"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. Warsaw, Berlin, Prague, Vienna, Budapest, Belgrade, Bucharest and Sofia; all these famous cities 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, 1946

"Here in Berlin, one cannot help being aware that you are the hub around which turns the wheel of history.... If ever there were a people who should be constantly sensitive to their destiny, the people of Berlin, East and West, should be they." - Martin Luther King, Jr.

The European continent was devastated in the wake of World War II, and the conflict left the Soviet Union and the United States as uncontested superpowers. This ushered in over 45 years of the Cold War, and a political alignment of Western democracies against the Communist Soviet bloc that produced conflicts pitting allies on each sides fighting, even as the American and Soviet militaries never engaged each other.

Though it never got "hot", the Cold War was a tense era until the dissolution of the USSR. And nothing symbolized the split more than the Berlin Wall, which literally divided the city. Berlin had been a flashpoint even before World War II ended, and the city was occupied by the different Allies even as the close of the war turned them into adversaries.
