In the aftermath of the First World War, there was an Austro-Slovene conflict in Carinthia in which ethnic Slovenes and ethnic Germans (Austrians) fought for control of the linguistically mixed region between Styria and Carinthia. The Slovenes were loyal to the newly formed Kingdom of Serbs, Croats and Slovenes (later Yugoslavia), while the Austrians were loyal to the newly proclaimed Republic of German Austria. The disputed territory had belonged to the Austro-Hungarian empire. At the centre of conflict was the position of the border that separated the two new states. In Slovene-language historiogaphy, the conflict is known as the Boj za severno mejo ("battle for the northern border"),[4][5] while in German-language historiography it is the Kärntner Abwehrkampf ("Carinthian defensive struggle").

Background

Slovene-speaking regions were integrated into several Austrian states throughout much of the 2nd millennium. The idea of South Slavic–speaking territories creating a new state of their own has been one of the key issues debated among Slovene intelligentsia throughout the second part of the 19th century, especially in the aftermath of the spring of nations. As a consequence of Austro-Hungarian invasion of Serbian Kingdom the Yugoslav committee was formed, with its goal being the unification of South Slavic lands known as Yugoslavia. In 1916 the Serbian parliament in exile voted in favour of creating a Kingdom of Yugoslavia as a plan of post-world war governance of the Balkan peninsula.[6]

Creation of the State of Slovenes, Croats and Serbs

As a consequence of the World War, the Austro-Hungarian Empire began to dissolve even before an official end to war was declared. In period between 5–8 October 1918 a pro-Yugoslav National Council of Slovenes, Croats and Serbs took control over the regional administration in Zagreb. On 29 October the National Council declared the formation of a Yugoslav state, following a rejection of a plan of greater autonomy within Austria-Hungary. Entente powers did not recognise the newly found state before it merged with Kingdom of Serbia only three days later in an effort to gain a stable and recognised country of all South Slavs, as well as discouraging Italy from conquering Slav-settled territory not accounted as war reparation to Italy in Treaty of London.[7]

Territorial claims

No formal border was yet recognised among the newly created entities, with both sides claiming that they are in control of the area along the ethnically mixed settlements.[8] The National Government in Ljubljana did not pay any particular attention to the border issue, as it was planning on gaining much area through negotiations on the peace conference. The municipal council of the largely German-speaking town of Maribor (Marburg an der Drau) declared the municipality to be a part of German-Austria on 30 October 1918.[9]

Escalation

Mobilization

The National Council for Styria (Slovene: Narodni svet za Štajersko) gave permission to take control of the military branch in Maribor to Rudolf Maister, a veteran of the World War and a former officer of Austria-Hungary. He also gained the rank of a General, and was given authority over all military forces located in Styria under control of the Kingdom of SHS.[10] On October 31 Rudolf Maister announced his disagreement[11] with the municipal declaration of Maribor in front of an audience of Lieutenant Colonel Anton Holik and his officers at the Melj military barracks of the 26th infantry regiment. On 9 November Maister announced full mobilization of Lower Styria, which was disagreed with by both, the German-Austrian government and authorities in Ljubljana. The mobilization decree was successful as the armed forces grew to about 4,000 fighters, and establishing a new infantry regiment in Maribor by November 21.[12]

Military movements begin

First Lieutenant Franjo Malgaj and his unit entered Carinthia on November 6. Captain Alfred Lavrič's unit was designated to be in charge of capturing Carinthia, and began taking control of the territory on 13 November, when his units entered the Jaun Valley (German: Jauntal, Slovene: Podjuna) and Ferlach (Slovene: Borovlje). The Loibl Pass (German: Loiblpass, Slovene: prelaz Ljubelj) was captured the following day.[13]

On November 23 Maister's fighters began to seize control of guard posts throughout the Maribor region by disarming the local guardsmen controlled by the Maribor municipality. Captain Rudolf Knez entered Sittersdorf (Žitara vas) and settled his units there. From November 27 onward, the Slovene fighters under direct command of Maister, took control of Spielfeld (Špilje), Bad Radkersburg (Radgona), Mureck (Cmurek), Leutschach (Lučane), Marenberg (now Radlje ob Dravi), and Muta (Hohenmauthen), while the units from Celje under command of Franjo Malgaj took control of the Meža Valley (Mießtal), Bleiburg (Pliberk), where Serb volunteers returning from the Eastern front of World War I also joined Malgaj's unit. All the areas captured were agreed upon by General Rudolf Passy of Carinthia and General Maister on November 27. The agreement included allowance to take control of all Slovene-majority settlements, but remained unsupported and criticized by Styrian, Carinthian, German-Austrian authorities, as well as the National council in Ljubljana. Units from Ljubljana took control of Dravograd (Unterdrauburg), Lavamünd (Labot) and Sankt Paul (Šentpavel).[12] The capture of Völkermarkt (Velikovec) on November 30 sparked much criticism, as it allegedly wasn't included in the demarcation line plans.[14]

Armed conflicts

Result of a clash between Austrian Carinthian units and Maister's fighters on the northern side of the Karawanks Tunnel

First armed clashes already occurred under command of Malgaj during the attack on Bleiburg, but it was not until the battle in Lučane when violent confrontations became apparent. Lučane was the site of a first major clash between the two factions on January 14, 1919. Following minor fights between the two militias, a larger battle occurred on February 4 near Radgona.[15] Plans were set by Maister to attack and capture Klagenfurt (Celovec) but were abandoned following negotiations. On February 13 a peace treaty was signed by both parties.

Graz-Ljubljana Protocol

With the occupation of southeastern Carinthia by Yugoslav troops, and the confrontation evolving into armed clashes, the provisional Carinthian government under Governor Arthur Lemisch decided to lead off the armed struggle in order to preserve the southern Carinthian border on the Karawanks. Bitter fighting of paramilitary groups around Arnoldstein and Ferlach alarmed the Entente powers. They arbitrated a ceasefire, whereafter a nine-day U.S. Army commission under Lt. Col. Sherman Miles scouted the disputed region between river and mountains in January and February 1919 and made the crucial recommendation that the Karawanks frontier should be retained, thus opening the possibility of a plebiscite. Yugoslav representatives urged for a border on the Drava; American delegates however spoke in favor of preserving the unity of the Klagenfurt Basin and convinced the British and French delegations to support their plan of plebiscite for the entire Klagenfurt region.

Yugoslav offensive and Austrian counter-offensive

On April 29, Yugoslav troops breached ceasefire agreement after months of relative peace. Armed clashes occurred throughout the region, with noticeable territorial gains achieved by Kingdom of Serbs, Croats and Slovenes. The Yugoslav troops experienced much resistance in the following days, as Austrian troops already made effective counter-offensive actions. The situation for Slovenes worsened, and on the 2nd of May Carinthian units had already taken control of Völkermarkt. Two days later Austrian counter-offensive reached the Gallizien(Slovene: Galicija)-Apače (German: Abstall)-Sankt Margareten im Rosental (Šmarjeta) line. After two days of fierce fighting the German-Austrian units successfully conquered the line and in process destroyed the 3rd infantry battalion from Ljubljana.

The remaining Slovene units continued to retreat back into lower Styria, while almost all of the Carinthian area that was gained during the winter clashes was lost to the advancing Austrian units. The last to fall was Dravograd before the Royal Yugoslav Army's 36th infantry regiment under control of Lt.Col. Vladimir Uzorinac managed to hold ground in Guštanj (Gutenstein in Kärnten) and therefore stop the counter-offensive. General Maister sent two units of his Maribor infantry regiment to aid the troops holding ground near Slovenj Gradec.[16] Officer Malgaj was killed on 6 May, one of the key leaders of the Slovene fighters in Carinthia.

After a military defeat in the offensive initiated in April, authorities in Ljubljana mobilised all their assets and drafted regiments from Serbia to regain lost territory. On May 26 a new offensive was authorised which lasted throughout May and until June 6, during which they managed to capture much of the Klagenfurt region to as north as Maria Saal (Gospa Sveta). The offensive was considered a military success.[17]

Aftermath

The Paris peace conference turned the tide when an order was given to the Yugoslavs to completely retreat from the northern B zone of the Klagenfurt Basin area in a time frame set to end on the 31st of July, at the latest, to enable the commission to carry out the planned plebiscite.

The Treaty of Saint-Germain with the Republic of Austria, signed on 10 September 1919, should have determined the Austrian-Yugoslav border. It ascertained that some small parts of Carinthia—i.e. the Meža Valley with the town of Dravograd and the Jezersko municipal area—should be incorporated into the new Kingdom of Serbs, Croats and Slovenes, while the fate of wider southeastern Carinthia area down to the Klagenfurt Basin was to be determined by a plebiscite.

The outcome of the plebiscite held on 10 October 1920, was 22,025 votes (59.1% of the total cast) in favor of adhesion to Austria and 15,279 (40.9%) in favor of annexation by the Kingdom of the Serbs, Croats, and Slovenes. Assuming that the whole German-speaking minority had voted for Austria, also every second Carinthian Slovene had decided to remain with the Republic. While a majority in the remote Alpine villages on the slopes of the Karawanks voted for Yugoslavia, the inhabitants of the densely settled Klagenfurt Basin were motivated by their evolved social and cultural, not least economic ties to the central Carinthian region.

The region was placed under Austrian administration on 18 November 1920 and declared part of the sovereign Austrian Republic on November 22. Up to today, October 10 is a public holiday in the State of Carinthia.

The plebiscite ultimately determined the border between Austria and the Kingdom of Serbs, Croats, and Slovenes. The border remained unchanged after World War II, even as the Kingdom of Yugoslavia gave way to Josip Broz Tito's Socialist Federal Republic of Yugoslavia, though at the end of the war Yugoslav Partisans again briefly occupied the area, including the capital city of Klagenfurt. Since the disintegration of Yugoslavia, the border separates Austria and Slovenia.
