At the end of World War II, Germany was divided into four military zones, the French, the British, the Americans and the Soviets, as well as the city of Berlin. Three million people went from East Germany and East Berlin to the west in a time period of 16 years. The wall was built to stop the departure of East Germans, thus becoming a symbol of their lack of freedom.
On the evening of November 9, 1989, the 155-kilometer Wall around the democratic enclave of West Berlin was unveiled. The border between East and West Germany, where Warsaw Pact and NATO tanks stood facing each other for decades, lost its meaning, as did the socialist state of Germany.
