The digital collection Les marchés de guerre 14-18 [Markets during the First World War] has been created by the French Ministry of Economic Affairs and its Centre des Archives Économiques et Financières (CAEF) at Savigny-le-Temple. On this website you can chose particular themes concerning French industries and public works (Recherche thematique) or a particular location (Recherche géographique) using an interactive map. A national commission investigated between 1933 and 1940 the workings of markets during the First World War. The section Focus brings you to four dossiers on major firms such as Peugeot and Michelin. The section Sources gives you a chronological overview of French legislation and information about themes such as taxation and war finance. You can also read an essay with background information by Béatrice Touchelay (Université Lille-3). This digital collection can only be viewed in French.
The CAEF has also created a portal site concerning the First World War and the French economy.
