History of Austria
Austria was dominated by the House of Habsburg and House of Habsburg-Lorraine ("Haus Österreich") from 1273 to 1918. In 1808, when Emperor Francis II of Austria dissolved the Holy Roman Empire, Austria became the Austrian Empire, and was also part of the German Confederation until the Austro-Prussian War of 1866. In 1867, Austria formed a dual monarchy with Hungary: the Austro-Hungarian Empire (1867–1918). When this empire collapsed after the end of World War I in 1918, Austria was reduced to the main, mostly German-speaking areas of the empire (its current frontiers), and adopted the name The Republic of German-Austria. However the union and name were forbidden by the Allies at the Treaty of Versailles. This led to the creation of the First Austrian Republic (1918-1933).
Carinthia
In late 1918, it became obvious that the breakup of the crumbling Habsburg monarchy was imminent, and on 21 October 1918 the members of the Reichsrat for the German-speaking territories of Austria met in Vienna to constitute a "Provisional National Council for German-Austria". Prior to the meeting the delegates agreed that German-Austria should not include "Yugoslav areas of settlement", which referred to Lower Styria and the two Slovene-speaking Carinthian valleys south of the Karawanken range, Seeland (Slovenian: Jezersko) and "Mießtal" (the valley of the Meža River). On 12 Nov. 1918, when the Act concerning the foundation of the State of German-Austria was formally passed by the Provisional National Assembly in Vienna this was worded by the State Chancellor, Karl Renner, "...to encounter the prejudices of the world as though we wanted to annex alien national property" The day before, on 11 Nov. 1918 the Provisional Diet of Carinthia had formally declared Carinthia's accession to the State of German-Austria. The Federal Act concerning the Extent, the Borders and the Relations of the State Territories of 22 Nov. 1918 then clearly stated in article 1: "...the duchies of Styria and Carinthia with the exclusion of the homogenous Yugoslav areas of settlement". Apart from one Social-Democrat, Florian Gröger, all the other delegates from Carinthia—Hans Hofer, Jakob Lutschounig, Josef Nagele, Alois Pirker, Leopold Pongratz, Otto Steinwender, Viktor Waldner—were members of German national parties and organizations.
