Third Republic of France (World War II)

See here for more on France in the wars The looming threat to France of Nazi Germany was delayed at the Munich Conference of 1938. France and Great Britain abandoned Czechoslovakia and appeased the Germans by giving in to their demands concerning the acquisition of the Sudetenland (the portions of Czechoslovakia with German-speaking majorities). Intensive rearmament programs began in 1936 and were re-doubled in 1938, but they would only bear fruit in 1939 and 1940.

Historians have debated two themes regarding the sudden collapse of the French government in 1940. One emphasizes a broad cultural and political interpretation, pointing to failures, internal dissension, and a sense of malaise that ran through all French society. A second one blames the poor military planning by the French High Command. According to the British historian Julian Jackson, the Dyle Plan conceived by French General Maurice Gamelin was destined for failure, since it drastically miscalculated the ensuing attack by German Army Group B into central Belgium. The Dyle Plan embodied the primary war plan of the French Army to stave off Wehrmacht Army Groups A, B, and C with their much revered Panzer divisions in the Low Countries. As the French 1st, 7th, 9th armies and the British Expeditionary Force moved in Belgium to meet Army Group B, the German Army Group A outflanked the Allies at the Battle of Sedan of 1940 by coming through the Ardennes, a broken and heavily forested terrain that had been believed to be impassable to armoured units. The Germans also rushed along the Somme valley toward the English Channel coast to catch the Allies in a large pocket that forced them into the disastrous Battle of Dunkirk. As a result of this brilliant German strategy, embodied in the Manstein Plan, the Allies were defeated in stunning fashion. France had to accept the terms imposed by Adolf Hitler at the Second Armistice at Compiègne, which was signed on 22 June 1940 in the same railway carriage in which the Germans had signed the armistice that ended the First World War on 11 November 1918.

The Third Republic officially ended on 10 July 1940, when the French parliament gave full powers to Marshal Philippe Pétain, who proclaimed in the following days the État Français (the "French State"), commonly known as the "Vichy Regime" or "Vichy France" following its re-location to the town of Vichy in central France. Charles de Gaulle had made the Appeal of 18 June earlier, exhorting all French not to accept defeat and to rally to Free France and continue the fight with the Allies.

Throughout its seventy-year history, the Third Republic stumbled from crisis to crisis, from dissolved parliaments to the appointment of a mentally ill president (Paul Deschanel). It fought bitterly through the First World War against the German Empire, and the inter-war years saw much political strife with a growing rift between the right and the left. When France was liberated in 1944, few called for a restoration of the Third Republic, and a Constituent Assembly was established by the government of a provisional French Republic to draft a constitution for a successor, established as the Fourth Republic (1946 to 1958) that December, a parliamentary system not unlike the Third Republic.
