Austria
The Treaty of Saint-Germain of 1919 (for Hungary the Treaty of Trianon of 1920) confirmed and consolidated the new order of Central Europe which to a great extent had been established in November 1918, creating new states and altering others. The German-speaking parts of Austria which had been part of Austria-Hungary were reduced to a rump state named The Republic of German-Austria (German: "Republik Deutschösterreich"). The desire for "Anschluss" (annexation of Austria to Germany) was a popular opinion shared by all social circles in both Austria and Germany. On 12 November, German-Austria was declared a republic, and named Social Democrat Karl Renner as provisional chancellor. On the same day it drafted a provisional constitution that stated that "German-Austria is a democratic republic" (Article 1) and "German-Austria is an integral part of the German reich" (Article 2). The Treaty of Saint Germain and the Treaty of Versailles explicitly forbid union between Austria and Germany. The treaties also forced German-Austria to rename itself as "Republic of Austria" which consequently led to the first Austrian Republic.
Republic of German-Austria
On 13 November 1918, German-Austria asked Germany to start negotiations of union and on 15 November sent a telegram to President Wilson to support union of Germany and Austria. This was grounded in the view that Austria had never been a nation in the true sense. While the Austrian state had existed in one form or another for over 700 years (dating to the Holy Roman Empire), its only unifying force had been the Habsburgs. Apart from being German-inhabited, these Lands had no common "Austrian" identity. They were Habsburg-ruled lands that had not joined the Prussian-dominated German Empire after the Austrian Empire lost the Austro-Prussian War.
