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).
Austria under National Socialism
On 12 February 1934 there was a violent confrontation in Linz with serious consequences. Members of a paramilitary group acting to assist the police wanted to enter a building belonging to the Social Democrats or a party member's home. They wanted to find any weapons belonging to the Social Democrat paramilitary which had by then been banned. Violence spread to the whole country and developed into civil war. The police and their paramilitary supporters together with the army won the confrontation by the 14 February. There were many arrests. Constitutional courts were abolished, trade unions and the Social Democrat Party were banned, and the death penalty was reintroduced. After political opposition had been suppressed the Austrian Republic was transformed into the Austrofacist "Ständestaat". The authoritarian "Maiverfassung" (May Constitution) was proclaimed on 1 May.
