Cold War Timeline

  • Creation of the United Nations

    In 1944, at the Dumbarton Oaks estate in Washington, D.C., delegates from 39 countries met to discuss the new organization, which was to be called the United Nations (UN).
  • Period: to

    Duration of the Cold War

  • The Yalta Conference

    With the war in Europe nearly over, Roosevelt, Churchill, and Stalin met at Yalta—a Soviet resort on the Black Sea—to plan the postwar world. Several agreements reached at Yalta later played an important role in causing the Cold War.
  • The Potsdam Conference

    In July 1945, with the war against Japan still raging, Truman finally met Stalin at Potsdam, near Berlin. Both men had come to Potsdam to work out a deal on Germany. Truman was now convinced that industry was critical to Germany’s survival. Unless its economy was allowed to revive, the rest of Europe would never recover, and the German people might turn to communism out of desperation.
  • UN Responses to the War

    In response to the atrocities of World War II, the United Nations held a General Assembly in December 1946. They passed a resolution that made genocide punishable internationally.
  • The Truman Doctrine

    Frustrated in Iran, Stalin turned northwest to Turkey. There, the straits of the Dardanelles were a vital route from Soviet ports on the Black Sea to the Mediterranean. For centuries Russia had wanted to control this strategic route. In August 1946, Stalin demanded joint control of the Dardanelles with Turkey.
  • The Long Telegram

    Increasingly exasperated by the Soviets’ refusal to cooperate, officials at the U.S. State Department asked the American Embassy in Moscow to explain Soviet behavior. On February 22, 1946, diplomat George Kennan responded with what became known as the Long Telegram
  • The Iron Curtain Descends

    After watching the Communist takeover in Eastern Europe, the former British prime minister Winston Churchill coined a phrase to describe what had happened. On March 5, 1946, in a speech delivered in Fulton, Missouri, Churchill referred to an “iron curtain” falling across Eastern Europe. The press picked up the term, and for the next 43 years, it described the Communist nations of Eastern Europe and the Soviet Union.
  • The Marshall Plan

    Meanwhile, postwar Western Europe faced grave problems. Economies were ruined, people faced starvation, and political chaos was at hand. In June 1947, Secretary of State George C. Marshall proposed the European Recovery Program, or Marshall Plan, which would give European nations American aid to rebuild their economies. Truman saw both the Marshall Plan and the Truman Doctrine as essential for containment. Marshall offered help to all nations planning a recovery program.
  • The Berlin Airlift Begins

    The Berlin Airlift began in June 1948 and continued through the spring of 1949, bringing in more than two million tons of supplies to the city.
  • The Berlin Airlift Ends

    Stalin finally lifted the blockade on May 12, 1949. The airlift symbolized American determination to contain communism and not give in to Soviet demands.
