"Written in 1938, this is a classic introduction to its subject. Rocker was a prominent anarcho-syndicalist himself and his account of the origins of the labour movement, the fore-runners of syndicalism, and the objectives, methods and evolution of anarcho-syndicalism is therefore authoritative. He prefaces his account of anarcho-syndicalism with a description of the aims and purposes of anarchism and this edition has, as an appendix, the first chapter of Rocker's biography, London Years."
