Kladsko developed rapidly until the start of the Hussite Wars in the 15th century. The wars left the town depopulated by plagues, partially burnt, and demolished by several consecutive floods. In 1459 whole Kłodzko Land was elevated by Bohemian king George of Poděbrady to the status of county – thus the city became a seat of Count (for most of time ruler of Bohemia itself) and local Diet – but still remained integral part of Bohemia as "outer region" (), and was not counted as part of Silesia. In 1472, the Polish prince Vladislaus Jagiellon stayed in the city before his coronation as King of Bohemia in Prague.
