Mus'ab ibn al-Zubayr

Mu'sab ibn al-Zubayr ibn al-Awwam al-Asadi was the governor of Basra in 686–691 for his brother, the Mecca-based Caliph Abd Allah ibn al-Zubayr, during the Second Fitna. Mus'ab was a son of Zubayr ibn al-Awwam, a prominent companion of the Islamic prophet Muhammad. Before becoming governor, he led an unsuccessful campaign against Umayyad-held Palestine. He defeated and killed the Pro-Alid revolutionary Mukhtar al-Thaqafi after a series of battles in 687, gaining control over all of Iraq. Complaints from the Iraqis caused his removal from office by his brother, but he was restored shortly after. He was killed by Umayyad forces led by Caliph Abd al-Malik in the Battle of Maskin four years later.
