African slave trade

In evaluating the African slave trade, there was another "Middle Passage" often neglected by most scholars—the Arab slave trade. It is often forgotten that the Arab slave trade in East Africa and the slave trade from North Africa into Inner West Africa was protracted and ruthless. Sometimes the Arabs from the north who were Moslem enslaved Africans in the south who were also Moslems, thereby violating one of the most basic customs of their faith—that no Moslem should enslave another Moslem.
