The Duchy of Prudnik (pl|Księstwo prudnickie, de|Herzogtum Prudnik, cs|Prudnícké knížectví) was one of the numerous duchies of Silesia ruled by the Silesian branch of the royal Polish Piast dynasty. Its capital was Prudnik in Upper Silesia.
The Duchy of Prudnik was separated from the Kingdom of Bohemia by Nicholas II in 1318.[1] [2] He ruled over the duchy until 1337,[3] when he was forced to give Prudnik to Bolesław the Elder. The duchy returned under Nicholas' rule in 1361 thanks to his marriage with Juta, the princess of Niemodlin and daughter of Bolesław.[4]
After the death of Euphemia of Masovia, widow of Vladislaus II of Opole by 1424, Bernard of Niemodlin and his brother Bolko IV of Opole inherited her dower lands, Głogówek, which at the end of that year was given to Bolko IV's son, Bolko V the Hussite.
In 1424, after Bolko V the Hussite became the independent ruler over Głogówek and Prudnik thanks to the resignation of both his father and uncle Bernard, forming the united Duchy of Głogówek and Prudnik.[5] [6]
