Luxemburgism is a variant of Marxist revolutionary theory based on the writings of Rosa Luxemburg. According to M. K. Dziewanowski, the term was originally coined by Bolshevik leaders denouncing the deviations of Luxemburg's followers from traditional Leninism, but it has since been adopted by her followers themselves.
Luxemburgism is a Marxist tendency within Libertarian Marxism which, while supporting the Russian Revolution, as Luxemburg did, agrees with her criticisms of the politics of the Bolsheviks.
