ABSTRACT
World War I had a dramatic impact on the culture and society of the postwar decade. Changes in almost every area of life provided a sense that a new era had begun and that the world would never be the same. The war damaged people's faith in progress, reason, and democracy. The changes that Europe experienced in the 1920s turned out to be an extension of changes that had already begun during the war itself. The war had served as a solvent of class distinctions and gender barriers, accelerating the transition to a society that would radically differ from that of even the late nineteenth century. New technologies helped to shape the changing culture and social atmosphere of the postwar world. In 1923 the Allies negotiated the final peace settlement resulting from the war in the Treaty of Lausanne with the new Turkish Republic.
