State ideology of the Union of Soviet Socialist Republics

The ideology of the Communist Party of the Soviet Union was a state sponsored Marxist-Leninist ideology based around a heavy central planning, a centralized vanguard party rule, and the attempt to develop socialism at a national level, co-existing with capitalist nations.

Marxism–Leninism was the cornerstone of Soviet ideology. It explained and legitimised the CPSU's right to rule, while explaining its role as a vanguard party. For instance, the ideology explained that the CPSU's policies, even if they were unpopular, were correct because the party was enlightened. It was represented to be the only truth in Soviet society, and with it rejecting the notion of multiple truths. In short, it was used to justify CPSU rule and Soviet policy, however, this doesn't mean that Marxism–Leninism was used as a means to an end. The relationship between ideology and decision-making was at best ambivalent, with most policy decisions taken in the light of the continued, permanent development of Marxism–Leninism. Marxism–Leninism, as the only truth, could not by its very nature become outdated.

Despite having evolved over the years, Marxism–Leninism had several central tenets. The main tenet was the party's status as sole ruling party. The 1977 Constitution referred to the party as the "leading and guiding force of Soviet society, and the nucleus of its political system, of all state and public organizations, is the Communist Party of the Soviet Union."State socialism was essential, and from Stalin until Gorbachev official discourse considered private social and economic activity as retarding the development of collective consciousness and of the economy. Gorbachev supported privatization to a degree, but based his policies on Lenin's and Bukharin's view on the New Economic Policy of the 1920s, and supported complete state ownership over the commanding heights of the economy. Unlike liberalism, Marxism–Leninism stressed not the importance of the individual, but rather the role of the individual as a member of a collective. Thus defined, individuals had only the right to freedom of expression if it safeguarded the interests of the collective. For instance, in the 1977 Constitution Marxism–Leninism it was stated that every person had the right to express their opinion, but that opinion could only be expressed if it was in accordance with the "general interests of Soviet society." In short, the amount of rights granted to an individual was decided by the state, and could be taken away by the state as it saw fit. Soviet Marxism–Leninism justified nationalism, and the media portrayed every victory of the Soviet Union as a victory for the communist movement as a whole. In large parts, Soviet nationalism was based upon ethnic Russian nationalism. Marxism–Leninism stressed the importance of the worldwide conflict between capitalism and socialism, and the Soviet press talked about progressive and reactionary forces, while claiming that socialism was on the verge of victory; that the "correlations of forces" were in the Soviet Union's favour. The ideology professed state atheism, and party members were not allowed to be religious. The state professed a belief in the feasibility of communist mode of production, and all policies were justifiable if it contributed to the Soviet Union's reaching that stage.
