Yazid ibn al-Muhallab (672–720) was a provincial governor in the time of the Umayyad dynasty and the progenitor of the Muhallabid family that became important in early Abbasid times. In A.H. 78 (697-698 CE) al-Hajjaj ibn Yusuf, the Caliphate's viceroy of the eastern provinces, appointed Yazid's father al-Muhallab ibn Abi Suffrah as governor of Khurasan. In A.H. 82 (701-702) al-Muhallab's son Mughirah died and al-Muhallab sent Yazid to replace him. Soon afterwards al-Muhallab died and al-Hajjaj appointed Yazid governor of Khorasan. There Yazid confronted external and internal enemies, including some rebels entering his province who were supporters of Abd al-Rahman ibn Muhammad ibn al-Ash'ath. Yazid defeated them. Yazid seized Nizak's fortress and made peace with him.
