With the issuance of the Berlin Declaration on 5 June 1945 and later creation of the Allied Control Council , the four Allied powers assumed temporary governance of Germany . At the Potsdam Conference in August 1945 , the Allies arranged for the Allied occupation and denazification of the country . Germany was split into four zones , each occupied by one of the Allied powers , who drew reparations from their zone . Since most of the industrial areas were in the western zones , the Soviet Union was transferred additional reparations . The Allied Control Council abolished Prussia on 20 May 1947 . Aid to Germany began arriving from the United States under the Marshall Plan in 1948 . The occupation lasted until 1949 , when the countries of East Germany and West Germany were created . In 1970 , Germany finalised her border with Poland by signing the Treaty of Warsaw . Germany remained divided until 1990 , when the Allies renounced all claims to German territory with the Treaty on the Final Settlement with Respect to Germany , under which Germany also renounced claims to territories lost during World War II
