Far-right politics encompasses a range of ideologies that are marked by ultraconservatism, authoritarianism, ultranationalism, radical anti-communism, ethnonationalism, and nativism. This political spectrum situates itself on the far end of the right, distinguished from more mainstream right-wing ideologies by its opposition to liberal democratic norms and emphasis on exclusivist views. Far-right ideologies have historically included reactionary conservatism, fascism, and Nazism, while contemporary manifestations also incorporate neo-fascism, neo-Nazism, supremacism, and various other movements characterized by chauvinism, xenophobia, and theocratic or reactionary beliefs.
Key to the far-right worldview is the notion of societal purity, often invoking ideas of a homogeneous "national" or "ethnic" community. This view generally promotes organicism, which perceives society as a unified, natural entity under threat from diversity or modern pluralism. Far-right movements frequently target perceived threats to their idealized community, whether ethnic, religious, or cultural, leading to anti-immigrant sentiments, welfare chauvinism, and, in extreme cases, political violence or oppression. According to political theorists, the far right appeals to those who believe in maintaining strict cultural and ethnic divisions and a return to traditional social hierarchies and values.
