This article explores the ways in which French intellectuals understood the changing and intersecting relationships between France and Germany, France and Alsace-Lorraine, and France and Africa during the early twentieth-century expansion of the French empire. The body of the text analyzes the interdisciplinary discussions of Paul Desjardins, Charles Gide, and their academic and activist colleagues at the Union pour la vérité (Union for Truth) and its Libres entretiens (Open Conversations) in the immediate aftermath of the First and Second Moroccan Crises. Focusing on the Union's 1905–1906 and 1912–1913 debates over the issues of nationalism, internationalism, imperialism, and colonization provides a new understanding of the relationship between French national identity and French imperial identity. The conclusion explains how and why this group of largely progressive French political analysts simultaneously rejected German expansion into France and justified French expansion across the African continent.
