Caliph ʿAbd al-Malik appointed al-Hajjaj ibn Yusuf to govern Iraq, the empire’s most politically volatile and strategically important province, giving him broad authority to impose order and secure Umayyad control.
Al-Hajjaj’s remit widened beyond Iraq to include key eastern provinces (notably Khurasan and Sistan), effectively making him a viceroy over much of the Umayyad East and its revenues and armies.
Al-Hajjaj initiated conversion of the central fiscal administration (dīwān) in Iraq from Persian to Arabic, part of the wider Umayyad program of administrative standardization and tighter provincial control.
Umayyad forces faced a serious Kharijite challenge in central Iraq led by Shabib ibn Yazid al-Shaybani (beginning in 696); the movement collapsed after Shabib’s death by drowning in 697/698, easing immediate pressure on al-Hajjaj’s administration.
Al-Hajjaj dispatched an elite Iraqi force (the “Peacock Army”) toward Kabulistan/Zabulistan; tensions over al-Hajjaj’s command style and demands contributed to the outbreak of Ibn al-Ashʿath’s major revolt against Umayyad authority.
The revolt (699–701) grew into a broad Iraqi challenge to al-Hajjaj’s governance, threatening Umayyad control by mobilizing garrison-town forces and attracting religious-political opposition to Syrian-backed rule.
Al-Hajjaj’s Syrian-supported forces decisively defeated Ibn al-Ashʿath’s largely Iraqi army at Dayr al-Jamajim, breaking the revolt and enabling tighter Umayyad military supervision of Iraq thereafter.
To strengthen control between Kufa and Basra and to base Syrian troops apart from restive Iraqi garrisons, al-Hajjaj established Wasit as a new administrative and military center.
After the rebellion’s collapse, Ibn al-Ashʿath ultimately died in 704, marking the definitive end of the most dangerous internal challenge faced by al-Hajjaj’s Iraq administration.
In late 704 or early 705, Qutayba ibn Muslim was appointed to govern Khurasan under Umayyad authority, a key eastern command associated with al-Hajjaj’s broader management of the East and its expansion.
From Khurasan, Qutayba launched major operations beginning with the recovery of Lower Tokharistan and Balkh, initiating a sequence of campaigns that extended Umayyad influence deep into Central Asia.
Al-Hajjaj appointed his young relative Muhammad ibn al-Qasim to lead an expedition against Sindh, tying Iraq’s governorship to a major new frontier campaign on the Indian Ocean/Indus route.
Muhammad ibn al-Qasim’s forces defeated the Sindhi ruler Raja Dahir at Aror, a pivotal victory consolidating Umayyad power in Sindh and enabling subsequent occupation and administration.
Al-Hajjaj ibn Yusuf died at Wasit in 714, ending two decades of harsh but consequential rule in Iraq that combined repression of dissent, fiscal-administrative restructuring, and support for eastern expansion.
