The Potsdam Conference was the last in which the leaders of the three great powers - Churchill, Truman, and Stalin - took part. The West agreed to cede German territory east of the River Oder to Poland. To compensate the Soviet Union for its war effort, an agreement was concluded in which the USSR would be given pieces of German, Austrian, Bulgarian, Hungarian, Romanian, and Finnish territory.
Germany was partitioned into four spheres of influence: a Soviet sector, in the east; a British sector, in the north-west, a French sector, in the south-west; and, an American sector, in the south. Berlin, although situated entirely in the Soviet occupation sector, was removed from this jurisdiction, partitioned into four sectors following the pattern used in the rest of Germany, and placed under a quadripartite command.
