マイセン辺境伯
John II is first mentioned in a document of 1427, when he and his father sold a piece of land to the abbess of the monastery Doubravník, which had been founded by Štěpán of Medlov, a predecessor of the Pernstein family. In the same year, his father gave him the right to manage his own assets. In 1429, he participated in the Hussite invasion of the Margraviate of Meissen. Meissen was looted and pillaged.
