Anti-communism is opposition to communism. Organized anti-communism developed in reaction to the rise of communism, especially after the 1917 October Revolution in Russia. It reached global dimensions during the Cold War, when United States and the Soviet Union engaged in an intense rivalry. Anti-communism has been an element of movements of many different positions, including capitalist, liberal, socialist, anarchist, and fascist viewpoints.
Conservative and classical liberal anti-communists argue that centrally planned economies have under-performed free market economies in economic growth and say that communism results in lower liberty. They accuse communists of causing several famines, such as the Russian Famine of 1921 and the much more severe famine in China during the Great Leap Forward.
Some anti-communists refer to both communism and fascism as totalitarianism, seeing similarity between the actions of communist and fascist governments.
Opponents argue that communist parties that have come to power have tended to be rigidly intolerant of political opposition. Communist governments have also been accused of creating a new ruling class (a Nomenklatura), with powers and privileges greater than those previously enjoyed by the upper classes in the non-communist regimes.
