The Mass Strike, the Political Party and the Trade Unions was written in 1906 by Polish-born revolutionary Rosa Luxemburg. It brilliantly captures the fundamental lessons from the experience of mass workers' strikes and their role in the 1905 Russian Revolution. Luxemburg lived in a world in crisis - one characterised by the fast approach of the First World War - and in an era when revolutionary struggles and ideas broke out internationally. Now, over a century later, capitalism is lunging deeper into a crisis of mammoth economic, political, social and ecological proportions. The need for mass strikes that can spill over into revolution is now existential. In this short book, Luxemburg shows how strikes call into question the relationship between the working class and the employing class, how political and economic demands fuse in the course of such strikes, and how they can start to challenge the conservative approach of the trade union leaders. Her book is as relevant as ever in helping course the path to a revolution that can smash capitalism and build another world.
