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.
