The First World War marked the end of the “long nineteenth century”. The monarchic empires were replaced by new political players. The Austro-Hungarian Monarchy disintegrated into separate nation states. The Republic of German Austria was proclaimed in November 1918, and Austria was established as a federal state in October 1920. The years after the war were highly agitated – in a conflicting atmosphere of revolution and defeat, and political, economic, social and cultural achievements and setbacks.
