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.
Government of Austria
After the dissolution of the Austro-Hungarian Monarchy, on 30 October 1918 the provisional national assembly of German Austria elected a State Council ("Staatsrat") executive, which itself appointed a state government with the Social Democratic politician Karl Renner as head of the State Chancellery. The Renner ministry was composed of representatives of the three main political parties—Social Democrats, the Christian Social Party (CS) and German Nationalists (Greater Germans)—according to the "Proporz" doctrine. As acting executive body it remained in office until the Constitutional Assembly of the Austrian First Republic on 15 March 1919 elected Renner's second cabinet, a coalition government of Social Democratic and Christian Social ministers.
