Al-Hasan ibn Sahl

Al-Hasan ibn Sahl (died 850/1) was an Abbasid official and governor of Iraq for Caliph al-Ma'mun (reigned 813–833) during the Fourth Fitna.

Hasan's father was an Iranian Zoroastrian convert to Islam. Along with his brother, the future vizier al-Fadl ibn Sahl, Hasan entered the service of the Barmakid al-Fadl ibn Yahya in the reign of Harun al-Rashid (r. 786–809).[1] During the civil war of the Fourth Fitna against Ma'mun's half-brother al-Amin (r. 808–813), he was entrusted with the supervision of the land tax (kharaj) office.[1]

After Ma'mun's troops captured the caliphal capital, Baghdad, Hasan was sent west to assume the governance of Iraq, while Ma'mun and Fadl remained in Marv.[1] In early 815, the Zaydi Alid revolt of Ibn Tabataba and Abu 'l-Saraya al-Sirri broke out at Kufa and spread quickly through southern Iraq. Hasan proved unable to confront it, and the rebels at one point threatened Baghdad itself before the intervention of the capable general Harthama ibn A'yan led to the suppression of the revolt.[1][2] The domination of the Caliphate by Fadl and the Khurasanis around him however aroused great opposition among the old-established Abbasid elites at Baghdad, and Hasan ibn Sahl was forced to abandon the city, where various factional leaders shared power. In July 817, after news reached the city that Ma'mun had chosen an Alid, Ali ibn Musa al-Rida, as his heir-apparent, the city appointed his uncle, Ibrahim ibn al-Mahdi, as Caliph.[1][3]

Following Fadl's murder in 818 and Ma'mun's entry in Baghdad in 819, there were expectations that Hasan would succeed his brother as vizier of the Caliphate, but Hasan, shocked by Fadl's death, preferred to retire from politics and withdraw to his estates around Wasit, where he remained until his death in 850/1.[1] In 825, however, he married his daughter, Buran (807–884), to Ma'mun, and gave her as dowry the palace of Qasr al-Hasani, south of Baghdad, which thereafter became one of the caliphal residences.[1]
