Historically Austrians were regarded as ethnic Germans and viewed themselves as such, although this national identity was challenged by Austrian nationalism in the decades after the end of World War I and even more so after World War II. Austria was part of the Holy Roman Empire of the German Nation until its ending in 1806 and had been part of the German Confederation, a loose association of 39 separate German-speaking countries, until the Austro-Prussian war in 1866, which resulted in the exclusion of Austria from the German Confederation and the creation of the North German Confederation led by Prussia. In 1871, Germany was founded as a nation-state, Austria was not a part of it. After World War I and the breakup of the Austrian monarchy, politicians of the new republic declared its name to be "Deutschösterreich" (Republic of German-Austria) and that it was part of the German Republic. A unification of the two countries was forbidden by the treaty of Saint-Germain-en-Laye as one of the conditions imposed by the victorious Allies of World War I upon the vanquished nation, to prevent the creation of a territorially extensive German state. After the events of World War II and Nazism, Austria as a country has made efforts to develop an Austrian national identity among its populace, and nowadays most do not consider themselves Germans. However, a minority of Austrians still consider themselves to be Germans and advocate for a "Greater Germany", arguing that the historic boundaries of the German people goes beyond the boundaries of modern-day countries, especially Austria and Germany.
