Al-Musta'li

Timeline

1. 1094–1100Cairo · CairoAfter his father al-Mustansir died in 1094, vizier al-Afdal deposed his elder brother al-Nasir and installed al-Musta'li on the throne, triggering the Ismaili 'Nizari' schism. During the First Crusade the Fatimids first took Jerusalem only to lose it to the crusaders; under al-Musta'li's nominal rule Egypt itself remained stable, but Syrian and Palestinian territories were largely lost.
2. 1101Cairo · CairoIn 1101, al-Musta'li's final year, vizier al-Afdal continued to direct diplomacy and military affairs against the crusaders and Muslim powers in Damascus. Al-Musta'li died in Cairo on December 12, 1101, at only twenty-seven years of age; by his decree his young son al-Amir succeeded him, and the Fatimids entered an era of child rulers and regencies, accelerating the dynasty's decline.
