Mohammedans started the African slave trade.
Virtually all African slaves were peoples captured by Moslems and sold into slavery.

"There has been a recrudescence of jihad slavery since 1983 in the Sudan.[23][24]
Slavery in the Sudan predates Islam, but continued under Islamic rulers and has never completely died out in Sudan. In the Sudan, Christian and animist captives in the civil war are often enslaved, and female prisoners are often used sexually, with their Muslim captors claiming that Islamic law grants them permission.[25]"
