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.
Austria under National Socialism
On 12 February 1934 there was a violent confrontation in Linz with serious consequences. Members of a paramilitary group acting to assist the police wanted to enter a building belonging to the Social Democrats or a party member's home. They wanted to find any weapons belonging to the Social Democrat paramilitary which had by then been banned. Violence spread to the whole country and developed into civil war. The police and their paramilitary supporters together with the army won the confrontation by the 14 February. There were many arrests. Constitutional courts were abolished, trade unions and the Social Democrat Party were banned, and the death penalty was reintroduced. After political opposition had been suppressed the Austrian Republic was transformed into the Austrofacist "Ständestaat". The authoritarian "Maiverfassung" (May Constitution) was proclaimed on 1 May.
