After the devastations during the 1241 Mongol invasion of Europe, the Olomouc bishop Bruno von Schauenburg had the area redeveloped by German craftspeopleand tradesmen descending from Schaumburg Land in the course of the "Ostsiedlung". In 1422 Hussite forces under Sigismund Korybut laid siege to the town, which upon the accession of the Hussite king George of Poděbrady in 1458 became a centre of the new confession until it fell to his rival Matthias Corvinus in 1479.
