In 1402, with the death of the fourth archbishop of Prague Obram of Škvorec an almost fortyyear period was capped, during which the office of the archbishop of Prague was held exclusively by the members of two originally burgher families - the descendants of Jan of Kamenice and the Olbramovice family. The successor of the first archbishop of Prague Arnošt of Pardubice became Jan Očko, the son of a burgher and the court scribe of King John of Luxembourg Jan of Kamenice. His nephew Jan of Jenštejn was elected as the uncle's successor on the metropolitan throne, on which in the end even Očko's grand-nephew Olbram of Škvorec sat. It was not the first case when sons coming from burgher families held high ecclesiastical post. Using the example of the admirable careers of three burgher sons, we can attempt to observe the basic mechanisms of the social and economic rise of the urban elites under the Luxembourgs, which found its reflection also in their representation. The social and property rise also crated the essential prerequisite for their penetration among the court and ecclesiastical elite.
