The new state managed to block two land claims by its neighbours. The first was the south-eastern part of Carinthia, which was inhabited partly by Slovenians. It was prevented from being taken over by the new SHS-state through a Carinthian plebiscite on October 10, 1920, in which the majority of population chose to remain with Austria. The second prevented land-claim was Hungary's claim to Burgenland, which, under the name "Western Hungary", had been part of the Hungarian kingdom since 907. It was inhabited mostly by a German-speaking population, but had also Croat- and Hungarian-speaking minorities. Through the Treaty of St. Germain it became part of the Austrian Republic in 1921. However, after a plebiscite which was disputed by Austria, the provincial capital city of Sopron (German Ödenburg) remained in Hungary.
