Culture definitions for iron curtain

Iron Curtain

The former division between the communist nations of eastern Europe — the Eastern Bloc — and the noncommunist nations of western Europe. The term refers to the isolation that the Soviet Union imposed on its satellites in the Eastern Bloc and to the repressive measures of many Eastern Bloc governments. (See Berlin Wall (see also Berlin Wall) and cold war.)

Note

The expression Iron Curtain was coined by Winston Churchill, who was prime minister of Britain in World War II. Churchill first used the term soon after the war, when the Soviet Union was beginning to carry out its plans for postwar dominance of eastern Europe.
