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.
