Winston Churchill Coined "Iron Curtain" in 1946 Fulton, Missouri Speech

The phrase "iron curtain" entered global vocabulary on March 5, 1946, when former British Prime Minister Winston Churchill delivered his "Sinews of Peace" address at Westminster College in Fulton, Missouri—with President Harry Truman on stage beside him.

The Key Passage

"From Stettin in the Baltic to Trieste in the Adriatic, an iron curtain has descended across the Continent. Behind that line lie all the capitals of the ancient states of Central and Eastern Europe... all are subject in one form or another, not only to Soviet influence but to a very high and, in many cases, increasing measure of control from Moscow."

Context

• Churchill was Leader of the Opposition (lost 1945 election)
• Invited by Truman (who endorsed the speech's spirit)
• Marked the public declaration of the Cold War by the West's most eloquent statesman
• Stalin denounced it as "warmongering"

Precedents

• 1918: Vasily Rozanov (Russian philosopher) used "iron curtain" metaphorically
• 1945: Goebbels (Nazi propaganda) used "eiserner Vorhang" for Soviet advance
• 1945: Churchill wrote to Truman: "An iron curtain is drawn down upon their front."

But the Fulton speech made it the defining metaphor of the East–West divide.

Impact

• Crystallized Western perception of Soviet bloc
• Accelerated Truman Doctrine (1947), Marshall Plan (1948), NATO (1949)
• Remained the central Cold War image until 1989

Churchill didn't invent the words—but he forged them into history.
