Al-Musta'li

Ahmad al- Musta ʿ li (Arabic أحمد المستعلي, DMG Aḥmad al - Musta ʿ lī, † 1101) was from 1094 the ninth Fatimid Caliph.

Ahmad al - Mustali was enforced by the Regent al - Afdal Shahanshah (r. 1094-1121 ) as successor to al - Mustansir († 1094 ). As with his brother Nizar entitled to inherit the throne was passed over, there were power struggles within the Fatimids. It failed at a riot Nizars ( he was killed in prison), but resulted in the breaking of the rules of succession to split the Ismailis. Thus arose in Persia and Syria, the still existing church of Nizariten that is passed into history under the name of the Assassins.

Incidentally, al - Mustali was under the control of al - Afdal, who led the government of the empire. After 1099 originated in Palestine as a result of the First Crusade, the Kingdom of Jerusalem and the counties of Tripoli and Antioch, which limited the capacity of the Fatimids in Syria continues. Successor of al - Mustali was his son al -Amir (r. 1101-1130 ).
