They became more of a fashionable item. most likely got more expensive so you'd only see the rich wearing shoes and it would show the social classes more easily so it might have made some people feel bad about themselfs. before they were only used to keep your feet from being burned from a hot ground or from getting frost bite in winter.
The Treaty of Versailles, signed in June 1919 at the Palace of Versailles in Paris at the end of World War I, codified peace terms between the victorious Allies and Germany. The Treaty of Versailles held Germany responsible for starting the war and imposed harsh penalties in terms of loss of territory, massive reparations payments and demilitarization. Far from the “peace without victory” that U.S. President Woodrow Wilson had outlined in his famous Fourteen Points in early 1918, the Treaty of Versailles humiliated Germany while failing to resolve the underlying issues that had led to war in the first place. Economic distress and resentment of the treaty within Germany helped fuel the ultra-nationalist sentiment that led to the rise of Adolf Hitler and his Nazi Party, as well as the coming of a World War II just two decades later.In a speech to Congress in January 1918, Wilson laid out his idealistic vision for the post-war world. In addition to specific territorial settlements based on an Entente victory, Wilson’s so-called Fourteen Points emphasized the need for national self-determination for Europe’s different ethnic populations. Wilson also proposed the founding of a “general association of nations” that would mediate international disputes and foster cooperation between different nations in the hopes of preventing war on such a large scale in the future. This organization eventually became known as the League of Nations.
