Duchy of Münsterberg
King George's possessions were divided among his sons according to the inheritance plan in 1472. Henry the Elder received the County of Kladsko, the Silesian Duchy of Münsterberg, including Frankenstein and the East Bohemian dominions Náchod, Vízmburk Castle, Kunětice Mountain Castle and the lands of the now defunct monasteries of Opatovice and Sezemice that had been devastated in the Hussite Wars. King Vladislas confirmed on these possessions on 3 and 29 April 1472. After the emperor had confirmed the privileges for the vassalage of the county of Kladsko, he asked his subjects in Kladsko to paid homage to Duke Henry. The estates of the county paid homage to the new Duke at his castle in Kladsko.
