On February 16, 1919, an armistice ended the Polish-German fighting, and on June 28, 1919, with the signing of the Treaty of Versailles , the German government officially ceded the Jarotschin district to the newly founded Poland.
Of the population in 1890, 87% were Poles, 11% German and 2% Jews. The majority of the German residents left the district after 1919.

The district of Jarotschin in occupied Poland (1939–1945)
During the Second World War , the German occupation authorities formed the district of Jarotschin in the administrative district of Poznan , which included the former districts of Jarotschin and Pleschen . The annexation of the area by the German Reich on October 26, 1939 , as a unilateral act of violence, was ineffective under international law. Most of the Jewish population was murdered by the German occupation authorities. The German occupation ended with the invasion of the Red Army in January 1945.

During the German occupation in World War II , only Jarotschin in 1942 and Pleschen in 1943 received city rights according to the German municipal code of 1935; the other municipalities were grouped together in administrative districts .
During the German occupation, the place names valid in 1918 were initially adopted by an unpublished decree of December 29, 1939, but "wild" Germanizations by the local occupation authorities soon followed. On May 18, 1943, all places with a post or train station were given German names, mostly phonetic adjustments, translations or free inventions.
