In 1481, Radom became the residence of Prince Kazimierz, the son of King Jagiellon, who ruled the Grand Duchy of Lithuania. The young prince died of tuberculosis, and later became patron saint of both the city of Radom (since 1983), and the Roman Catholic Diocese of Radom (since 1992). During the reign of Alexander Jagiellon, the Nihil novi act was adopted by the Polish Sejm in a meeting at Radom Castle. Furthermore, at the same meeting, the first codification of law published in the Kingdom of Poland was accepted. Radom remained one of the most important urban centers of Sandomierz Voivodeship, the seat of a county, and of the Treasure Tribunal (1613-1764), which controlled taxation. Several kings visited the city, including Stephen Bathory and his wife Anna Jagiellon, Sigismund III Vasa, and August III Sas. In 1623 many residents died in an epidemic, and in 1628, half of Radom burned in a fire.
