The purpose of Marxism–Leninism is to turn a capitalist state into a socialist state. This is done by a revolution by the proletariat to overthrow the old government. The new government then creates a "dictatorship of the proletariat". This new government leads the country based on democratic centralism.[2][3]
The communist party is supposed to lead society from capitalism to socialism. According to ML, socialism was more "advanced" than capitalism, but communism would be more "advanced" than socialism. Indeed, ML is supposed to provide only a first step: from capitalism to socialism, on the way to a communist society with no class or state..
