Silesia (Polish: Śląsk, Czech: Slezsko) is a historical landscape, which today is mainly located in the extreme southwest of Poland, but in parts also on the territory of Germany and the Czech Republic. By far the most significant river is the Oder. To the south, Silesia is bordered mainly by the Sudeten and Beskid mountain ranges. Today, almost 8 million people live in Silesia. The largest cities in the region are Wrocław, Opole and Katowice. Before 1945, most of the region was part of Prussia for two hundred years, and before the Silesian Wars (from 1740) it was part of the Habsburg Empire for almost as many years. Silesia is classified into Upper and Lower Silesia.
Upper Lusatia, formerly a margraviate taking its name from neighboring Lower Lusatia, is now a cross-border historical landscape. While most of it belongs to the state of Saxony and a very small part to Brandenburg, about one third, namely the area between the Lusatian Neisse and the Queis (Kwisa in Polish), is Polish. Important cities on the German side are, for example, Bautzen, Zittau and Görlitz, and on the Polish side Zgorzelec, Lubań (Lauban) and Bogatynia (Reichenau).
