when was the cold war

The Cold War is usually dated from about 1947 to 1991.

Quick Scoop

Most historians say the Cold War began in the late 1940s , shortly after World War II ended in 1945, as tensions grew between the United States and its Western allies on one side and the Soviet Union and its allies on the other. It is commonly considered to have ended in 1991 , when the Soviet Union dissolved and the bipolar world order collapsed.

Key date ranges people use

• Common textbook range: 1947 (early Truman-era confrontations and use of the term “Cold War”) to 1991 (collapse of the USSR).

• Broader start view: “From the end of World War II in 1945” until the early 1990s, emphasizing that tensions began as soon as the war ended and the postwar order was being negotiated.

• Symbolic end moments:
  • 1989: Fall of the Berlin Wall and Eastern European revolutions.

* 1990–1991: German reunification, then the official dissolution of the Soviet Union in December 1991.
