2

Here are three factors that caused slavery to grow in Africa:

Slavery had existed in Africa for hundreds of years, especially in the Middle East. Europeans expanded this already existing slave trade.  

Tribal and other wars were a major cause of the growth of slavery in Africa. After these wars, the soldiers from the losing side were taken prisoner and sold into slavery.

Europeans needed cheap labor to work their land in the Americas.
