Duchy of Münsterberg
A few weeks after Hynek's death, his son William — probably due to a preliminary contract concluded by Hynek — sold the possessions that had belonged to the Častolovice family, including the Lordship of Hummel, the lien of Kłodzko and the city of Ząbkowice Śląskie to George of Poděbrady, who would later be elected King of Bohemia and who already owned the adjacent Lordship of Náchod. This allowed George to extend his family's possessions in Eastern Bohemia. In 1456, he purchased the Duchy of Münsterberg from Ernest of Opava, thereby increasing his influence in Silesia. In 1459, George raised the Lordship of Kłodzko to a County, known in German as the County of Glatz.
