Zwei-plus-Vier-Vertrag
Treaty on the Final Settlement with Respect to Germany: Under the terms of this peace treaty, the Four Powers renounced all rights they formerly held in Germany, including Berlin. As a result, following the acts of official German reunification achieved on 3 October 1990 and which itself was enabled by the Treaty, Germany became fully sovereign on 15 March 1991. Under the terms of the Treaty, the Allies were allowed to keep troops in Berlin until the end of 1994 (articles 4 and 5). In accordance with the Treaty, occupying troops were withdrawn by that deadline.
