After numerous attempts by the Crusaders of Jerusalem to capture Egypt, Nur al-Din’s forces (led by the general Shirkuh and his nephew, Saladin) seized Cairo in 1169 and forced the Crusader army to evacuate. Upon Shirkuh’s subsequent death, Saladin assumed control and began a campaign of conquests that accelerated after Nur al-Din’s death in 1174. In 1187, Saladin began a major campaign against the Crusader Kingdom of Jerusalem. His troops virtually destroyed the Christian army at the battle of Hattin, taking the city along with a large amount of territory.
