Al-Mu'tamid
Abu’l-ʿAbbās Aḥmad ibn Jaʿfar ibn Muḥammad ibn Hārūn al-Muʿtamid ʿalā’Llāh (Arabic: أبو العباس أحمد بن جعفر; c. 842 – 14 October 892), better known by his regnal name al-Muʿtamid ʿalā 'llāh (المعتمد على الله, 'Dependent on God'), was the caliph of the Abbasid Caliphate from 870 to 892. His reign marks the end of the "Anarchy at Samarra" and the start of the Abbasid restoration, but he was largely a ruler in name only.
