This paper, focused on facts, tries to describe the main changes in Lower Lusatia and the operation of the land administration under the rule of the Jagiellons between 1490 and 1526. The study is based on detailed comparison of the situation in all Lands of the Czech Crown, namely in Bohemia, whereas special attention is paid to the description of the family background, family relationships and the career life of individual administrators. The paper also researches the reasons which led Czech Kings to the appointment of land administrators and tries to answer the question how much land administrators influenced events in Lower Lusatia. The Lower- Lusatian estates played an important role as well and both, land administrators and the Jagiellons, could repeatedly experience their increasing power during the monitored period.
