The intended governing body of Germany was called the Allied Control Council, consisting of the commanders-in-chief in Germany of the United States, the United Kingdom, France and the Soviet Union; who exercised supreme authority in their respective zones, while supposedly acting in concert on questions affecting the whole country. In actuality however, the French consistently blocked any progress towards re-establishing all-German governing institutions; substantially in pursuit of French aspirations for a dismembered Germany, but also as a response to the exclusion of France from the Yalta and Potsdam conferences. Berlin, which lay in the Soviet (eastern) sector, was also divided into four sectors with the Western sectors later becoming West Berlin and the Soviet sector becoming East Berlin, capital of East Germany.
