Posen-West Prussia
After World War I, the economic situation deteriorated dramatically as the loss of the province of West Prussia meant that the town was now located on the border with Poland. It became part of the newly established Prussian province of Posen-West Prussia. In 1925, Preußisch Friedland had 3,830 inhabitants, among whom were 2,796 Protestants, 893 Catholics and 118 Jews. In 1938, the province of Posen-West Prussia was dissolved and Preußisch Friedland became part of the Province of Pomerania on October 1, 1938.
