The Gau March of Brandenburg (German: Mark Brandenburg) was formed in March 1933 initially under the name Gau Kurmark in Nazi Germany as a district within the Free State of Prussia. In January 1939, Kurmark was renamed March of Brandenburg. The Gau was dissolved in 1945, following Allied Soviet occupation of the area and Germany's formal surrender. After the war, the territory of the former Gau became part of the state of Brandenburg in East Germany except for areas beyond the Oder-Neisse line, which were given to the People's Republic of Poland. Most of its territory is now divided between Germany's State of Brandenburg and Poland's Lubusz Voivodeship.
