al-amir

Abū ʿAlī al-Manṣūr ibn al-Mustaʿlī (Arabic: أبو علي المنصور بن المستعلي; 31 December 1096 – 7 October 1130), better known by his regnal name al-Āmir bi-Aḥkām Allāh (الآمر بأحكام الله, 'The Ruler Who Executes God's Decrees') was the tenth Fatimid Caliph, and the 20th Imam of Musta'li Isma'ili sect of Shia Islam, from 1101 to his death in 1130. Until 1121, he was a de facto puppet ruler of his uncle and father-in-law, the vizier al-Afdal Shahanshah. When the latter was murdered, possibly with al-Amir's connivance, the caliph appointed al-Ma'mun al-Bata'ihi as vizier, but took an increasing role in government, and after 1125 ruled without a vizier. His reign saw the progressive loss of all Fatimid strongholds in Palestine to the Crusaders, apart from Ascalon. His assassination in 1130, leaving only his infant son al-Tayyib as heir, threw the Fatimid regime into a succession struggle during which it almost collapsed. Fatimid rule was restored with the succession of al-Amir's cousin al-Hafiz li-Din Allah in 1132, which led to the division of Musta'li Isma'ilism into the rival Hafizi and Tayyibi branches.
