Regierungsbezirk Breslau, known colloquially as Middle Silesia (German: Mittelschlesien, Silesian: Strzodkowy Ślōnsk, Polish: Śląsk Środkowy) was a Regierungsbezirk, or government region, in the Prussian Province of Silesia and later Lower Silesia from 1813 to 1945. It comprised the eastern parts of the historic Lower Silesia region and the former County of Kladsko, both of which were conquered by Prussia in the First Silesian War in 1742.
