عبد الله بن الزبير
He virtually inherited the governorships from his father Ziyad ibn Abihi after the latter's death in 673. During Ubayd Allah's governorship, he suppressed Kharijite and Alid revolts. In the ensuing Battle of Karbala in 680, Husayn and his small retinue were slain by Ubayd Allah's troops, shocking many in the Muslim community. Ubayd Allah was ultimately evicted from Iraq by the Arab tribal nobility amid the revolt of Abd Allah ibn al-Zubayr.
