Yazid ibn Hatim al-Muhallabi (Arabic: يزيد بن حاتم المهلبي) (died March 13, 787) was a member of the Muhallabid family who served as the governor of Adharbayjan, Egypt (762–769) and Ifriqiya (771–787) for the Abbasid Caliphate.
[3] In 755 he was one of the commanders who attempted to put down the Kharijite rebel Mulabbid ibn Harmalah al-Shaybani in the region of Mosul, but he was defeated and forced to withdraw.
As a trusted aide of the caliph, his appointment was intended to secure Abbasid control of Egypt, especially against Alid agitation, which his predecessor, Humayd ibn Qahtaba had ignored.
[8] Following the death of the governor of Ifriqiya, 'Umar ibn Hafs al-Muhallabi, at the hands of Kharijite rebels in 771, al-Mansur appointed Yazid to that position and dispatched him to the province with a massive army.
After arriving in Tripoli, Yazid advanced against the Ibadis in early 772 and engaged them in a major battle, killing their leader Abu Hatim Yaqub ibn Labib al-Khariji and a large number of the rebels.
