Austrians
Historically, Austrians were regarded as ethnic Germans and viewed themselves as such. Austria was part of the Holy Roman Empire and the German Confederation until the Austro-Prussian war in 1866 which resulted in Prussia expelling Austria from the Confederation. Thus, when Germany was founded as a nation-state in 1871, Austria was not a part of it. In 1867, Austria was reformed into the Austro-Hungarian Empire. After the collapse of the Austro-Hungarian Empire in 1918 at the end of World War I, Austria was reduced to a rump state and adopted and briefly used the name the Republic of German-Austria ("Republik Deutschösterreich") in an attempt for union with the Republic of Germany, but was forbidden due to the Treaty of Saint-Germain-en-Laye (1919). The First Austrian Republic was founded in 1919. The Third Reich annexed Austria with the "Anschluss" in 1938.
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.
