ʿAbd Allāh ibn Yazīd ibn Muʿāwiya ibn Abī Sufyān (Arabic: عبدالله بن يزيد بن معاوية بن أبي سفيان), commonly known as al-Uswār, was an Umayyad prince from the Sufyanid line of the dynasty. He was the son of Caliph Yazid I (r. 680–683). After the death of his brother, Caliph Mu'awiya II, in 684, he and his brother, Khalid ibn Yazid, were deemed too young to succeed by the pro-Umayyad tribes of Syria and Umayyad rule was vested in the line of a distant kinsman, Marwan I (r. 684–685). Abd Allah was a famed archer and horseman and commanded part of the army which took over Iraq from anti-Umayyad forces during the Second Muslim Civil War in 691.
