In short
From July to August 1945, the leaders of the Soviet Union, United States, and United Kingdom met in Potsdam, Germany to decide how to reshape Europe after World War II's end. The conference produced agreements on German reparations, Soviet entry into the war against Japan, and the territorial map of postwar Europe-decisions that would lock in place the geopolitical divisions of the Cold War.
How it unfolded.
The five-minute version
What actually happened.
The Potsdam Conference was held at Potsdam in the Soviet occupation zone from 17 July to 2 August 1945, to allow the three leading Allies to plan the postwar peace, while avoiding the mistakes of the Paris Peace Conference of 1919. The participants were the Soviet Union, the United Kingdom, and the United States. They were represented respectively by General Secretary Joseph Stalin, prime ministers Winston Churchill and Clement Attlee, and President Harry S. Truman. They gathered to decide how to administer Germany, which had agreed to an unconditional surrender nine weeks earlier. The goals of the conference also included establishing the postwar order, solving issues on the peace treaty, and countering the effects of the war.

Same week, elsewhere
July 1945 marked shift from war relief to Cold War anxiety. Americans tested atomic bomb at Trinity (July 16, one day before conference began); Stalin learned of it during talks. Europe's future hung on three men in Potsdam as cameras captured images of the 'Big Three' for global audiences. Radio broadcasts brought conference updates worldwide, but full implications-Soviet domination of Eastern Europe, partition of Germany, nuclear age-wouldn't crystallize for months.
