MARX and Marxism

Karl Marx probably had more influence on the political course of the last century than any other social thinker. There are many different kinds of Marxism, and the Twentieth Century saw two huge Marxist states in total opposition to one another. In the West, Marxism has never presented a revolutionary threat to the established order, though it has taken root as the major theoretical critique of capitalist society in intellectual circles, and new interpretations of Marx's thought appear each year.
