The Orange Order was formed to defend the interests of Protestant Irishmen against Catholics, particularly in Ulster. It was named in honour of William of Orange who came to the British throne in the Glorious Revolution in 1688 and whose armies defeated the Catholic King James II at the Battle of the Boyne in 1690.</ p>
