Both Marxism and anarchism come out of the 19th century workers’ and socialist movements. They shared certain goals: the end of classes and of capitalism, the end of the state, and of all oppression. They believed that these goals would be achieved through the international revolution of the working class, in alliance with all oppressed sections of society. They both advocated the formation of labor unions (their practical dispute was over whether to also form electoral workers’ parties). And they both have been historical failures, in that neither has led to successful, lasting, working class revolutions—so far. Yet they have been at odds since the bitter faction fight which blew up the First International, between the forces led by Karl Marx and those of Michael Bakunin, primary founder of anarchism as a movement.
