European Advisory Commission The formation of the European Advisory Commission ( EAC ) was agreed on at the Moscow Conference on October 30 , 1943 between the foreign ministers of the United Kingdom , Anthony Eden , the United States , Cordell Hull , and the Soviet Union , Vyacheslav Molotov , and confirmed at the Tehran Conference in November . In anticipation of the defeat of Nazi Germany and its allies this commission was to study the postwar political problems in Europe and make recommendation to the three governments , including the surrender of the European enemy states and the machinery of its fulfillment . After the EAC completed its task it was dissolved at the Potsdam Conference in August 1945 . 1944 . The EAC had its seat in London at Lancaster House and started its work on January 14 , 1944 . William Strang was the British delegate , while on the American and Soviet side the respective ambassadors were the delegates , John G . Winant and Feodor T Gousev . The American military advisor was Cornelius Wickersham . George F . Kennan was a member of the American delegation in 1944 . At the Tehran Conference it was decided to hand over a large portion of German territory to Poland with the Oder – Neisse line as the eastern border of post - war Germany , and discussion about a possible partition of Germany were initiated by Roosevelt . Based on these premises , the EAC worked out the following recommendations during 1944 : 1945 . The work of the EAC was discussed at the Yalta Conference in 1945 where a major modification was approved as France received a seat on the ACC , and a future occupation zone in Germany was carved out from territory assigned to Great Britain and the United States . In addition , France received a future occupation zone in western Austria . On June 5 , 1945 the European Advisory Commission assumed briefly full control over Germany . Members included General Dwight Eisenhower for the US , Field Marshal Sir Bernard Montgomery for Britain , and Marshal Georgy Zhukov for the Soviet Union . The commission delimited German territory to its territory of December 31 , 1937 minus territory handed over to Poland and the Soviet Union , divided Germany into four zones of occupation under American , British , French , and Soviet military administration and separately divided Berlin into four sectors . The Commission ceased to exist after the Potsdam Conference , and the ACC was nominally the highest power in Germany , while in reality , each occupied zone was ruled by the respective occupying power Aftermath . The recommendations of the EAC shaped the development of postwar Europe . While it was by no means obvious at the Potsdam Conference that Germany would be partitioned into two states , the recommendations of the EAC allowed each occupying power full control over its occupied zone and deprived the ACC of an overruling influence . The subsequent Cold War thus was reflected in the partition of Germany as each occupying force could develop its zone on its own . The EAC failed to be specific about length and terms of occupation and different zones underwent different occupation experiences . The Soviet - occupied zone suffered disproportionally from war reparations while the Western Zone benefited from stimulatory economic impacts such as the Marshall Plan . Legally , the EAC ceased to function following the establishment of the Council of Foreign Ministers at the Potsdam Conference . References . Smyser WR : From Yalta to Berlin . St .
