Jagiellonian dynasty
In 1382 and 1384, congresses of Polish nobility were held in Radomsko, during which Princess Jadwiga of Poland was chosen as Queen of Poland as the country's first female monarch. It was probably Radomsko where an agreement was concluded under which the future king of Poland Władysław II Jagiełło married Jadwiga, hence founding the Jagiellonian dynasty. Nowadays, Queen Jadwiga is considered the patron saint of Radomsko. The town developed under the patronage of the Jagiellonian dynasty, and was granted important trade and tax privileges by Kings Władysław II Jagiełło in 1427 and Sigismund II Augustus in 1549 and 1552.
