Namysłów
Namysłów was a Silesian Piast principality centred on the town on the Widawa. Around 1337 Casimir I of Cieszyn held it temporarily as dowry for his daughter Anna's marriage to Wenceslaus I of Legnica.
In 1342 Bolesław III of Legnica sold his rights to Poland's Casimir III, who used the castle as a residence. At Namysłów in 1348 Casimir renounced his Silesian claims in favour of Bohemia's Charles IV; the town passed to the Bohemian Crown in 1358. It passed to the Habsburgs in 1526 and Prussia in 1742.
