Slavery in the Umayyad Caliphate
Slavery in the Umayyad Caliphate refers to the chattel slavery taking place in the Umayyad Caliphate (661–750), which comprised the majority of the Middle East with a center in the capital of Damascus in Syria. The slave trade in the Umayyad Caliphate was massive and expanded in parallel with the Umayyad imperial conquests, when non-Muslim war captives as well as civilians were enslaved, and humans were demanded by tribute and taxation from subjugated people.
