The Kingdom of Jerusalem, also known as the Crusader Kingdom, was a Crusader state that was established in the Levant immediately after the First Crusade. It lasted for almost two hundred years, from the accession of Godfrey of Bouillon in 1099 until the fall of Acre in 1291. Its history is divided into two periods with a brief interruption in its existence, beginning with its collapse after the siege of Jerusalem in 1187 and its restoration after the Third Crusade in 1192.
