The presented study is devoted to the phenomenon of the counterfeiting activity of Oldřich II of Rožmberk (Rosenberg, 1403-1462), particularly newly discovered forgeries and their interpretations. The motivation to create the forgeries was not ony legitimation of the holding of unjustly seized royal properties, but also the creation of the "image" of a fearless warrior against the Hussite opposition. The author combines diplomatic and historical methods to understand the background of creation of the three groups of forgeries related to the royal castle Zvíkov, the ecclesiastical goods of Svéráz and Zátoň and the trial with the nobleman Jan Smil of Křemže., Přemysl Bar., and Obsahue prameny a odkazy pod čarou
The study introduces the figure of Jan Železný - the bishop of Litomyšl (1388-1418) and Olomouc (1416/18-1430), administrator of the Prague diocese (1421-1430) and Cardinal Priest of the Title of St Cyriac (1426-1430), who is one of the most famous Bohemian opponents of Master Jan Hus and the Bohemian Reformation. Emphasis is placed on following the relationship of Jan Železný to King of Hungary, later of the Romans and Bohemia, Sigismund. This relationship began deep in the reign of Wenceslas IV, when Jan Železný was among the noble opposition to Wenceslas and therefore cooperated with the King of Hungary, but it acquired a new intensity in the context of the death of Jan Hus and particularly in connection with the wars of Sigismund against the Hussites. In the first half of the 1420s, Jan Železný was an important link in Sigismund´s military coalition, but in the second half of the 1420s he had to go into exile at Sigismund´s court and following the intentions of Pope Martin V he attempted to stop the new course of Sigismund´s Hussite policy., Petr Elbel., and Obsahuje seznam pramenů a odkazy pod čarou
