The White movement, also known as the Whites, was a loose confederation of anti-communist forces that fought the communist Bolsheviks, also known as the Reds, in the Russian Civil War (1917–1923) and that to a lesser extent continued operating as militarized associations of rebels both outside and within Russian borders in Siberia until roughly World War II (1939–1945). The movement's military arm was the White Army, also known as the White Guard or White Guardsmen.

Anti-communism is political and ideological opposition to communist beliefs, groups, and individuals. Organized anti-communism developed after the 1917 October Revolution in the Russian Empire, and it reached global dimensions during the Cold War, when the United States and the Soviet Union engaged in an intense rivalry. Anti-communism has been an element of many movements and different political positions across the political spectrum, including anarchism, centrism, conservatism, fascism, liberalism, nationalism, social democracy, socialism, leftism, and libertarianism, as well as broad movements resisting communist governance. Anti-communism has also been expressed by several religious groups, and in art and literature.
