The Kingdom of Jerusalem, as a Crusader State, was founded at the end of the First Crusade in 1099. Incorporating the County of Tripoli and considered by many to be the jewel of the Crusader Kingdoms, Jerusalem is made up of Franks, native Christians, Jews, Orthodox Christians and Muslims. As a result, a certain degree of religious tolerance exists within Jerusalem, which is now ruled over by the Crusading Franks.
