Brandenburg is one of the sixteen states of Germany. It lies in the east of the country and is one of the new states that were re-created in 1990 upon the reunification of the former West Germany and East Germany. The capital is Potsdam. Brandenburg surrounds but does not include the national capital Berlin.Historically, Brandenburg was an independent state, the Margraviate of Brandenburg, which grew to become the core of independent Prussia and later the German state of Prussia. About half of historic Brandenburg was annexed by Poland following the establishment of the new Oder-Neisse border in 1945 by the Allies.
The state of Brandenburg was named after the town of Brandenburg an der Havel.read full wikipedia reference about Brandenburg
