يزيد بن المهلب
Shortly before or immediately after Yazid's accession, the veteran commander and disgraced governor of Iraq and the vast eastern province of Khurasan, Yazid ibn al-Muhallab, escaped from the fortress of Aleppo where Umar II had him imprisoned. During Sulayman's reign, Ibn al-Muhallab, an enemy of al-Hajjaj, had been responsible for the torture and deaths of members of al-Hajjaj's family, Yazid's in-laws, and feared retaliatory maltreatment when Yazid's accession became apparent. Yazid had long held suspicions, nurtured by al-Hajjaj, of Ibn al-Muhallab's and the Muhallabid family's influence and ambitions in Iraq and the eastern Caliphate.
