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.
History of Austria
Although the Treaty of Versailles and the Treaty of St. Germain had explicitly forbidden the unification of Austria and Germany, the native Austrian Hitler was vastly striving to annex Austria during the late 1930s, which was fiercely resisted by the Austrian Schuschnigg dictatorship. When the conflict was escalating in early 1938, Chancellor Schuschnigg announced a plebiscite on the issue on 9 March, which was to take place on 13 March. On 12 March, "German troops entered Austria", who met celebrating crowds, in order to install Nazi puppet Arthur Seyss-Inquart as Chancellor. With a Nazi administration already in place the country was now integrated into the Third Reich and renamed as "Ostmark" until 1942, when it was renamed again as "Alpen-und Donau-Reichsgaue" ("Alpine and Danubian Gaue"). A rigged referendum on 10 April was used to demonstrate the alleged approval of the annexation with a majority of 99.73% for the annexation.
