Abu Ahmad Ubaydallah ibn Abdallah ibn Tahir (Arabic: أبو أحمد عبيد الله بن عبد الله بن طاهر, c. 838 – May 913)[1] was a ninth century Tahirid official and military officer. He was the last major Tahirid to hold high office,[2] having served as the governor of Baghdad at various points between 867 and 891.[3]


Ubaydallah was the son of Abdallah ibn Tahir, the governor of Khurasan from 828 to 845. During the civil war of 865–866 he was present in Baghdad, and throughout the siege of the city he served in a military capacity under his brother Muhammad ibn Abdallah ibn Tahir, who as governor commanded the overall defense against the besiegers. At the end of the war, he was responsible for transferring the signet, cloak and scepter of the defeated caliph al-Musta'in (r. 862–866) to the victor al-Mu'tazz (r. 866–869).[4]

Upon Muhammad's death in November 867, Ubaydallah assumed the governorship of Baghdad as his brother's designated successor, and he quickly received formal confirmation from al-Mu'tazz. During his first term as governor, he was responsible for hunting down the sons of the Turkish officer Bugha al-Sharabi following the latter's execution in 868. Before long, however, he was beset by fiscal problems which made it difficult for him to pay the salaries of the troops in the city, and was eventually compelled to surrender the governorship to his brother Sulayman ibn Abdallah ibn Tahir in 869.[5]

Following Sulayman's death in late 879, Ubaydallah was again appointed as head of security (shurtah) in Baghdad, this time as deputy to the Saffarid Amr ibn al-Layth, who had been granted that position by the central government.[6] He probably held the governorship until 885, when a reversal in caliphal policy toward the Saffarids resulted in 'Amr being formally dismissed from office.[7] In August 889 he was restored to the shurtah following a rapprochement between the central government and 'Amr, but in 891 the Abbasid prince Abu al-Abbas ibn al-Muwaffaq (the future caliph al-Mu'tadid, r. 892–902) appointed his own page Badr al-Mu'tadidi to that position instead.[8]

During the reign of al-Mu'tadid Ubaydallah fell into a period of hardship, and in his last years he relied on financial assistance from prominent individuals such as al-Muktafi, Ibn al-Mu'tazz, and Ahmad and Ali of the Banu'l-Furat.[9] He died in Baghdad in May 913.[1]


Aside from his political career, 'Ubdaydallah was renowned for his extensive cultural patronage and expertise, leading the historian Clifford Edmund Bosworth to call him "the most celebrated of his family in the literary and artistic fields."[10] He was considered to be proficient in adab literature, poetry, grammar, history, geometry, and music, and his skills in these fields were praised by authors such as Abu al-Faraj al-Isfahani and al-Shabushti. As a musician he was known to have composed several melodies for prominent signers of the time, although he was too proud to openly take cr for his pieces and attributed them to a singing girl that he owned instead. He also enjoyed a longstanding relationship with the poet Ibn al-Rumi, and was one of the largest dedicatees of the latter's poetry.[11]

Ubaydallah was the author of several works, although they are now believed to be lost. Among his writings were a book about poems and poets (Kitab al-ishara fi akhbar al-shi'r), a treatise on government (Risala fi al-siyasa al-mulukiyya), a collection of letters sent to him by the Abbasid prince and poet Ibn al-Mu'tazz, a book on melody and the background behind the composition of well-known songs (Kitab al-adab al-rafi'a), and a work on rhetoric (Kitab al-bara'a wa al-fasaha). His poetry was also organized into a collection (diwan), and many of his verses were transmitted by later writers.[12]

  3. ^ The dates of his governorships used here are derived from Bosworth 1996, p. 168, supplemented by Al-Tabari 1985–2007, v. 35: pp-149-50; v. 36: pp. 13-15; v. 37: pp. 1, 2, 147, 160, 168. Hamzah al-Isfahani 1844, pp. 181–184, however, provides contradictory information, mentioning a first governorship of unspecified date, a second governorship lasting from 873 (when Muhammad ibn Tahir was captured by Ya'qub ibn al-Layth al-Saffar) to 876 (when Muhammad was freed following the Battle of Dayr al-'Aqul), and a third governorship commencing in 879. Hamzah al-Isfahani's dates are at times used by modern authors, e.g. Guest 1944, p. 14, and Bosworth 1982, p. 72 acknowledges the chronological issues, commenting that Ubaydallah was "three or possibly four times governor of Baghdad."

  5. ^ Al-Tabari 1985–2007, v. 36: pp. 13-15; Al-Ya'qubi 1883, p. 613. Before resigning the governorship, he emptied the treasuries and collected taxes on immature crops, leaving Sulayman with a major shortage of funds. Ubaydallah is subsequently mentioned in the year 874 by al-Tabari, v. 36: p. 163, as being ordered by the central government to read a statement to pilgrims from several provinces that were present in Baghdad, declaring that Yaqub ibn al-Layth was not the legitimate governor of Khurasan. This account, which suggests that Ubaydallah was in a position of authority in Baghdad, might accord with Hamzah al-Isfahani 1844, p. 182, who claims that he was actually governor of the city at the time.
  6. ^ Al-Tabari 1985–2007, v. 37: pp. 1, 2.
  7. ^ Al-Tabari 1985–2007, v. 37: p. 147; Muhammad ibn Tahir was invested with the governorship of Khurasan on this occasion, but al-Tabari is silent on whether or not he received the governorship of Baghdad as well. In that same year, however, al-Husayn ibn Isma'il is mentioned as being Muhammad's sahib al-shurtah in Baghdad; v. 37: p. 148. Ubaydallah was likely still governor in 882-883, when his son was acting as his deputy in Baghdad; v. 37: p. 81, and Guest 1944, pp. 14, 79.
  8. ^ Al-Tabari 1985–2007, v. 37: pp. 160-61, 168. Badr's appointment represents the latest date that Ubaydallah could have lost his office. Al-Tabari mentions that in February 890, Ubaydallah's patron 'Amr suffered another reversal in his relations with the central government, and that "orders were issued to remove the poles, flags and shields" bearing his name from the headquarters of the shurtah. He does not specify if Ubaydallah was dismissed at this point.
