What was the goal of the communist revolution?

A communist revolution is a proletarian revolution often, but not necessarily inspired by the ideas of Marxism that aims to replace capitalism with communism, typically with socialism as an intermediate stage.

Some Marxists disagree with the idea of a vanguard as put forth by Lenin, especially left communists. Some who continue to consider themselves Marxist–Leninists also oppose the vanguard despite disagreeing with the majority of left communism. These critics insist that the entire working class or at least a large part of it must be deeply involved and equally committed to the socialist or communist cause in order for a proletarian revolution to be successful.
