Discover the 1918 Austrian-Yugoslav Border Conflict Exhibition at the House of Austrian History

This content details the Austrian-Yugoslav border conflict that began in 1918, focusing on the development of the 'Carinthian Defense Campaign' and the 1920 plebiscite. It outlines the territorial disputes and military engagements between Austria and the SHS State, leading to the crucial vote that determined the border.

The content delves into the contested border between Carinthia and the State of Slovenes, Croats and Serbs (SHS State) from 1918 to 1920. It describes the initial territorial claims by the SHS State in November 1918, following Carinthia's decision to join the Republic of German-Austria. The text highlights the Carinthian provincial government's decision to resist militarily, with unofficial support from the young republic due to its reliance on food supplies from the SHS State. A ceasefire and a visit by the US Miles Mission led to a provision for a plebiscite in southern Carinthia in the Treaty of Saint Germain. Despite this, fighting continued, with Carinthian forces recapturing occupied areas, though Klagenfurt was occupied in June 1919 and later evacuated. The text notes over 200 casualties. The plebiscite, held on October 10, 1920, in Zone A resulted in a 59% vote for remaining with Austria, with a notable proportion of Slovene speakers voting for Austria.
