Al-Walid I, Umayyad caliph (born 668)

Al-Walid ibn Abd al-Malik ibn Marwan, commonly known as al-Walid I, was the sixth Umayyad caliph, ruling from October 705 until his death in 715. He was the eldest son of his predecessor, Caliph Abd al-Malik. As a prince, he led annual raids against the Byzantines from 695 to 698 and built or restored fortifications along the Syrian Desert route to Mecca. He became heir apparent in c. 705, after the death of the designated successor, Abd al-Malik's brother Abd al-Aziz ibn Marwan.

The Umayyad Caliphate or Umayyad Empire was the second caliphate established after the death of the Islamic prophet Muhammad and was ruled by the Umayyad dynasty. Uthman ibn Affan, the third of the Rashidun caliphs, was also a member of the clan. The family established dynastic, hereditary rule with Mu'awiya I, the 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.
