Reichsgau Wartheland
Rychtal lost town privileges in 1934. In the course of the 1939 Invasion of Poland, it was again occupied by Nazi Germany as part of the "Reichsgau Wartheland", attended with persecutions of the Polish speaking inhabitants. The area was overrun by the Red Army in the course of the Vistula–Oder Offensive in January 1945 and restored to the Republic of Poland.
