The Cold War was a clash of ideologies and battles for influence ranging all over the world. In late 1961 matters became very heated in Berlin, East Germany. Berlin was located in the Soviet controlled part of Germany but was divided into four sectors: US, UK, French, and Soviet. "The wall separated East Germany from West Germany for more than a quarter-century, from the day construction began on August 13, 1961 until the Wall was opened on November 9, 1989."
