مسلمة بن عبد الملك
Abd al-Aziz led his first campaign against the Byzantines in Asia Minor in 709, when he captured a fortress, although his uncle Maslama ibn Abd al-Malik led the main raid of the year afterwards. In 710 he led the main Umayyad attack, although under the auspices of Maslama as commander-in-chief for the Byzantine front, and in 713 he led an attack against the frontier fortress of Gazelon.
