In particular the "Carinthian question" had become an issue in the closing days of World War I, when events developed rapidly, beginning with territorial claims by the Slovenian National Assembly on October 17, 1918. These claims were rejected by the Carinthian provisional "Landtag" assembly on 25 October 1918, declaring the state's accession to German-Austria. From November 5, Yugoslav forces moved into the settlement area of the Carinthian Slovenes from the Karawanks mountain range down to the Drava River and beyond. The "Landtag" assembly fled from Klagenfurt to the northwestern town of Spittal an der Drau and on 11 November officially demanded self-determination, which in this case amounted to demanding a plebiscite for a region with a mixed population.
