The Crusader states were feudal polities created by the Latin Catholic leaders of the First Crusade through conquest and political subterfuge. Four states were established: the county of Edessa (1097–1150); the principality of Antioch (1098–1287), the county of Tripoli (1102–1289), and the kingdom of Jerusalem (1099–1291).
