Authoritarian conservatism is a political ideology that seeks to uphold order, tradition, and hierarchy, often with forcible suppression of radical and revolutionary enemies such as communists, Nazis, and anarchists. Authoritarian conservative movements and regimes have included Chiangism in the Republic of China, Metaxism in Greece, Francoism in Spain, Regency of Miklós Horthy in Hungary, and Vichyism in the French State.
The rise of authoritarian conservatism coincided with the rise of fascism. In some cases, the authoritarian conservatism clashed with fascism, like in Austria and Portugal, while in other cases, like in Francoist Spain, Vichy France, and Fascist Italy, it cooperated with fascism. Although both ideologies espoused nationalism and anti-communism, the traditionalist nature of authoritarian conservatism made it distinct from the revolutionary, palingenetic, and populist nature of fascism. While fascism espoused vitalism, irrationalism, or secular neo-idealism, the authoritarian conservatism based its views on the traditional religion.
