Following the principles of feudalism, the foundation for these polities was laid by the First Crusade, which was proclaimed by the Latin Church in 1095 in order to reclaim the Holy Land after it was lost to the 7th-century Muslim conquest. From north to south, they were: the County of Edessa (10981150), the Principality of Antioch (10981268), the County of Tripoli (11021289), and the Kingdom of Jerusalem (10991291).
