Since Lesser Poland was the most important province of the country, several important events took place on its territory. In 1364, Casimir the Great called the Congress of Kraków, and in 1401, the Union of Vilnius and Radom was signed. In 1505 in Radom, the Sejm adopted the Nihil novi title, which forbade the King to issue laws without the consent of the nobility. In the same year, also in the same city, Polish law was codified in the Łaski's Statute, and the Crown Tribunal (the highest appeal court in the Crown of the Polish Kingdom) held its sessions in Lublin. In 1525, the Treaty of Kraków was signed, ending the Polish–Teutonic War. Lesser Poland also is home to the oldest Polish university – the Jagiellonian University, founded in 1364 by Casimir the Great, and several outstanding figures of early Polish culture were born here, such as Jan Kochanowski, Mikołaj Rej, Jan z Lublina, Mikołaj Gomółka, Maciej Miechowita, Marcin Kromer, Łukasz Górnicki, and Mikołaj Radomski.
