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.
Treaty of Saint-Germain-en-Laye (1919)
Article 88 of the treaty required Austria to refrain from directly or indirectly compromising its independence, which meant that Austria could not enter into political or economic union with the German Reich without the agreement of the council of the League of Nations. Accordingly, the new republic's initial self-chosen name of German-Austria () had to be changed to Austria. Many Austrians would come to find this term harsh (especially among the Austrian Germans who were German nationalists of the former Austro-Hungarian Empire), due to Austria's later economic weakness, which was caused by loss of land. The economic weakness of Austria would later lead to support for the idea of "Anschluss" (political union) with Nazi Germany.
