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.
Austrians
The creation of the Czecho-Slovak and South Slav states, the dissolution of the real union with Hungary, and the post-war treaties imposed by the victorious Allies combined to see the newly established Austrian republic both with the boundaries it has today, and a largely homogeneous German-speaking population. In the Treaty of Saint-Germain, in September 1919 the union with Germany was prohibited, and the new republic's name "Deutschösterreich" was prohibited by the treaty; instead the term "Republic of Austria" was used. The westernmost province Vorarlberg's wish to unite with Switzerland was also ignored. On October 21, 1919, the state changed its name accordingly. Many German Austrian communities were left scattered throughout the other new states, especially in Czechoslovakia, where more than 3 million German Bohemians had not been allowed to become part of the new Austrian state, as well as in the southern part of Tyrol which now found itself part of Italy. In total, more than 3.5 million German-speaking Austrians were forced to remain outside the Austrian state.
