History
Following the joint German-Soviet invasion of Poland, which started World War II in September 1939, the town was occupied by Germany until 1945. In 1943, the occupiers renamed it Treustädt in attempt to erase traces of Polish origin.

From 1975 to 1998, it was administratively located in the Kalisz Voivodeship.
