The postwar period caused divisions within parties and collective shifts between them, with some former left-wing movements, like the Radical Party, joining the center-right. Among the groups that explicitly claimed their liberalism in 1945–1947, the Parti Républicain de la Liberté (PRL) was the most active. It proudly sported the name of its program: neoliberalism. Formed in December 1945 in opposition to the Social Catholics (Mouvement Républicain Populaire, or MRP) and the communists, the PRL recruited both among the Resistance and among the former Petainists.
