History

Łyśniewo was a royal village of the Kingdom of Poland, administratively located in the Mirachowo County in the Pomeranian Voivodeship. During the German occupation of Poland (World War II), in 1939, some Poles from Łyśniewo Sierakowickie were among the victims of a massacre committed by the Germans in nearby Kaliska as part of the genocidal Intelligenzaktion campaign. In 1944, the German police carried out expulsions of Poles, who were deported to the Potulice concentration camp, while their farms were handed over to German colonists as part of the Lebensraum policy.
