Bolshevism and the Labour Movement [PDF ebook] 

Originally published in 1916, this volume discusses the history of the labour movement during the latter part of the 19th and early part of the 20th centuries, in so far as it relates to the advocacy and use of violence. A contentious issue which divided the labour movement during the 19th century, the author presents arguments made by both sides of this controversy. Nonetheless, the book remains a Marxist critique of violence as practised by direct action anarchists.
