The aim of the study is to present the potential of the surviving register of revenue and expenditure of the King of Hungary from 1494–1495 in relation to research on the personal composition of the royal court of Hungary and Bohemia. At the same time, emphasis was placed on the circle of persons from outside the Kingdom of Hungary. Analysis of the account material shows that after 1490, a group of people from the Czech Lands formed a group at the court in Buda that could not be overlooked. If we add to them identified courtiers of Polish – Lithuanian origin or with roots in the German regions of the Holy Roman Empire, they make up more than 60% of the people of noble origin, who gave colour to the court of King Vladislav Jagiello in Buda. A detailed prosopographical analysis of Vladislav’s court in the period 1490–1516 is still lacking. However, the partial analysis of the situation in in the mid 1490s shows that it was not just the Hungarian court with a not very important Bohemian appendix, but an institution fully representing both the Hungarian and Bohemian parts of Vladislav’s realms.
