*Le Parti socialiste entre Résistance et République* is a historical and political study of the French Socialist Party during the transition from the wartime Resistance to the restored republican order. The work examines how socialist politics, institutions, and party organization adapted to the challenges of postwar France, including reconstruction, electoral competition, ideological debate, and the reshaping of republican life. With attention to the Parti socialiste-S.F.I.O., it situates the party within broader currents of French political history and considers its efforts to define a role between inherited socialist traditions and the practical demands of governing in a democratic republic. This volume is intended for readers interested in modern French politics, socialist movements, and the institutional development of parties in twentieth-century France.
