Description acceptable. Due to the outcome of this event, the word dawla shifted its meaning from “turn” to “dynasty.” Julius Wellhausen ascribed the causes of this event to Persian resentment for their disprivileged status under the “Arab Kingdom.” The Akhbār al-Dawla reveals this event’s original goal was to empower the Hashemites instead of a branch family. Support for this movement came from Khurāsān, where new converts called mawālī were alienated by harsh kharāj and jizya taxes. Merv was captured during this uprising by an army under the Black Standard. Abū Muslim’s victory over Marwān II at the Battle of Zab during this uprising enabled a dynasty to establish itself in newly-founded Baghdad. For 10 points, name this uprising that overthrew the Umayyad Caliphate. ■END■
