Tahirid Dynasty - Governors of Baghdad

Governors of Baghdad

Besides their hold over Khorasan, the Tahirids also served as the military governors (ashab al-shurta) of Baghdad, beginning with Tahir's appointment to that position in 820. After he left for Khorasan, the governorship of Baghdad was given to a member of a collateral branch of the family, Ishaq ibn Ibrahim, who controlled the city for over twenty-five years. During Ishaq's term as governor, he was responsible for implementing the Mihna (inquisition) in Baghdad. His administration also witnessed the departure of the caliphs from Baghdad, as they made the recently-constructed city of Samarra their new capital. When Ishaq died in 849 he was succeeded first by two of his sons, and then in 851 by Tahir's grandson Muhammad ibn Abdullah.

Abdullah played a major role in the events of the "Anarchy at Samarra" in the 860s, giving refuge to the caliph al-Musta'in and commanding the defense of Baghdad when it was besieged by the forces of the rival caliph al-Mu'tazz in 865. The following year, he forced al-Musta'in to abdicate and recognized al-Mu'tazz as caliph, and in exchange was allowed to retain his control over Baghdad. Violent riots plagued Baghdad during the last years of Abdullah's life, and conditions in the city remained tumultuous after he died and was succeeded by his brothers, first Ubaydullah and then Sulayman. Eventually order was restored in Baghdad, and the Tahirids continued to serve as governors of the city for another two decades. In 891, however, Badr al-Mu'tadidi was put in charge of the security of Baghdad in place of the Tahirids, and the family soon lost their prominence within the caliphate after that.
