Gorzów Wielkopolski was founded as a Slavic fortress in the 11th century. In 1257 it became a city under the control of the German margravate (county) of Brandenburg. Destroyed in the Thirty Years' War (1618-1648), the city was rebuilt and prospered in the 18th and 19th centuries. Known by the German name of Landsberg, the city remained under the control of Germany until the end of World War II in 1945, when postwar border agreements assigned the city to Poland. Population (1997 estimate) 125,300.
