Ubaydallah ibn Muhammad al-Mahdi (Arabic: عبيد الله بن محمد المهدي, romanizedʿUbayd Allāh ibn Muḥammad al-Mahdī)[1] (771–810/11) was an Abbasid prince. He was the son of al-Mahdi, the third caliph of the Abbasid Caliphate, and Raytah, daughter of the first Abbasid caliph Abu al-Abbas al-Saffah.[2]

Life

[edit]

In 761, the future caliph al-Mahdi married Raytah as his first wife after his return from Khurasan.[3] She was the daughter of al-Saffah and his wife Umm Salamah, a Makhzumite.[4] Raytah gave birth to two sons, Ubaydallah and Ali.[3]

During the reign of his half-brother Harun al-Rashid (r. 786–809), Ubaydallah was appointed as governor of Arminiyah and the northwestern provinces in 788/9, succeeding Yazid ibn Mazyad al-Shaybani.[5] He was later appointed to two brief stints as governor of Egypt, in 795 and 796.[6]

In 810 or 811 Ubaydallah died in Baghdad. His nephew al-Amin led the prayers at his funeral.[7]

Siblings

[edit]

Ubaydallah was contemporary and related to several Abbasid caliphs, princes and princesses. He had total ten half-siblings and he had one full brother named Ali ibn Muhammad al-Mahdi.

Notes

[edit]
  1. ^ Le Strange 1922, p. 218 notes that he is sometimes mistakenly referred to as "Abdallah ibn al-Mahdi."
  2. ^ Al-Khatib al-Baghdadi 2011, p. 310; Ibn Hazm 1982, p. 22.
  3. ^ a b Abbott 1946, p. 25.
  4. ^ Abbott 1946, p. 11.
  5. ^ Bosworth 1989, p. 103; Al-Baladhuri 1916, p. 330. Numismatic evidence for this appointment is summarized by Bates 2019, p. 20. Al-Ya'qubi (Gordon et al. 2018, p. 1178) does not note Ubaydallah's governorship, saying instead that Ibn Mazyad was succeeded by Abd al-Kabir ibn Abd al-Hamid. Łewond (Bedrosian 2006, ch. 41), claims that following a conflict between Harun and Ubaydallah the empire was split in two, with Ubaydallah receiving the northern provinces of Atropatene, Armenia, Iberia/Georgia, and Aghuania; this assertion is however disputed by Bonner 1988, pp. 88–89, who notes that the Arabic sources from the period make no reference to any sort of conflict between the two brothers. Ibn Qutaybah n.d., p. 380, refers to Ubaydallah as a governor of the Jazira.
  6. ^ Al-Kindi 1912, pp. 137–38; Ibn Taghribirdi 1930, pp. 93, 101; Khalifah ibn Khayyat 1985, pp. 463–64 (noting only one appointment to Egypt). During his first governorship he was placed in charge of both prayers/security (salah) and finances (kharaj); in his second administration he is mentioned as only being in charge of the salah.
