Herzogtum Schweidnitz-Jauer
In 1096 Duke Bretislaus II of Bohemia captured and devastated the fortress, nevertheless in 1137 it returned to Poland. The following year, due to the fragmentation of Poland, Bardo became part of the Polish Duchy of Silesia. From 1278 it belonged to the Duchy of Jawor under the Piast duke Bolko I the Strict, from 1321 to the Duchy of Ziębice under Duke Bolko II. With Ziębice, Bardo was vassalized by the Kingdom of Bohemia in 1336, however, it remained under rule of local Polish dukes of the Piast dynasty until 1428.
