Tehran Conference Between the Allies’ “Big Three” Leaders

The Tehran Conference, also known as the Eureka Conference, was a critical meeting held during World War II between the “Big Three” Allied leaders: British Prime Minister Winston Churchill, U.S. President Franklin D. Roosevelt, and Soviet Premier Joseph Stalin November 28 – December 1, 1943. The conference occurred in Tehran, Iran, from November 28 to December 1, 1943.

The Tehran Conference focused on coordinating military strategy and discussing the opening of a second front against Nazi Germany. The major decisions made during the conference included:

  • A promise from the Soviet Union to enter the war against Japan once Germany was defeated.
  • The recognition of Iran’s independence and the importance of providing economic assistance to the country.
  • Discussions on post-war arrangements, including the division of Germany, the creation of a United Nations organization, and Soviet influence in Eastern Europe.
  • The Tehran Conference was held at the Soviet Embassy, with each leader staying in a separate residence for security reasons.
  • The nickname “Eureka” was derived from a comment made by Churchill, who reportedly exclaimed, “Eureka!” when the decision was made to launch Operation Overlord.
