Ubayd Allah ibn Ziyad
After Muawiyah's death in April 680, Yazid ordered the governor of Medina, where all his opponents were based, to obtain their obedience. Of these, Husayn ibn Ali and Abd Allah ibn al-Zubayr evaded the governor and escaped to Mecca. There Husayn received letters from the Iraqi garrison town of Kufa with the invitation to revolt against Yazid and regain his rightful place as the leader of the Muslim community which his father, Ali (), had previously held. Husayn sent his cousin Muslim ibn Aqil to prepare the ground for his arrival. Ibn Aqil sent back a favorable report, urging Husayn to depart for Kufa. Shortly afterwards, Ibn Aqil was apprehended and executed by the Umayyad governor Ubayd Allah ibn Ziyad and his supporters suppressed. Unaware of the situation, Husayn left for Kufa, but was intercepted and killed just outside of the town. His expected support never arrived.
