Silesia Province

The Province of Silesia 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, then became part of the German Empire in 1871. In 1919, as part of the Free State of Prussia within Weimar Germany, Silesia was divided into the provinces of Upper Silesia and Lower Silesia. Silesia was reunified briefly from 1 April 1938 to 27 January 1941 as a province of Nazi Germany before being divided back into Upper Silesia and Lower Silesia. Breslau (present-day Wrocław, Poland) was the provincial capital. Geography The territory on both sides of the Oder river formed the southeastern part of the Prussian kingdom. It comprised the bulk of the former Bohemian crown land of Upper and Lower Silesia as well as the adjacent County of Kladsko, which the Prussian King Frederick the Great had all conquered from the Austrian Habsburg monarchy under Empress Maria Theresa in the 18th century Silesian Wars. It furthermore included the northeastern part of Upper Lusatia around Görlitz and Lauban, ceded to Prussia by the Kingdom of Saxony according to the resolutions of the Vienna Congress in 1815.
