"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 . . . and the populations around them lie in what I must call the Soviet sphere, and all are subject, in one form or another, not only to Soviet influence but to a very high and in some cases increasing measure of control from Moscow."
—Winston Churchill

What effect did the Iron Curtain have on countries in Central and Eastern Europe?

Question 3 options:

It promoted travel to Western Europe

It hindered interaction with Western Europe

It increased trade with Western Europe

It prevented ideological conflicts with Western Europe

The Iron Curtain was set as an imaginary line between the two prevailing ideologies, the communism and the capitalism. On one side, the western, were the western democracies, while on the other side, the eastern one, were the communist countries. The western societies were mostly under the guidance and influence of the United States while the eastern societies were under the direct rule of the Soviet Union.

While the West wanted to promote trade and free communication and movement between the two sides, the Soviet Union didn't. The Soviet didn't wanted any western influence to shake up their rule and power so they stopped any movement of goods, ideas, and technology between the two sides. The people of many countries were not happy about this, especially in the cases of Poland, Czechoslovakia, and Hungary, the people revolted, but all revolts were suffocated brutally by use of violence and military force.
