The Manx Sword of State is a ceremonial sword that represents the Tynwald on the Isle of Man. It represents the duties of the Sovereign of the Isle of Man, and is used every month in Tynwald, and annually during the Tynwald Day ceremony. There have been three swords used for such functions over the years. One is used for the ceremonies; one is housed in a museum; the other was lost in the 18th century. The Sword of State is popularly said to date to the mid 13th century, however it is not unlike 15th-century ceremonial swords used in England, and recent analysis dates it to the 15th century as well.
