What was decided at the Potsdam Conference after World War 2?

At the Potsdam Conference in July-August 1945, Allied leaders—U.S. President Harry S. Truman, British Prime Minister Winston Churchill (and later Clement Attlee), and Soviet Premier Joseph Stalin—discussed the post-war order in Europe. They agreed on the principles for the administration of Germany, including its demilitarization, denazification, and division into four occupation zones. The conference also addressed issues related to reparations, territorial adjustments, and the fate of Eastern Europe, setting the stage for the Cold War tensions that would follow.
