Polish and Hungarian lords in the entourage of Władysław, King of Poland and Hungary 1440–1442

Based on the analysis of sources it can be stated that Polish presence near the king was constant and significant. The most significant officials temporarily supported the king, but did not accompany the ruler on his military campaigns. The king held Polish–Hungarian joint councils from as early as 1440. It is most probable that a significant part of the Poles took the Hungarian efforts of Władysław seriously, and many noble families saw great potential in a Hungarian service. In this paper we endeavored to call attention to the fact that a vast amount of Polish‑related genealogical data (seals, itinerary supplements) can be found from this era in the Hungarian and Austrian archives. We hope that this collection will provide assistance to many in their research.
