The Orange Order, also known as the Loyal Orange Institution, is a Protestant fraternal organization that was founded in Ireland in 1795. The group takes its name from Prince William of Orange, who defeated King James II in 1690. The group is known for its celebrations of the Battle of the Boyne, a significant event in Irish history, on July 12th each year. Synonyms for the Orange Order might include the Loyal Orange Lodge, the Order of Orangemen, or simply the Orangemen. The group has been controversial in some circles due to its association with Protestant supremacy and sectarian violence in Northern Ireland.
