The Jerusalem living history group Regnum-Hierosolymitanum (aka Kingdom of Jerusalem Club) annually reenacts the famous Battle of the Horns of Hattin, in which Salah ad-Din’s forces defeated the crusaders, who ruled the land of Israel. Almost all of the members of Israel’s historical reenactment clubs, as well as visitors from abroad participate in this event. The costumes, weaponry, and tools are made in Medieval traditional methods. The journey and the battle at its end are carried out with as much precision as possible with respect to the historical events and the archaeological findings.
