Hieronim Łaski i imieninowe przyjęcie na zamku w Csabie? Stosunki polsko-węgierskie w komitacie Békés w XV–XVI wieku

Békés County lies far from Poland, yet several connections existed between these regions in the fifteenth and sixteenth centuries. In January 1444 King Władysław Warneńczyk of the Jagiełło dynasty granted an estate to a nobleman from Békés County. Hungarians from the southern part of the Great Plain studied in Poland, and Polish warriors appeared in the region of the castle of Gyula in 1529. It is also possible that Hieronym Łaski, the well-known Polish politician in the service of King John Szapolyai, was invited to the little castle of Csaba – present-day Békéscsaba. A letter issued by King Ferdinand in 1531 provides additional insight into the negotiation between King John and King Ferdinand, conducted with the mediation of King Sigismund of Poland in that year. The original of this letter is preserved in Kassa, while a contemporary copy survives in Békéscsaba. King Sigismund’s intercession in the matter of Gyula is a further chapter in the Polish–Brandenburg–Hungarian relations.
