ENResearch on the administrative elites in the Kingdom of Poland has predominantly focused on analyzing the participation of individual people and families in these elites. This study presents findings on the system of land offices, their functioning during the Jagiellonian dynasty, and, consequently, the nomination policies of individual rulers, observed from a systemic perspective. The author highlights the key aspects of this policy, visible until the reign of Sigismund Augustus: the adoption of established hierarchies of land offices from the period of the fragmentation of the Kingdom, the elimination of the lowest-ranked offices in the land hierarchies, and, on the other hand, the creation of new hierarchies related to land judicature (judge, deputy judge, clerk) and the management of royal estates (district starosties). New voivodeships and offices with real competencies at that time were also established. The direction of this policy underwent significant transformation during the reign of the last Jagiellon. In seeking an understanding with the lesser nobility, the king aimed to gain their support by granting or creating new, previously unknown lower land offices in various territories.
