What was the purpose of the potsdam conference and who attended

The Potsdam Conference was attended by the "Big Three": Joseph Stalin of the Soviet Union, Winston Churchill of Great Britain, and Harry S. Truman of the United States. These leaders had a sense that the war would soon end and the Allies would be victors, so the whole purpose of this conference was to plan what would happen after World War II ended. They discussed issues such as the German economy, punishment for war criminals (especially Nazis), as well as land boundaries and reparations.
