Marwan I
Yazid tried to end Abdullah's rebellion by invading the Hejaz, and he took Medina after the Battle of al-Harrah followed by the siege of Mecca. His sudden death ended the campaign and threw the Umayyads into disarray, with civil war eventually breaking out. After the Umayyad civil war ended, Abdullah lost Egypt and whatever he had of Syria to Marwan I. This, coupled with the Kharijite rebellions in Iraq, reduced his domain to only the Hejaz.
