It was a private village located in the Kalisz Voivodeship in the Greater Poland Province of the Polish Crown until the late 18th-century Partitions of Poland, when it was annexed by Prussia. Before 1945 it was part of Germany, however it remained a Polish center, and in the interbellum a Polish school existed in the village. After the German invasion of Poland, which started World War II, Poles were persecuted. The Germans arrested local Polish activists and the local Polish teacher Czesław Mikołajczyk, who were imprisoned and killed in the Flossenbürg and Sachsenhausen concentration camps.
