It was, in the form of a physical barrier constructed in 1961, called the Berlin Wall, but was an iconic symbol of ideological division. It separated East and West Berlin and was both a practical and a political line dividing between communism of Eastern Europe headed by the Soviet Union and democracy of the western world led by United States of America and its allies. The Wall, kept East Germans from crossing over to the West, was a symbol of the cold harshness of communism, the fight for freedom,” during this period.

Cold War tensions, which may include diplomacy or spying, are seen by the existence of Red October-A event in which Soviet authorities tries to assassinate the Pope then topple Communism in Eastern Europe. The fall of the Wall in 1989 could also be said to have been a turning point to the end of Soviet influence in East Europe and an era of the Cold war. It signaled a course towards reunification in Germany and break up of the Eastern Europe block system.
