The Umayyad Caliphate (661–750 CE) was the second caliphate established after the death of the Islamic prophet Muhammad. The caliphate was ruled by the Umayyad dynasty, also known as the Umayyads (, al-ʾUmawīyūn, or , Banū ʾUmayya, "Sons of Umayya"). Uthman ibn Affan (r. 644–656), the third of the Rashidun caliphs, was also a member of the clan. The family established dynastic, hereditary rule with Muawiya ibn Abi Sufyan, long-time governor of Greater Syria, who became caliph after the end of the First Fitna in 661. After Mu'awiya's death in 680, conflicts over the succession resulted in the Second Fitna, and power eventually fell to Marwan I, from another branch of the clan. Syria remained the Umayyads' main power base thereafter, with Damascus as their capital.
