Fall of Cairo

The Fall of Cairo, also called the Battle of the Pyramids, was the final battle of the Ayyubid Civil War in which the Nizzarid pretenders led by Nizzar himself defeated the last Ayyubid Sultan As-Salih, thus bringing an end to the Ayyubid Sultante which had ruled the regions of Egypt and Levant since its establishment by Saladin.

The defeat of As-Salih is viewed as a formal establishment of the Nizzarid Sultanate, although prior to the battle, Nizzar had already controlled everything from Syria to Alexandria.
