What impact did World War 1 have on France?

Answer 1

France annexed the Independent Republic of Alsace-Lorraine, the country which had been established in the wake of Kaiser Wilhelm II's abdication, corresponding to the region which had been ceded to the German Empire during the 1870 Franco-Prussian War. At the 1919 Peace Conference, Prime Minister Clemenceau's aim was to ensure that Germany would not seek revenge in the following years. To this purpose, the chief commander of the Allied forces, Field Marshal Ferdinand Foch, had demanded that for the future protection of France the Rhine river should now form the border between France and Germany. Based on history, he was convinced that Germany would again become a threat, and, on hearing the terms of the Treaty of Versailles that had left Germany substantially intact, he observed that "This is not Peace. It is an Armistice for twenty years."
