GermanAustria

German Austria, or Deutschösterreich, was a short-lived post-imperial state formed from the German-speaking lands of Cisleithania after the Austro-Hungarian Empire dissolved in 1918. It proclaimed the Republic of German Austria on 12 November 1918 in Vienna.

It operated as a parliamentary democracy under leaders such as Karl Renner, and a 1919 constitution asserted the republic and its goal of eventual unification with Germany.

Its territory encompassed most former crown lands of Cisleithania: Lower and Upper Austria, Styria, Carinthia, Tyrol, Salzburg, and Vorarlberg; Burgenland joined Austria after border adjustments in the early 1920s, and wartime changes left unsettled boundaries.

The Treaty of Saint-Germain-en-Laye (1919) forbade the annexation of Austria with Germany, limiting Deutschösterreich's ambitions and shaping postwar borders.

In 1920 the state transitioned to the official name Republik Österreich (Republic of Austria), with the old Deutschösterreich designation gradually falling from formal use. Austria remained independent until its 1938 Anschluss with Nazi Germany; sovereignty was restored in 1955.

In historical contexts, German Austria refers to this early post-imperial stage and its unification aspirations; the modern state is the republic of Austria, a neutral federal republic.
