 For the next seven centuries, up to today, a veritable multitude of European monarchs have used the title of King of Jerusalem.The Latin population of the kingdom was always small; although a steady stream of settlers and new crusaders continually arrived, most of the original crusaders who fought in the First Crusade simply went home.According to William of Tyre, "barely three hundred knights and two thousand foot soldiers could be found" in the kingdom in 1100 during Godfrey's siege of Arsuf.
