History of Austria
Austria was dominated by the House of Habsburg and House of Habsburg-Lorraine ("Haus Österreich") from 1273 to 1918. In 1808, when Emperor Francis II of Austria dissolved the Holy Roman Empire, Austria became the Austrian Empire, and was also part of the German Confederation until the Austro-Prussian War of 1866. In 1867, Austria formed a dual monarchy with Hungary: the Austro-Hungarian Empire (1867–1918). When this empire collapsed after the end of World War I in 1918, Austria was reduced to the main, mostly German-speaking areas of the empire (its current frontiers), and adopted the name The Republic of German-Austria. However the union and name were forbidden by the Allies at the Treaty of Versailles. This led to the creation of the First Austrian Republic (1918-1933).
Government of Austria
After the dissolution of the Austro-Hungarian Monarchy, on 30 October 1918 the provisional national assembly of German Austria elected a State Council ("Staatsrat") executive, which itself appointed a state government with the Social Democratic politician Karl Renner as head of the State Chancellery. The Renner ministry was composed of representatives of the three main political parties—Social Democrats, the Christian Social Party (CS) and German Nationalists (Greater Germans)—according to the "Proporz" doctrine. As acting executive body it remained in office until the Constitutional Assembly of the Austrian First Republic on 15 March 1919 elected Renner's second cabinet, a coalition government of Social Democratic and Christian Social ministers.
