Like the Orange Order it is a Protestant fraternal organisation dedicated to the principles of the Protestant Reformation. It takes its name in memory of King William of Orange of the house of Orange who fought at the Battle of the Boyne, brought about the Glorious Revolution and the Bill of Rights giving the Westminster parliament ultimate power of the country rather than the Monarch. The Independent Order is small compared to the main organisation with about 350–400 members.It is largely based around north County Antrim in Northern Ireland but has lodges around the world, including England, Scotland and Australia. Its annual main Twelfth of July demonstration is held in a north Antrim town or village.
