When France went to war with Germany in 1939, Doriot became a staunch pro-German and supported Germany's occupation of northern France in 1940. Doriot resided in collaborationist Vichy France for a time, but he eventually found that it was not nearly as Fascist as he had hoped it would be and moved to occupied Paris, where he espoused pro-German and anti-communist propaganda on Radio Paris. In 1941, he and fellow fascist collaborator Marcel Déat founded the Légion des Volontaires Français (LVF), a French unit of the Wehrmacht.
