Austria Alemana
After submitting a formal note of protest to the Allies against blocking German-Austrian union, on 10 September 1919 Renner signed the Treaty of Saint Germain and it was ratified by the Constituent National Assembly on 17 October. According to its provisions, on 21 October the country changed its official name from "Republic of German-Austria" to "Republic of Austria". It also lost the Sudetenland and German Bohemia to Czechoslovakia, South Tyrol and Istria (including the Adriatic port of Trieste) to the Kingdom of Italy, and Carniola, Lower Styria and Dalmatia to the Kingdom of Serbs, Croats, and Slovenes.
