The Iron Curtain was widely used to describe the boundary, both physical and political, which divided Europe following the end of WW2 until the end of the Cold War in 1991.

On March 5th 1946 Winston Churchill gave a speech that is widely attributed to be the reason that the phrase ""Iron Curtain"" became a symbol of the Cold War. Originally the term was used to refer to fireproof theatre curtains.
