Oldřich II of Rosenberg
Oldřich of Rosenberg (Rožmberk in Czech) was an important Czech nobleman, one of the leaders of the Catholic lords in Bohemia. His efforts increased the power and wealth of the House of Rosenberg, as he was able to take advantage of the weakening of the royal power during the Hussite wars, but he did not hesitate to use dishonest methods to expand his possessions, such as forging royal documents. He also began to promote the fictitious origins of the House of Rosenberg and the kinship with the Roman Orsini
