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.
History of the Social Democratic Party of Austria
By October, a provisional national assembly ("Provisorische Nationalversammlung") was convened under the Social Democrat Karl Renner, which tried to work out a provisional constitution ("Provisorische Verfassung") under the leadership of a new state council led by the new state chancellor Renner. The Social Democrats wanted a new form of government and, on 12 November 1918, the republic was proclaimed by Renner. Renner's government introduced an eight-hour workday and paid holidays.
