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.
German revolutions of 1848–49
In 1848, Austria was the predominant German state. It was considered the successor to the Holy Roman Empire, which had been dissolved by Napoleon in 1806, and was not resurrected by the Congress of Vienna in 1815. German Austrian chancellor Klemens von Metternich had dominated Austrian politics from 1815 until 1848.
On March 13, 1848 university students mounted a large street demonstration in Vienna, and it was covered by the press across the German-speaking states. Following the important, but relatively minor, demonstrations against Lola Montez in Bavaria on February 9, 1848 (see below), the first major revolt of 1848 in German lands occurred in Vienna on March 13, 1848. The demonstrating students in Vienna had been restive and were encouraged by a sermon of Anton Füster, a liberal priest, on Sunday, March 12, 1848 in their university chapel. The student demonstrators demanded a constitution and a constituent assembly elected by universal male suffrage.
