On the occasion of the 130th anniversary of the Commune of Paris a new book has been published in French on this thematic: “Révolution et contre-Revolution à Paris en 1870-1871″. This book does not come from official researchers and historians, on the contrary, it is a product of critics from the revolutionary movement of our class and describes the forces and weaknesses of this important episode in the life of the proletariat. We received and we publish here an English extract from the most interesting parts of the book.
