Following the defeat in World War I, the influence of German-speaking elites over Central and Eastern Europe was greatly limited. At the Treaty of Versailles, Germany was substantially reduced in size. Austria-Hungary was split up. A Rump-Austria, which to a certain extent corresponded to the German-speaking areas of Austria-Hungary (a complete split into language groups was impossible due to multi-lingual areas and language-exclaves) adopted the name "German Austria" () in hope for union with Germany. Union with Germany and the name "German Austria" was forbidden by the Treaty of St. Germain and the name had to be changed back to Austria.
