The Three Percenters (aka 3%ers, III%ers, or “Threepers”) are a Patriot movement paramilitary group that pledges armed resistance against attempts to restrict private gun ownership. Adherents and supporters have been associated with threats and acts of violence. Like other Patriot groups, they depict the federal government as tyrannical. Their name refers to the (disputed) percentage of American colonialists who took up arms against the British during the Revolutionary War.

The Three Percenters have a loosely defined membership and a decentralized organizational structure. Seemingly anyone can use the label. There are overlapping Three Percenter organizations, including local, state, and regional leadership structures that coordinate actions and decision-making.

The Three Percenters were co-founded in late 2008 by Mike Vanderboegh, who was active in 1990s Alabama militia groups. Vanderboegh has said, “The Three Percent idea, the movement, the ideal, was designed to be a simple, powerful concept that could not be infiltrated or subjected to agents provocateurs like many organizations that I observed in the constitutional militia movement of the 90s.” Along with the Oath Keepers, the Three Percenters are part of a new wave of Patriot movement groups that are successors to the militia movement of the 1990s and have had a dramatic rebirth since the 2008 election of Barack Obama to the presidency.
