After the disintegration of the Austro-Hungarian Empire (following the First World War), the state of Austria — largely comprising the German-speaking parts of the former empire — became constituted as a parliamentary democracy. Two major factions dominated politics in the new nation: socialists (represented politically by the Social Democratic Workers' Party) and conservatives (politically represented by the Christian Social Party). The socialists found their strongholds in the working class districts of the cities, while the conservatives could build on the support of the rural population and of most of the upper classes.
