Ibrahim ibn Salih

Ibrahim was a son of Salih ibn Ali, a military commander who participated in the conquest of Syria and Egypt during the Abbasid Revolution and later became governor of both regions.[2] As a member of the Banu al-Abbas, he was a first cousin to the first two Abbasid caliphs al-Saffah (r. 750–754) and al-Mansur (r. 754–775), and was additionally a son-in-law to the third caliph al-Mahdi (r. 775–785) by virtue of his marriage to the latter's daughter Abbasa.[3]

In 781 Ibrahim was appointed by al-Mahdi as governor of Egypt, with jurisdiction over both military and financial affairs within the province. During his administration one Dihyah ibn Mus'ab, a descendant of the Umayyad Abd al-Aziz ibn Marwan, launched an anti-tax revolt in Upper Egypt and proclaimed himself as caliph. Ibrahim apparently had a lackadaisical response to the affair, and within a short time much of Upper Egypt had fallen under Dihyah's control. As a result of his failure to stamp out the rebel, an angered al-Mahdi removed him from office in 784, and his assistants were forced to hand over a fine of 300,000 dinars to his successor Musa ibn Mus'ab al-Khath'ami before he was able to return to Baghdad.[4]

During the 780s Ibrahim held several governorships in his father's old powerbase in Syria. As early as 780 he is mentioned as being governor of Palestine,[5] and by the end of al-Mahdi's reign he was in charge of the districts of Damascus and Jordan. Under al-Hadi (r. 785–786) he was retained in those positions and was additionally granted Cyprus and the Jazira. Following the accession of Harun al-Rashid he lost his offices, but in 788 he was restored to the governorship of Damascus.[6]

During his later tenure in Damascus, Ibrahim was forced to deal with a violent conflict that had broken out between the Qays and Yemen tribes of the region. He was eventually able to negotiate a truce between the two factions in 791, after which he led a delegation of Syrian ashraf to meet the caliph in Iraq. Despite his efforts, however, the cessation of hostilities proved to be short-lived, as the rebellion of Abu al-Haydham broke out soon after his departure from the province.[7]

Ibrahim died in 792, shortly after having been appointed governor of Egypt a second time.[8]
