Charles d’Anjou, who had conquered Sicily in 1266, allied himself with Prince Edward of England, who had arrived in Tunis in 1270. When Charles d’Anjou called off the attack on Tunis, Edward went on to Acre, the last Crusader outpost in Syria, in an attempt to restore the “Kingdom of Jerusalem”. His time spent there (1271-1272) is called the Ninth Crusade. This crusade is considered to be the last major Mediœval Crusade to the Holy Land. The Ninth Crusade failed largely because the crusading spirit was nearly extinct in Europe, and because of the growing power of the mamluks in Egypt. It also foreshadowed the imminent collapse of the last remaining Crusader strongholds along the Mediterranean coast.
