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).
Constituent National Assembly (Austria)
The Constituent National Assembly (), elected on 16 February 1919, was the first parliament in Austria's history to be elected by women and men in free and equal elections. On 4 March 1919 it replaced the Provisional National Assembly based on the 1911 Imperial Council elections. The National Assembly adopted the Habsburg Act, ratified the Treaty of Saint-Germain, which sealed the collapse of Cisleithania and demanded Austria's independence from Germany. In its last meeting on 1 October 1920, the assembly created the until-now lasting Constitution of Austria.
