Marxism

n. a philosophical position and economic theory drawn directly or indirectly from the works of Karl Marx.

Marxism has spawned, or been appropriated by, a number of social revolutionary and communitarian movements, including communism. See also class theory; dialectical materialism. —Marxist adj., n.
