The Final Settlement Treaty ended Berlin's special status as a separate area under Four Power control. Under the terms of the treaty between West and East Germany, Berlin became the capital of a unified Germany. The Bundestag voted in June 1991 to make Berlin the seat of government. The Government of Germany asked the Allies to maintain a military presence in Berlin until the complete withdrawal of the Western Group of Forces (ex-Soviet) from the territory of the former East Germany. The Russian withdrawal was completed 31 August 1994. Ceremonies were held on 8 September 1994, to mark the final departure of Western Allied troops from Berlin.
