Read this: Marwan was succeeded by his son, Abd al-Malik (685–705), who reconsolidated Umayyad control of the caliphate. The early reign of Abd al-Malik was marked by the revolt of Al-Mukhtar, which was based in Kufa. Al-Mukhtar hoped to elevate Muhammad ibn al-Hanafiyyah, another son of Ali, to the caliphate, although Ibn al-Hanafiyyah himself may have had no connection to the revolt. The troops of al-Mukhtar engaged in battles both with the Umayyads in 686, defeating them at the river Khazir near Mosul, and with Ibn al-Zubayr in 687, at which time the revolt of al-Mukhtar was crushed. In 691, Umayyad troops reconquered Iraq, and in 692 the same army captured Mecca. Ibn al-Zubayr was killed in the attack.
