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.
Federal Constitutional Law (Austrian act)
When the 1919 Treaty of Saint Germain prohibited the union of Germany and Austria, Austria had to go to work on a permanent constitution in earnest, but was deeply divided on numerous issues. General elections on February 16, 1919 replaced the Provisional Assembly with a Constitutional Assembly ("Konstituierende Nationalversammlung"). The new parliament was dominated by Social Democrats, who favored a unitary state with a strong central government, and the Christian Social Party, who fought for a federation devolving significant authority to regional governments. Unable to reach consensus, the parties chose to defer the decision. The new constitution, passed on October 1 and formally published on October 5, 1920, stipulated that Austria was to be a parliamentary federal republic consisting of eight (at the time) federal states, but did not state which powers and duties would lie with the national government and which ones with the states.
