From 1373 the New March was part of the Lands of the Bohemian (Czech) Crown under the House of Luxembourg. The decay of the region continued: held by Jobst of Moravia since 1388, it was pawned by his cousin Sigismund (the later Holy Roman Emperor) to the Teutonic Knights in 1402, despite an agreement with Poland, based on which Poland was to buy and re-incorporate the territory. The Teutonic Knights also neglected the region, which furthermore was devastated by Hussite forces in 1433. In 1454 the Knights sold the New March to the Hohenzollern elector Frederick II of Brandenburg, in order to raise funds for war with Poland. From that time on, the Hohenzollerns retained the region; the red eagle of the town's coat of arms was taken from the coat of arms of Brandenburg.
