11. Improved Order of Red Men
Fancy playing dress up? This secret society happens to be another fraternity of mostly Americans whose mode of dress is based on Native American regalia and accessories. Their titles and stages also have Native American names like Sachem, Tribes and Great Chiefs. Originally a bigger group called the Sons of Liberty, they were involved in the Boston Tea Party in 1773, protesting the English tea tax by dumping tea shipments into the sea in a planned attack. The Improved Order of Red Men emerged from some former Sons of Liberty members who went their separate ways and is still active today, claiming to be America’s oldest fraternal organization.
