What's the difference between Marxism and Communism?
gpt
Marxism is a collection of philosophical, political and socioeconomic schools of thought, commonly employing Marx's analysis tools of historical materialism, his critique of capitalism, and Marxian theories of economics. 

In Marxist philosophy, a Communist society is a classless, stateless and moneyless society where the means of production are commonly owned by the workers. Communists seek to achieve this form of society, generally through the abolishing of capitalism through a worker led revolution. There are many forms of communism, and most communist states claim to follow some form of Marxist ideology (most notably Marxism-Leninism), but there are other non-Marxist communist ideologies.

So Communism is a collection of ideologies concerned with achieving a communist society, while Marxism is a philosophical and economic framework employed by communists and socialists, though not exclusively.
