Zgierz
Zgierz is an old town in the historic land of Łęczyca. Its first known mention records a meeting here in 1231 between the Piast dukes Władysław Odonic and Konrad of Masovia. The town acquired municipal rights before 1288, and King Władysław Jagiełło renewed them in 1420. Later kings sought to encourage its prosperity: John Albert granted a ten-year exemption from taxes in 1494, and Alexander Jagiellon established three annual fairs in 1504. Zgierz remained a royal town of the Polish Crown.
