Austria
The status of South Tyrol was a lingering problem between Austria and Italy until it was officially settled by the 1980s with a great degree of autonomy being granted to it by the Italian national government. Between 1918 and 1919, Austria was known as the State of German Austria (). Not only did the Entente powers forbid German Austria to unite with Germany, but they also rejected the name German Austria in the peace treaty to be signed; it was, therefore, changed to Republic of Austria in late 1919.
Anschluss
Elite and popular opinion in Austria after 1918 largely favored some sort of union with Germany, but it was explicitly forbidden by the peace treaties. The Austro-Hungarian Empire broke up in 1918, and on 12 November that year German Austria was declared a republic. The provisional national assembly drafted a provisional constitution that stated that "German Austria is a democratic republic" (Article 1) and "German Austria is a component of the German Republic" (Article 2). Later plebiscites in the German border provinces of Tyrol and Salzburg yielded majorities of 98% and 99% in favor of a unification with the German (i.e. Weimar) Republic.
