In 1163 Nur ad-Din was asked by Shawar to intervene in Egypt in a dispute between him and Dirgham over the Fatimid vizierate. Nur ad-Din sent Shirkuh, and this was to be the first of three ventures Shirkuh made into Egypt, nominally on Nur ad-Din's behalf. On this first occasion, his nephew Saladin accompanied him as an advisor. Shawar was restored and Dirgham was killed, but after quarrelling with Shirkuh, Shawar allied with Amalric I of Jerusalem, who marched into Egypt in 1164 and besieged Shirkuh at Bilbeis (see Crusader invasion of Egypt). In response Nur ad-Din attacked the Crusader states and almost captured the Principality of Antioch.
