Coat of arms

The Duchy of Bernstadt (German: Herzogtum Bernstadt, Polish: Księstwo bierutowskie, Czech: Bernštatské knížectví) was a Silesian duchy centred on the city of Bernstadt (present-day Bierutów) in Lower Silesia (now in Poland) and formed by separation from the Duchy of Oels (Oleśnica). It was first ruled by the Silesian Piasts dynasty, until its extinction in 1492. In 1495 it and the Duchy of Oels passed to the Dukes of Münsterberg, who came from the House of Poděbrady. In 1647 the Duchy of Bernstadt passed by marriage to the Dukes of Württemberg.

That the Duchy of Bernstadt at first belonged to the Silesian Duchy of Oels which had since 1329 been a fief of the Bohemian Crown. Upon the death of Duke Konrad III the Old in 1412, it was split off for his first-born son Conrad IV the Elder, who at first also ruled over the other Oels territories as a regent for his minor brothers until they formally divided their heritage in 1416. The next year, Konrad IV succeeded Wenceslaus II of Liegnitz as Prince-Bishop of Breslau. When he died in 1447, Bernstadt fell back to his younger brother Duke Konrad VII the White of Oels.
