Province of the Sudetenland
The Province of the Sudetenland (German: Provinz Sudetenland) was established on 29 October 1918 by former members of the Cisleithanian Imperial Council, the governing legislature of the crumbling Austro-Hungarian Empire. It consisted of German-speaking parts of Moravia, Bohemia and Austrian Silesia, and was meant to become an integral part of the newly proclaimed Republic of German Austria. 
The province was originally established by the provisional government of so-called "German Moravia", which meant to represent German interests in Moravia. The provisional capital was declared as Troppau (Opava). This mimicked a similar provincial establishment in Bohemia,where Reichenberg (Liberec) became the capital.
Along with various other German-speaking parts, these provinces were intended to eventually integrate into Austria, on the basis of Woodrow Wilson’s Fourteen Points, which emphasized the right to self-determination of peoples. This would not come to pass, however. Both the provinces of German Bohemia and German Moravia were given to the newly proclaimed Czecho-Slovak Republic. Czechoslovak troops occupied the province by the beginning of 1919, and position of said province within Czechoslovakia was confirmed by the Treaty of Saint-Germain-en-Laye, which was signed 10 September 1919.
In 1919, about 646,800 ethnic Germans lived within the province, along with about 25,000 ethnic Czechs.
