'Leninism'

'Leninism - the scientific basis of the Party's policy'

After the October Revolution of 1917 Leninism was the ideological basis of Soviet Socialism. It enetered common usage in 1922.

If Soviet Russia was Marxist-Leninism, China is Market-Leninism. In other words, communist; China has a one party system and that party is communists, but the focus is not on isolation. Soviet Russia had no interest to compete in the global market, where China is Market-Leninism, they compete in the global market and remain communist or follow the teachings of V.I. Lenin.

Many pure Marxists are not happy with the overall acceptance of Leninism and its acceptance within the dogma of Marxism-Leninism. The primary criticism by pure Marxists on Leninism is that Lenin was so flexible that it allows his followers to justify almost any policy by sifting through Lenin's various policies and finding one that suits a policy supported by Marxism-Leninism.

Communism is synonymous with Marxist-Leninism.
