Marwan I

Marwan ibn al-Hakam ibn Abi al-As ibn Umayya, commonly known as Marwan I, was the fourth Umayyad caliph, ruling for less than a year in 684–685. He founded the Marwanid ruling house of the Umayyad dynasty, which replaced the Sufyanid house after its collapse in the Second Muslim Civil War and remained in power until 750.
