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.
Allied-occupied Austria
On 20 April 1945, the Soviets, without asking their Western allies, instructed Renner to form a provisional government. Seven days later Renner's cabinet took office, declared the independence of Austria from Nazi Germany and called for the creation of a democratic state along the lines of the First Austrian Republic. Soviet acceptance of Renner was not an isolated episode; their officers re-established district administrations and appointed local mayors, frequently following the advice of the locals, even before the battle was over.
Renner and his ministers were guarded and watched by NKVD bodyguards. One-third of State Chancellor Renner's cabinet, including crucial seats of the Secretary of State of the Interior and the Secretary of State for Education, was staffed by Austrian Communists. The Western allies suspected the establishment of a puppet state and did not recognize Renner. The British were particularly hostile; even Harry Truman, who believed that Renner was a trustworthy politician rather than a token front for the Kremlin, denied him recognition. But Renner had secured inter-party control by designating two Under-Secretaries of State in each of the ministries, appointed by the two parties not placing the Secretary of State.
