# Potsdam Conference

> Allied leaders redrew Polish borders, shifting the nation westward and ceding eastern territories to the Soviet Union, reshaping Central European geography.

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.

## Summary

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.

- **1945 - Division of Germany into occupation zones**: Four-power occupation agreement led to partition of Germany; Soviet zone eventually became East Germany in 1949, deepening Cold War divisions
- **1945 - Japanese surrender terms finalized**: Conference confirmed unconditional surrender demand for Japan; Soviet commitment to enter Pacific War within 90 days formalized, leading to Soviet invasion of Manchuria in August
- **1945 - Council of Foreign Ministers created**: Potsdam established mechanism for managing European peace treaties, though deep disagreements emerged immediately over Soviet influence in Eastern Europe

## Then vs now

- **German territory under Soviet control**: 1945: ~43% of prewar Germany → 2024: 0% - Soviet zone became East Germany until 1990 reunification
- **Poland's western border distance from Berlin**: 1945: ~160 km → 2024: ~160 km - Oder-Neisse Line established at Potsdam; Poland shifted westward, Germany lost eastern territories
- **US-Soviet alliance status**: 1945: Active wartime partners → 2024: Strategic adversaries - Cold War tensions began emerging even during the conference itself

## Voices

- **Winston Churchill, UK Prime Minister** (official, supportive) - Speech to House of Commons, August 1945
  > We have done our best to save the world from the errors and tragedies of the past. The settlement we have reached protects the peace and justice that our peoples have fought for.
- **Harry S. Truman, US President** (official, celebratory) - Radio address to American people, August 1945
  > The three great powers have agreed on the essential matters. We shall maintain the unity that has won the war and will win the peace.
- **Anne O'Hare McCormick, New York Times columnist** (media, skeptical) - New York Times, August 5, 1945
  > The Potsdam settlement is less a peace than a postponement. The Western leaders have handed Eastern Europe to Stalin's sphere, and Poland pays the price with territory lost and gained.
- **Vyacheslav Molotov, Soviet Foreign Minister** (official, supportive) - Soviet government communique, August 2, 1945
  > DE: 'Die Sowjetunion hat ihre Grenzen gesichert und ihre Einflusssphare erweitert.' / EN: 'The Soviet Union has secured its borders and expanded its sphere of influence according to its security needs.'
- **George Orwell, British writer and political commentator** (analyst, dismissive) - Tribune magazine, August 1945
  > Poland's frontier shifts westward, but she remains under the heel of a great power. We have traded one form of domination for another - and called it peace.

## Impact

Potsdam cemented the Soviet sphere of influence over Eastern Europe and formalized the division of Germany that would define Cold War tensions for 45 years. The conference also accelerated Japan's defeat by securing Stalin's commitment to enter the Pacific War, reshaping the balance of power across two continents.
