Allied Conferences: Yalta and Potsdam
How the Allied leaders divided the post-war world at Yalta and Potsdam — and planted the seeds of the Cold War.
Dividing the Post-War World
The Yalta Conference (February 1945) brought together Roosevelt, Churchill, and Stalin to plan the post-war order while Germany's defeat was imminent but not yet complete. Key agreements included: Germany's division into occupation zones, free elections in liberated Eastern Europe (a promise Stalin would break), Soviet entry into the war against Japan, and the creation of the United Nations.
The Potsdam Conference (July-August 1945) saw Truman replace Roosevelt and Attlee replace Churchill midway through. The atmosphere was more contentious. Agreements included German demilitarization, denazification, and reparations, but disagreements over Poland's borders and Eastern Europe foreshadowed the Cold War. Truman informed Stalin about the atomic bomb; Stalin already knew through Soviet espionage.
