Historical Background
Silesia is a historical region in Central Europe. Historical territories of Silesia include:
 * Silesia, split between Poland, Czech Republic and Germany
 * Lower Silesia, split between Poland and Germany
 * Upper Silesia, split between Poland and the Czech Republic
 * Czech Silesia (sometimes Moravian Silesia), in the Czech Republic
 * Austrian Silesia, in the former Austrian Empire and Kingdom of Bohemia
 * Cieszyn Silesia or Těšín Silesia, split between Poland and the Czech Republic

 * The Prussian Province of Silesia (German: Provinz Schlesien) was a province of Prussia from 1815 to 1919.
 * The Silesia region was part of the Prussian realm since 1740 and established as an official province in 1815. It became part of the German Empire in 1871. This is the region featured in this article.


 * In 1919, as part of the Free State of Prussia within the Weimar Republic, Silesia was divided into the provinces of Upper Silesia and Lower Silesia. Silesia was reunified briefly from 1938 to 1941 as a province before being divided back into Upper Silesia and Lower Silesia.


 * Upon the implementation of the Oder-Neisse line according to the 1945 Potsdam Agreement, most of the Prussian Silesia Province became part of Poland, incorporated into the Lubusz, Lower Silesian, Opole and Silesian Voivodeships.
