This collection presents exciting new research on the history of anarchist movements and their relation to organised labour, notably revolutionary syndicalism. Bringing together internationally acknowledged authorities as well as younger researchers, all specialists in their field, it ranges across Europe and from the late nineteenth century to the beginnings of the Cold War. National histories are revisited through transnational perspectives—on Britain, France, Italy, Germany, Poland or Europe as a whole—evidencing a great wealth of cross-border interactions and reciprocal influences between regions and countries. Emphasis is also placed on individual activist itineraries—whether of renowned figures such as Errico Malatesta or of lesser-known yet equally fascinating characters, whose trajectories offer fresh perspectives on the complex interplay of regional and national political cultures, evolving political ideologies, activist networks and the individual. The volume will be of interest to specialists working on the history of anarchism and/or trade unionism as well as the political or social history of the countries concerned; but it will also be useful to students and the general reader looking for discussion of the most recent thinking on the historiography of labour and anarchist movements or those wanting a comprehensive overview of the history of syndicalism.
