This article presents court accounts as a source for research on the structure of royal court personnel in late medieval Poland. It addresses issues related to the organisation of this state institution and the shape and functioning of the Polish royal court during the reign of Casimir IV Jagiellon (1447–1492) and John Albert (1492–1501). The few surviving account books contain payroll lists for people who served at the court and were part of the court household. The registers of John Albert’s horse courtiers are particularly valuable sources for research on the Polish royal court.
