Hornolužické církevní instituce ve světle ustanovení krále Jana. Příspěvek k církevní politice Jana Lucemburského ve vedlejších zemích České koruny

The issue of the ecclesiastical history of the secondary lands of the Bohemian Crown continues to offer a number of topics for possible research. One of them is the relationship of King John of Luxembourg to the ecclesiastical institutions in Upper Lusatia, which he gradually brought into his immediate possession. He was thus able to fully develop his donating activities there. The aim of this paper is, based on sources of a diplomatic nature, to analyse and interpret the monarch’s policy towards the various ecclesiastical institutions in the region.
