Like his father al-Musta‘lī (1094–1101), al-Āmir was controlled by the regent al-Afdal Shahanshah (1094–1121) and had little influence in political matters. However, after the overthrow of al-Afdal in 1121 he managed to gain control of government. His reign was marred by the loss of Tyre to the Crusaders, as well as by the continuation of the schism between the Nizari and the Mustaali. This conflict climaxed in the assassination of al-Amir on 1130 AD or 524 AH.
His death led to further power struggles, through which Al-Hafiz, a cousin of al-Amir, eventually came to power, while the Taiyabiah claimed that Taiyab abi al-Qasim, the four-year-old son of al-Amir was the rightful successor as Imam.
