The African slave trade was started by....er.....Africans.
And flourished for a 1000 years under Islam.
The sale of African slaves can be traced back to antiquity. It became popular in the seventh century when Islam was gaining strength in North Africa. This was seven centuries before Europeans explored the continent and ten centuries before West Africans were sold across the Atlantic to America.

Back then, Arab Muslims in North and East Africa sold captured Africans to the Middle East. There, they worked as field workers, teachers or harem guards, which is why the castration of male slaves was common practice. Muslims, on the other hand, including African Muslims, were not allowed to be enslaved, according to Islamic legal views.
"Initially, the Arab Muslims in Eastern and Central Europe took white slaves to sell them to Arabia," Senegalese author Tidiane N'Diaye told DW in an interview. "But the growing military power of Europe put an end to Islamic expansion and now that there was a shortage of slaves, Arab Muslims were looking massively to black Africa."
Roots of slavery in Africa
According to N'Diaye, slavery has existed in practically all civilizations. This was also the case in Africa before settlers came.
In central East Africa, ethnic groups such as the Yao, Makua and Marava were fighting against each other and entire peoples within the continent traded with people they had captured through wars. "Thus Arab Muslims encountered already existing structures, which facilitated the purchase of slaves for their purposes."
