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.
Austrian Empire
The French victories encouraged rulers of certain imperial territories to ally themselves with the French and assert their formal independence from the Empire. On 10 December 1805, Maximilian IV Joseph, the prince-elector and Duke of Bavaria, proclaimed himself King, followed by the Duke of Württemberg Frederick III on 11 December. Charles Frederick, Margrave of Baden, was given the title of Grand Duke on 12 December. Each of these new states became French allies. The Treaty of Pressburg between France and Austria, signed in Pressburg (today Bratislava, Slovakia) on 26 December, enlarged the territory of Napoleon's German allies at the expense of defeated Austria.
