Ideology of the Communist Party of the Soviet Union

Before the perestroika Soviet era reforms of Gorbachev that promoted Eurocommunism, the formal ideology of the Communist Party of the Soviet Union (CPSU) was Marxism–Leninism, a form of socialism consisting of a centralised command economy with a vanguardist one-party state that aimed to realize the dictatorship of the proletariat. The Soviet Union's ideological commitment to achieving communism included the national communist development of socialism in one country and peaceful coexistence with capitalist countries while engaging in anti-imperialism to defend the international proletariat, combat the predominant prevailing global system of capitalism and promote the goals of Russian Communism. The state ideology of the Soviet Union—and thus Marxism–Leninism—derived and developed from the theories, policies and political praxis of Marx, Engels, Lenin and Stalin.
