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.
Aftermath of World War II
The Federal State of Austria had been annexed by Germany in 1938 (Anschluss, this union was banned by the Treaty of Versailles). Austria (called Ostmark by the Germans) was separated from Germany and divided into four zones of occupation. With the Austrian State Treaty, these zones reunited in 1955 to become the Republic of Austria.
