Duchy of Nysa
The golden mines in the Zlaté Hory area were first mentioned in a document from 1224. Zlaté Hory (under its old name "Cukmantl") was first mentioned in 1263. In the Middle Ages, it was disputed and changed owners several times between Czech dukes from the houses of Přemyslid and Podiebrad on one side, and Polish dukes from the Piast dynasty and bishops of Wrocław on the other. It was eventually purchased by the bishopric in the 1470s, and included within the ecclesiastical Duchy of Nysa, under suzerainty of the Bohemian (Czech) Crown. In 1850, the duchy was secularized and dissolved, and the town was incorporated directly to the Bohemian Crown, then under Austrian rule.
