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
After Austria was excluded from Germany in 1866, the following year Austria joined Hungary as a dual empire known as the Austro-Hungarian Empire. A further major change resulted from a reorganisation of the Austrian Empire in 1867 into a dual monarchy, acknowledging the Kingdom of Hungary as an independent state bound to the remaining part of the empire, as well independent, by a personal and real union, the Emperor of Austria being the Apostolic King of Hungary (with both titles on the same level). The Austrian half, a patchwork of crown-lands, broadly coterminous with the modern-day Austria, the Czech Republic, Slovenia, and parts of Poland, Ukraine, Italy, and Croatia, was bound together by the common constitution of 1867, stating that all subjects now would carry "uniform Austrian citizenship" and have the same fundamental rights. These non-Hungarian lands were not officially called the Austrian Empire. Until 1915, they were officially called "the Kingdoms and States Represented in the Imperial Council" and politicians used the technical term Cisleithania (labelling the Hungarian lands as Transleithania). The general public called them Austria, and in 1915, the non-parliamentary Cisleithanian government decreed to use this term officially, too.
