The Improved Order of Red Men is a fraternal organization established in North America in 1834. It claims direct descent from the colonial era Sons of Liberty. Their rituals and regalia are modeled after those assumed by men of the era to be used by Native Americans. Despite the name, the order was formed solely by, and for, white men. This whites-only rule was part of their bylaws until 1974, when the all-white clause was eliminated. Their current position is that they are now open to people of all ethnic backgrounds. In 1935 the organization claimed a membership of about half a million, but it has now declined to a little more than 15,000.

The Sons of Liberty was a loosely organized, clandestine, sometimes violent, political organization active in the Thirteen American Colonies founded to advance the rights of the colonists and to fight taxation by the British government. It played a major role in most colonies in battling the Stamp Act in 1765 and throughout the entire period of the American Revolution. Historian David C. Rapoport called the activities of the Sons of Liberty "mob terror."
