Ninth Crusade

The Ninth Crusade was a crusade launched by the crusaders to try to contain Mamlukball advances. Mamlukball had considerably reduced the territory of Kingdom of Jerusalemball and other kingdoms of the region, for example, the Principality of Antiochball, that fell on the Siege of Antioch (1268). After many battles and clashes, Kingdom of Englandball saw that it was wasting time and so a ten-year truce between Mamlukball and the crusaders were signed. Nevertheless, Mamlukball would continue advancing and taking the crusaders territories in the following years, which would result in the fall of the crusader states in the region of the Levant, respectively in the Siege of Tripoli (1289) and in the Siege of Acre (1291).
