From global to local and back: the ‘Third World’ concept and the new radical left in France

In the second half of the twentieth century, the transnational ‘Third World’ concept defined how people all over the globe perceived the world. This article explains the concept’s extraordinary traction by looking at the interplay of local uses and global contexts through which it emerged. Focusing on the particularly relevant setting of France, it examines the term’s invention in the context of the Cold War, development thinking, and decolonization. It then analyses the review Partisans (founded in 1961), which galvanized a new radical left in France and provided a platform for a communication about, but also with, the Third World. Finally, it shows how the association Cedetim (founded in 1967) addressed migrant workers in France as ‘the Third World at home’. In tracing the Third World’s local–global dynamics, this article suggests a praxis-oriented approach that goes beyond famous thinkers and texts and incorporates ‘lesser’ intellectuals and non-textual aspects into a global conceptual history in action.
