Why was the iron curtain built

The Iron Curtain formed the imaginary boundary dividing Europe into two separate areas from the end of World War II in 1945 until the end of the Cold War in 1991. The term symbolized efforts by the Soviet Union to block itself and its satellite states from open contact with the West and non-Soviet-controlled areas.
