Silesia  is a region of Central Europe located mostly in Poland, with small parts in the Czech Republic and Germany. Its area is about 40,000 km2 (15,444 sq mi), and its population about 8,000,000. Silesia is located along the Oder River. It consists of Lower Silesia and Upper Silesia.

The region is rich in mineral and natural resources, and includes several important industrial areas. Silesia's largest city and historical capital is Wrocław. The biggest metropolitan area is the Upper Silesian metropolitan area, the centre of which is Katowice. Parts of the Czech city of Ostrava fall within the borders of Silesia.

Silesia's borders and national affiliation have changed over time, both when it was a hereditary possession of noble houses and after the rise of modern nation-states. The first known states to hold power there were probably those of Greater Moravia at the end of the 9th century and Bohemia early in the 10th century. In the 10th century, Silesia was incorporated into the early Polish state, and after its division in the 12th century became a Piast duchy. In the 14th century, it became a constituent part of the Bohemian Crown Lands under the Holy Roman Empire, which passed to the Austrian Habsburg Monarchy in 1526.

Most of Silesia was conquered by Prussia in 1742, later becoming part of the German Empire, the Weimar Republic, and Nazi Germany up to 1945. The varied history with changing aristocratic possessions resulted in an abundance of castles in Silesia, especially in the Jelenia Góra valley. After World War I, the easternmost part of this region, i.e. an eastern strip of Upper Silesia, was awarded to Poland by the Entente Powers after rebellions by Polish people and the Upper Silesian plebiscite. The remaining former Austrian parts of Silesia were partitioned to Czechoslovakia, and are today part of the Czech Republic. In 1945, after World War II, the bulk of Silesia was transferred to Polish jurisdiction by the Potsdam Agreement of the victorious Allied Powers and became part of Poland. The small Lusatian strip west of the Oder-Neisse line, which had belonged to Silesia since 1815, remained in Germany. Its centres are Görlitz and Bautzen.

Most inhabitants of Silesia today speak the national languages of their respective countries (Polish and Czech, both of which are Western Slavic languages, with some, albeit limited, mutual intelligibility). The population of Upper Silesia is native (with some immigrants from Poland who came in the 19th to 20th centuries), while Lower Silesia was settled by a German-speaking population before 1945. An ongoing debate exists whether Silesian speech should be considered a dialect of Polish or a separate language.[citation needed] Also, a Lower Silesian German dialect is used, although today it is almost extinct.[citation needed] It is used by expellees within Germany, as well as Germans who were left behind.
