This book, the first English-language history of the French revolutionary group Socialism ou Barbarie, focuses on the period of 1949 to 1957 when the influence of the group began to wane. Hastings-King explains why Socialisme ou Barbarie’s anti-Leninist position on organization led it to privilege first person narratives in order to understand worker experience and its revolutionary possibilities. Looking for the Proletariat draws on these narratives-the only first-person accounts of the working-class experience in French industry during the 1950s-to explore the disintegration of collective investment in the Marxist Imaginary that unfolded at Renault’s Billancourt factory in the aftermath of the Hungarian Revolution.
