The dissolution of the Habsburg Monarchy left an equally bitter legacy. The Austrian half of the Monarchy lost, in the north, the Czechs who joined their Slovak cousins from Hungary in a Czechoslovak Republic that contained, in the Sudetenland on its western frontier, a worrying minority of Germans. In the south they lost the Slovenes, who with their Croat cousins from Hungary linked their fortunes with the Serbs in a clumsily entitled ‘Kingdom of the Serbs, Croats and Slovenes’, later to be renamed Jugoslavia (south Slavia). They lost their Italian lands south of the Alps, including Trieste, their main port on the Adriatic; but the territories promised to Italy on the eastern shores of the Adriatic were now in the possession of the ‘liberated’ Jugoslavs, who themselves had claims on Trieste and its hinterland.
The Germanspeaking rump that was all that remained of Austria initially tried to join the new German republic to the north, but this was forbidden by the Allies. So Austria remained independent for a further twenty years until 1938, when an Anschluss was achieved to universal popular acclaim by one of her former citizens, Adolf Hitler. The Hungarians lost not only the Slovaks to the north and the Croats to the south, but the province of Transylvania in the east to a greatly enlarged Rumania, suffering an ugly little civil war in the process. The right-wing dictator who emerged from the mêlée, Admiral Horthy, refused to admit that the abdication of the Habsburgs had been valid at all and declared that he ruled merely as regent on their behalf. He continued to do so until he was himself overthrown at the end of the Second World War.
