In the essays that make up this book, Murray Bookchin places the Spanish anarchist and anarcho-syndicalist movements of the 1930s in the context of revolutionary worker's movements of the pre-World War II era. These articles describe, analyze, and evaluate the last great proletarian revolution of the past two centuries. They form indispensable supplements to Bookchin's larger work, The Spanish Anarchists: The Heroic Years, 1868–1936. Read together, these works constitute a highly informative and theoretically significant assessment of the anarchist and anarcho-syndicalist movements in Spain. They are invaluable for any reader concerned with the place of the Spanish Revolution in history and with the accomplishments, insights, and failings of the anarcho-syndicalist movements.
