The Liberation of France began with the Allied invasions of 1944, Operation Overlord at Normandy in the north and Operation Dragoon in the south. Allied forces achieved the Liberation of Paris in August. De Gaulle established the Provisional Government of the French Republic, and the entire country returned to the Allies. Further fighting occurred in France during the advance to the Rhine of 1944–1945. After the war, France became a founding member of NATO, and a permanent member of the United Nations Security Council.
