In the United States, the patriot movement is a term which is used to describe a conglomeration of non-unified right-wing populist and neo-fascist nationalist political movements, most notably far-right armed militias, sovereign citizens, and tax protesters. Ideologies held by patriot movement groups often focus on anti-government conspiracy theories, with the Anti-Defamation League (ADL) describing a common belief that "government has been infiltrated and subverted" and is no longer legitimate. The movement first emerged in 1994 in response to what members saw as "violent government repression" of dissenting groups, along with increased gun control and the Clinton government.
Several groups within the patriot movement have committed or endorsed violence, with U.S. law enforcement agencies labeling some groups "dangerous, delusional and sometimes violent." The ADL and The American Scientific Affiliation has noted that groups often have connections to white supremacy, however, their connections to it have shrunk over time due to their recent inclusion of non-white members. Major events in America which alarm or inspire the patriot movement include the 1992 Ruby Ridge siege, the 1993 Waco siege and the 1995 Oklahoma City Bombing. The Southern Poverty Law Center (SPLC) found that the economic decline and nomination of Barack Obama in 2008 caused the movement to "come roaring back", after declining from 800 groups in 1996 to less than 150 groups in 2000.
Historians of the patriot movement identify its origins in the 1980s American farm crisis. As various policies combined to drive farmers deeply into debt, groups on the margins of American politics engaged rural communities with a range of conspiracy theory literature that drew on existing traditions of antisemitism, nativism and paleoconservatism. The Posse Comitatus, the Liberty Lobby and Lyndon LaRouche were prominent in these campaigns which informed and shaped the ideology of the movement that emerged. In the early 1990s, the patriot movement saw a surge of growth spurred by the confrontations at Ruby Ridge and Waco.
