I have been studying János Perényi’s career since 2009. In the essays I have published since
then I covered the outline of his career, his relation to royal power and to the magnates and his
position within the national council. In my papers which are about to be published I examined
the beginning of his political career, the history of his family’s possessions and the use of
their residence. Besides the conclusions of the literature, these studies are based mainly on
already published diplomas and on the sources I have collected. In my present paper I intend
to summarize the results of the sources collection I have carried out in the course of my stud
ies abroad and during my professional practices. Conducting a research in the archives of the
MNL OL and also in the archives of the free royal cities of Upper-Hungary I collected the
charters issued or confirmed by János Percnyi. I used the database of the MNL OL DL-DF as
the basis of my investigation. Since I was predominantly interested in the seals attached to the
charters, the inspection of the diplomas and letters kept abroad was inevitable. I photographed
all these seals or had them photographed.
As a result of my research I created a database which contains the charters issued or
confirmed by János Percnyi and also the seals attached to these charters. I publish these in
formation in a summarizing table at the end of this paper. My work could not have been com
pleted without listing thepolysigillic diplomas and were issued between 1439 and 1457. My
studies written about the building of this database together with the conclusions I have drawn
from it will be available to the public soon.
Based on the above mentioned database and also on my previous research I try to find
out whether the seal usage of Percnyi reflected his relation to national politics and the role he
played in it and his party affiliations. For my investigation I also use the results of the works
written on the functioning and seal usage of medieval judicial offices, the results of already
published itineraries and discourses on political history
