Shawar

Shawar ibn Mujir al-Sa'di was an Egyptian military leader and politician. He was the de facto ruler of Fatimid Egypt, as its vizier, from December 1162 until his assassination in 1169 by the general Shirkuh, the uncle of the future Ayyubid leader Saladin, with whom he was engaged in a three-way power struggle against the Crusader Amalric I of Jerusalem. Shawar was notorious for continually switching alliances, allying first with one side, and then the other, and even ordering the burning of his own capital city, Fustat, just so that the enemy could not have it.
