The ideology stemming from writers; Marx, Engels, Lenin.
MLs believe that a successful socialist revolution needs a vanguard party and that there needs to be a transitionary period where the bourgeosie are oppressed out of existance. This usually occurs through the seizure of private property, nationalization of industry, and bourgeois culture. The proleteriat via the vanguard party will create a workers state which will implement all of what's said above. Eventually the state will whither away as it becomes less needed usually when the threat of counter revolutionary behavior is gone, and then we will have communism, a stateless, classless, moneyless society.
You know MLs aren't red fascists right? They were instrumental in defeating them.
I am a Marxist-Leninist some of my favorite works are State and Rev and Imperialism by Lenin, along with Principles of Communism, and German Ideology.
