Life

Mansur was the son of al-Mahdi and his mother was al-Bahtariyah, the noble-born daughter of the Persian rebel,^[1] Masmughan of Damavand,^[2] against whom Mahdi was first sent to Khurasan.^[1] Her mother was Bakand, the daughter of Isbahbadh, Farrukhan the Little.^[3] She had a sister named Smyr.^[2] She bore al-Mahdi a son named for his grandfather, Mansur, and two daughters, Sulaimah and Aliyah.^[1]

His father, nominated his two elder sons; Musa al-Hadi and Harun al-Rashid as heirs. Mansur maintains good relations with all his siblings.

Mansur was appointed as governor of Syria in 809. He remained in office until al-Amin reappointed Sulayman to govern Syria around 809–810 in response to unrest in Damascus emanating from the theft of a prized crystal pitcher from the Umayyad Mosque by the incumbent governor, Sulayman's nephew Mansur. The outrage of the Damascenes prompted them to refuse prayer under Abbasid leadership.^[4]

After his dismissal from the office, Mansur returned to Baghdad in 810.
