Fall of Austria-Hungary

The collapse of the Habsburg monarchy at the end of the First World War. By October 1918 the constituent nationalities of Austria-Hungary were declaring independent states; on 11 November Emperor Karl I issued a proclamation renouncing participation in state affairs, though he never formally abdicated. The empire dissolved into the new Austria, Hungary, Czechoslovakia, Yugoslavia, and parts of Poland, Italy, and Romania — ending six centuries of Habsburg rule.
