The Allied Control Council (ACC) or Allied Control Authority, also referred to as the Four Powers, was the governing body of the Allied occupation zones in Germany (1945–1949/1991) and Austria (1945–1955) following the end of World War II in Europe. Its members were the Soviet Union, the United Kingdom, the United States, and France. Following the defeat of the Nazis, Germany and Austria were occupied as two different areas, both by the same four Allies. Both were later divided into four zones by the 1 August 1945 Potsdam Agreement. The organisation was based in Schöneberg, West Berlin.
