The idea of Austrian territories with a significant German-speaking population joining a Greater German state was maintained by some circles both in Austria-Hungary and Germany. It was again promoted after the close of World War I and the dissolution of the Austro–Hungarian monarchy in 1918 by the proclamation of the rump state German Austria. Proponents attempted to incorporate German Austria into the German Weimar Republic; however, this was prohibited by the terms of both the Treaty of Saint-Germain and the Treaty of Versailles, though the major Austrian political parties such as the Greater German People's Party or the Social democrats pursued this idea regardless.
