With the war in Europe over, the Allied powers had to turn to the difficult business of governing Germany and the other occupied territories. It was a huge task: to restart a functioning economy for an entire continent, to restore systems of law and government, to bind up the wounds of war. On June 5, 1945, the US, UK, USSR, and France jointly assumed "supreme authority" over German territory. The Third Reich was now dead, and Germany officially passed under the control of the victorious Allies.
