After the successful Polish Greater Poland uprising of 1806, Kargowa was regained by the Poles and became part of the short-lived Polish Duchy of Warsaw. In 1815 it was annexed by Prussia for the second time. After Poland regained independence, Kargowa was captured by Polish insurgents in 1919; however, the Treaty of Versailles granted the town to Germany.
During the final stages of World War II in 1945, a German-perpetrated death march of Jewish women from a just dissolved subcamp of the Gross-Rosen concentration camp in Sława passed through the town.[6] The town finally returned to Poland after the defeat of Nazi Germany in World War II in 1945.
