Ahmad ibn Isma'il ibn Ali al-Hashimi

Ahmad ibn Isma'il ibn Ali (أحمد بن إسماعيل بن علي الهاشمي) was a minor Abbasid personage and provincial governor who was active in the late eighth and early ninth centuries.

Life
Ahmad was the son of Isma'il and a grandson of Ali ibn Abdallah ibn al-Abbas, and was a first cousin of the first two Abbasid caliphs al-Saffah ((r. 750 – 754)) and al-Mansur ((r. 754 – 775)). During the caliphate of al-Mahdi ((r. 775 – 785)) he was appointed to the governorship of Mosul (781–783/5) and later became al-Mahdi's final governor of Mecca. Under Harun al-Rashid ((r. 786 – 809)) he was again appointed to Mecca and also served as governor of the Yemen (c. 797).

In 803 he was appointed as governor of Egypt. During his tenure in that province, he received an appeal from the Aghlabid governor of Ifriqiya Ibrahim ibn al-Aghlab for help to quell disturbances in the region of Tripoli. He remained in Egypt in two years, before being dismissed and replaced with Abdallah ibn Muhammad ibn Ibrahim al-Zaynabi in 805.
