[2][3] In the next year, the Byzantine Armenian provinces east of the Euphrates, recently conquered by Muhammad ibn Marwan, rose in a revolt that spread out over much of Armenia.
In 703, Abdallah conquered Mopsuestia (al-Massisa) in Cilicia, which he refortified as the Caliphate's first major stronghold in the area, and then proceeded to subdue the Armenian revolt along with his uncle Muhammad.
[3][6] In late 704 he was recalled from Armenia to serve as governor of Egypt, succeeding his long-serving uncle Abd al-Aziz ibn Marwan.
His tenure was marred by the first famine under Islamic rule and by accusations of corruption and embezzlement of public funds.
