other areas of the Empire were now perceived to be on the "victor" side, simply because they had renounced the Empire at the end of the war. Austria never did have to pay reparations because allied commissions determined that the country could not afford to pay. However, the Treaty of Saint Germain also confirmed Austria's loss of significant German-speaking territories, in particular the southern part of the County of Tyrol (now South Tyrol) to Italy and the German-speaking areas within Bohemia and Moravia to Czechoslovakia. In compensation (as it were) it was to be awarded most of the German-speaking part of Hungary in the Treaty of Trianon concluded between the Allies and that country; this was constituted the new federal state of Burgenland. End of grand coalition and new constitution (1920–1933) The grand coalition was dissolved on 10 June 1920, being replaced by a CS- SDAPÖ coalition under Michael Mayr as Chancellor (7 July 1920 – 21 June 1921), necessitating new elections which were held on 17 October, for what now became the National Council (Nationalrat), under the new constitution of 1 October. This resulted in the Christian Social party now emerging as the strongest party, with 42% of the votes and subsequently forming Mayr's second government on 22 October as a CS minority government (with the support of the GDVP) without the Social Democrats. The CS were to continue in power until the end of the first republic, in various combinations of coalitions with the GDVP and Landbund (founded 1919). The borders continued to be somewhat uncertain because of plebiscites in the tradition of Woodrow Wilson. Plebiscites in the regions of Tyrol and Salzburg between 1919 and 1921 (Tyrol 24 April 1921, Salzburg 29 May 1921) yielded majorities of 98% and 99% in favour of unification with Germany, fearing that "rump" Austria was not economically viable. However such mergers were not possible under the treaty. On 20 October 1920, a plebiscite in part of the Austrian state of Carinthia was held in which the population chose to remain a part of Austria, rejecting the territorial claims of the Kingdom of Serbs, Croats and Slovenes to the state. Mostly German-speaking parts of western Hungary was awarded to Austria as the new state of Burgenland in 1921, with the exception of the city of Sopron and adjacent territories, whose population decided in a referendum (which is sometimes considered by Austrians to
