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.
Early life and family
Mus'ab was the son of Zubayr ibn al-Awwam, a prominent companion of the Islamic prophet Muhammad. Mus'ab's mother was Rabab bint Unayf, a daughter of a chieftain of the Banu Kalb tribe. During the last years of the Umayyad caliph Mu'awiya I, Mus'ab was part of a group that met together in the mosque of Medina, likely to study religion. The group included, among others, Mus'ab's half-brother Urwa and the later Umayyad caliph, Abd al-Malik ibn Marwan. Mus'ab, like many of his brothers, inherited property from their father in the city's al-Baqi' area and received a home there.Mus'ab had several children from a number of wives and slave women. From one of his wives, a certain Fatima bint Abd Allah, he had his sons Isa al-Kabir, Ukasha and a daughter, Sukayna. He also wed A'isha, a daughter of Talha ibn Ubayd Allah, another prominent companion of Muhammad; she mothered his sons Muhammad and Abd Allah. He also had a daughter, Rabab, from his wife, Sukayna, a daughter of Muhammad's grandson Husayn ibn Ali. From various , he had the sons Hamza, Asim, Umar, Ja'far, Mus'ab, Sa'd, Mundhir, Isa al-Saghir, and a daughter, Sukayna.
Political career and governorship of Iraq
After the death of the Umayyad caliph Yazid in November 683, Mus'ab's older half-brother Abd Allah ibn al-Zubayr was recognized as caliph in most of the Caliphate except for parts of Syria, where Mu'awiya II, and shortly afterwards Marwan ibn al-Hakam, held power for the Umayyads. Mus'ab commanded an expedition against Umayyad controlled Palestine in 684/685. It was repulsed by the Umayyad prince Amr ibn Sa'id al-Ashdaq. Mus'ab was later appointed as governor of Medina. In 685, the Pro-Alid revolutionary Mukhtar al-Thaqafi seized Kufa after expelling its Zubayrid governor. As a result, Zubayrid authority in Iraq was restricted to Basra and its surroundings. At the same time, Kharijite raids in eastern Iraq intensified. To recover Kufa from Mukhtar and defeat the Kharijites, Ibn al-Zubayr appointed Mus'ab governor of Basra in 686. In his inaugural sermon in the mosque he declared: "People of al-Basrah, I have been told that you nickname your commanders. I have named myself 'al-Jazzir'."The Kharijites were a group of ultra-pious secessionists, the most extremists of whom were given to excessive use of arms against those who disagreed with their doctrine. They emerged during the First Fitna from the Kufan pietists in the army of Caliph Ali. They waged war against the governments of Ali and later the Umayyads and Zubayrids, all of whom they viewed as illegitimate rulers. By the time of the Second Fitna, the Iraqi garrison town of Basra had become an epicenter of the Kharijite faction of the Azariqa. Expelled by Zubayrid armies, they fled to the eastern provinces of Fars and Kirman, both dependencies of Basra, frequently raiding the city and its suburbs. Mus'ab sent his most experienced commander, Muhallab ibn Abi Sufra, against them to recover the provinces. Although Muhallab was able to prevent Azariqa raids against Basra, his war lasted years, draining Zubayrid resources. Mus'ab also sent armies against the Najdat Kharijites, who controlled Bahrayn, but the campaigns ended in failure.
In Iraq, Mus'ab built a dyke to prevent the flooding of its marshlands, but appropriated the lands thus acquired for himself.
Defeat of Mukhtar
Previously a Zubayrid ally in the Hejaz, Mukhtar abandoned Ibn al-Zubayr after Yazid's death and returned to his hometown of Kufa. He captured it from the Zubayrids with his Arab and mawali supporters. Soon after, he crushed a rebellion by Arab tribal nobles resentful of the mawali, resulting in an exodus of some ten thousand Kufans to Basra. Persuaded by the refugees to take immediate action against Mukhtar, Mus'ab discontinued his campaign against the Kharijites and marched on Kufa. In a pre-emptive attack, Mukhtar sent his army to Basra, but it was defeated at the Battle of Madhar, just north of Basra. Mus'ab pursued and annihilated the retreating Kufans in the Battle of Harura, a few miles from Kufa. Mukhtar and his remaining supporters took refuge in the palace of Kufa and were besieged by Mus'ab. Four months later, in April 687, Mukhtar was killed in an attempted sortie.Between 6,000 and 8,000 of Mukhtar's supporters surrendered, but Mus'ab gave way to pressure from the vengeful tribal nobles and executed all of them. According to the orientalist Henri Lammens, Mus'ab "executed a considerable number of his supporters". In the account of the historian Abu Mikhnaf, Abd Allah ibn Umar accused Mus'ab of massacring 7,000 Kufans, while the account of al-Waqidi held that among Mukhtar's partisans who surrendered, Mus'ab executed 700 Arabs and all of the Persians, and afterward massacred 6,000 Kufan sympathizers. The executions led to resentment among Kufa's inhabitants, who considered the numerous killings an act of savagery. In the words of Lammens, the slaughter earned Mus'ab "as many enemies as his victims had relatives".
With the defeat of Mukhtar, all of Iraq came under Mus'ab's control. He appointed Muhallab as governor of Mosul and its dependencies to repel potential Umayyad advances on Iraq from Syria. Abd Allah ibn al-Zubayr soon deposed Mus'ab after receiving complaints from the province, and sent his son Hamza as his replacement. The latter proved to be incompetent, and Mus'ab was reinstated in his position.
