The crisis of Marxism in the late twentieth century was the crisis
of orthodox and vanguardist Marxism associated mainly with
hierarchical communist parties, and which was imposed – even
as state ideology – as the ‘correct’ Marxism. The Stalinisation of
the Soviet Union and its eventual collapse exposed the inherent
weaknesses and authoritarian mould of vanguardist Marxism.
More fundamentally, vanguardist Marxism was rendered obsolete
but for its residual existence in a few parts of the world, including
authoritarian national liberation movements in Africa and in China.
