I became interested in anarchism by reading books about the Spanish Civil War. The first real anarchist I met was Murray Bookchin at a conference in Ann Arbor in 1969. Bookchin understood that many student radicals were anarchists in practice, even if they called themselves Marxists, so he emphasised the libertarian elements of Marx in his propaganda.
