Events of the reign

The Revolt of Nizar ibn al-Mustansir at Alexandria and Its Suppression in 495

In al-Musta'li's days his brother Nizar — namesake of the Nizari da'wa of Alamut — fled to Alexandria, whose people swore to him with the backing of its qadi Ibn Ammar and its governor Iftakin; al-Afdal b. Badr al-Jamali besieged them, beat Iftakin's sortie, then prevailed and carried both men back to Cairo, where Iftakin was slaughtered and Nizar was walled up and perished.
