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).
Austrians
On October 21, the German members of the Austrian parliament, elected in 1911, met in Vienna to found the Provisional National Assembly of German Austria ("Provisorische Nationalversammlung für Deutschösterreich"). On October 30, 1918 they installed the first German Austrian government, leaving the question "monarchy or republic" open. (German nationalists and social democrats favoured the republic, the Christian Socialists wanted to keep the monarchy.) This government in the first days of November took over the duties of the last imperial-royal government in a peaceful way. Initially the new state adopted the name "German Austria", reflecting the republic being the German part of the old Austria and showing the popular desire to unite with the new German republic. On November 12, 1918, the provisional national assembly voted for the republic and for unification with Germany with a large majority.
