エルサレム王国
The Kingdom of Jerusalem (; ), also known as the Latin Kingdom of Jerusalem or the Frankish Kingdom of Jerusalem, was a Crusader state established in the Southern Levant by Godfrey of Bouillon in 1099 after the First Crusade. The kingdom lasted nearly two hundred years, from 1099 until 1291 when its last remaining possession, Acre, was destroyed by the Mamluks. Its history is divided into two distinct periods.
