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.
Austria–Switzerland border
The current border is a product of the creation of the Helvetic Republic in 1798. During the 19th century it was part of the western border of the Austrian Empire and later Austria-Hungary, and in the 20th century of the First Austrian Republic, the Federal State of Austria, Nazi Germany and Allied-occupied Austria, and eventually of modern Austria since its formation in 1955. 
Liechtenstein was created as an independent principality under the Peace of Pressburg (1805), although it remained nominally a member of the Confederation of the Rhine until 1866).
