Ubayd Allah's father prepared him to succeed him as governor, and indeed, after Ziyad's death in 672/673, Ubayd Allah became governor of Khurasan. A year or two later, he was also appointed to the governorship of
Basra. According to historian
Hugh N. Kennedy, Ubayd Allah was "more hasty and given to the use of force than his father, but a man whose devotion to the Umayyad cause could not have been doubted". In 674 he crossed the
Amu Darya and defeated the forces of the ruler of
Bukhara in the first known invasion of the city by Muslim Arabs. After he was appointed governor of Basra soon afterwards, he also took several thousand Bukharan captives with him as slaves. Out of those slaves the Bukhariya military unit was formed. From at least 674 and 675, Ubayd Allah had coins struck in his name in Khurasan and Basra, respectively. They were based on
Sasanian coinage and written in
Pahlavi script. The mints were located in Basra, Darabjird,
Maysan,
Narmashir, Jayy and, to a lesser extent,
Kufa. The latter was attached to Ubayd Allah's governorship in 679/680, giving him full control of Iraq.
Suppression of the pro-Alid groups Mu'awiya died in 680 and was succeeded by his son
Yazid I. Mu'awiya's designation of his son was an unprecedented act and shocked many in the Muslim community, particularly the Arab nobility of Kufa. They long sympathized with Caliph
Ali, Mu'awiya's former rival, and Ali's family. One of Ali's sons,
Husayn dispatched his cousin
Muslim ibn Aqil to Kufa to set the stage for Husayn's accession to the caliphate. Ibn Aqil garnered significant support and was hosted by a prominent pro-
Alid nobleman. Ubayd Allah became aware of Ibn Aqil's activities, prompting the latter to launch a premature assault against the governor. Ubayd Allah was holed up in his palace, but thirty men from his
shurta (security forces) fended off Ibn Aqil's partisans, while he persuaded many Kufan noblemen to back him against Ibn Aqil, who was abandoned by his supporters and slain on 10 September 680. Husayn had already been en route to Kufa from
Medina when he received news of Ibn Aqil's execution. Ubayd Allah was prepared for Husayn's arrival and sent troops to intercept him. They prevented Husayn and his small retinue from reaching the watered areas of the province. The two sides negotiated for weeks, but Ubayd Allah refused Husayn entry into Kufa or return to Arabia while Husayn refused to recognize Yazid's caliphate. In the end, a short
battle was fought at
Karbala on 10 October 680, in which Husayn and nearly all of his partisans were slain. Husayn had never received the expected backing of his Kufan sympathizers, but the latter's resentment festered as a result of his death. The slaying of Husayn, a grandson of the Islamic prophet
Muhammad, perturbed many Muslims. ==Role in Umayyad succession of 684==
