Al-Amir bi-Ahkam Allah

Al-Amir bi-Ahkam Allah, born on December thirty-first, 1096, ascended to the position of the tenth Fatimid caliph at the tender age of five, following the death of his father, al-Musta'li. His early reign, spanning two decades, was characterized by the dominance of his uncle and father-in-law, the vizier al-Afdal Shahanshah, who effectively controlled the Fatimid state while confining Al-Amir to the palace, much like his predecessor.

The turning point in Al-Amir's rule came in December of 1121, when al-Afdal was assassinated, an act officially attributed to agents of the rival Nizari branch of Isma'ilism. However, some medieval narratives suggest that Al-Amir and al-Afdal's chief secretary, al-Ma'mun al-Bata'ihi, may have been involved. Seizing the moment, Al-Amir and al-Bata'ihi swiftly imprisoned al-Afdal's sons and transferred the vast treasures amassed by al-Afdal into the caliphal palace.

With al-Bata'ihi appointed as the new vizier, Al-Amir began to take a more active role in governance, participating in grand public ceremonies. By 1125, he dismissed and imprisoned al-Bata'ihi, marking a significant shift as he ruled without a vizier. Despite the military efforts against the Crusaders in Palestine, Al-Amir's reign witnessed the gradual loss of Fatimid coastal strongholds in the Levant, with Ascalon being one of the few remaining bastions.

In an effort to consolidate power and strengthen alliances, Al-Amir fostered relations with the Musta'li Isma'ili Sulayhid realm of Yemen. In 1122, he issued the al-Hidaya al-Amiriyya, a statement of Musta'li orthodoxy that refuted Nizari claims to legitimacy. Tragically, his reign was cut short when he was assassinated by Nizari agents in 1130, leaving his infant son al-Tayyib as his only heir. This event precipitated a succession crisis that nearly led to the collapse of the Fatimid regime, which was ultimately restored in 1132 with the succession of Al-Amir's cousin, al-Hafiz li-Din Allah, resulting in the division of Musta'li Isma'ilism into the rival Hafizi and Tayyibi branches.
