Communism is a revolutionary socialist movement to create a classless, moneyless, and stateless social order structured upon common ownership of the means of production, as well as a social, political, and economic ideology that aims at the establishment of this social order.
Marxist theory holds that pure communism or full communism is a specific stage of historical development that inevitably emerges from the development of the productive forces that leads to a superabundance of material wealth, allowing for distribution based on need and social relations based on freely associated individuals. The exact definition of communism varies, and it is often mistakenly, in general political discourse, used interchangeably with socialism; however, Marxist theory contends that socialism is just a transitional stage on the road to communism. Leninism adds to Marxism the notion of a vanguard party to lead the proletarian revolution and to secure all political power after the revolution for the working class, for the development of universal class consciousness and worker participation, in a transitional stage between capitalism and communism.
Council communists and non-Marxist libertarian communists and anarcho-communists oppose the ideas of a vanguard party and a transition stage, and advocate for the construction of full communism to begin immediately upon the abolition of capitalism. There is a very wide range of theories amongst those particular communists in regards to how to build the types of institutions that would replace the various economic engines (such as food distribution, education, and hospitals) as they exist under capitalist systems—or even whether to do so at all. Some of these communists have specific plans for the types of administrative bodies that would replace the current ones, while always qualifying that these bodies would be decentralised and worker-owned, just as they currently are within the activist movements themselves. Others have no concrete set of post-revolutionary blueprints at all, claiming instead that they simply trust that the world’s workers and poor will figure out proper modes of distribution and wide-scale production, and also coordination, entirely on their own, without the need for any structured “replacements” for capitalist state-based control.
