Justin Marozzi is a historian and author of Captives and Companions, a sweeping history of slavery in the Islamic world. Marozzi and Coleman discuss the origins and scale of the Islamic slave trade, the role of religion and law in shaping it, and why this subject has long been a historical blind spot in the West. They also discuss the trans-Saharan slave trade, the Barbary corsairs, and why forms of slavery still exist in places like Mauritania and Mali.
