Yazid ibn Abd al-Malik ibn Marwan, commonly known as Yazid II, was the ninth Umayyad caliph, ruling from 720 until his death in 724. Although he lacked administrative or military experience, he derived prestige from his lineage, being a descendant of both ruling branches of the Umayyad dynasty, the Sufyanids who founded the Umayyad Caliphate in 661 and the Marwanids who succeeded them in 684. He was designated by his half-brother, Caliph Sulayman ibn Abd al-Malik, as second-in-line to the succession after their cousin Umar, as a compromise with the sons of Abd al-Malik.
