The reign of Alexander I Jagiellonczyk (1501-1506) and Sigismund I the Old (1506-1548) was a period of fierce political struggle of the nobility with the nobility and the king to build a system of noble democracy. Alexander tried to block the aristocratic movement, but to no avail. The privilege he issued in 1501, which gave power to the Senate, was soon cancelled. It was replaced by a resolution of the Sejm, which was quite important for the Polish system, called Nihil novi, which decided that nothing new could be introduced from now on without the joint consent of the Members of the nobility, the Senate and the King. The nobility already had in their ranks at that time more and more numerous, well-educated representatives, such as Jan Łaski - Chancellor since 1503, and in the years 1510-1531 the Archbishop of Gniezno. Jan Grace represented the idea of a strong but not absolute state with codified law, good administration and a compact territorial structure. In 1506 he developed and announced a set of Polish laws called "The Statute of Grace". This document contained a list of all statutes and privileges in force in the Kingdom of Poland, which made it possible to unify the legal system, led to the centralisation of the state and, above all, to the dissemination of knowledge of the law among the nobility. Interestingly, the Łaski Statute was a fundamental source of law until the partitions. In the 17th century it was seized by the Swedes during the war, together with other Polish cultural assets. The coin's reverse presents an image of a fragment of woodcut depicting King Alexander Jagiellon sitting on the throne and Chancellor Jan Łaski. On the obverse of the coin there is an image of an eagle established as the national emblem of the Republic of Poland and an image of a book.
