Abu Muslim
Abu Muslim and the Abbasid Revolution

He took Merv in December 747 (or January 748), defeating the Umayyad governor Nasr ibn Sayyar, as well as Shayban al-Khariji, a Kharijite aspirant to the caliphate. He became the de facto governor of Khurasan, and gained fame as a general in the late 740s in defeating the rebellion of Bihafarid, the leader of a syncretic Persian sect that was Mazdaist. Abu Muslim received support in suppressing the rebellion both from purist Muslims and Zoroastrians.
