The Berlin Wall served as a monumental physical reminder of the differences in government between East and West Germany. After World War Two, there was a division of Germany between the Western Allied forces of the US, Britain and France and the Soviet Union in the East. Each assumed responsibility for a portion of Germany to help it back on its feet after the war. No one thought the separation would last for more than a year. Yet it lingered for the next four-and-a-half decades.The tension which sparked the construction of the Berlin Wall occurred soon after World War Two ended. After the war, Germany was divided up into four zones, with the British, the Americans, the French and the Soviet Union each responsible for running a zone. The German capital of Berlin, although in the Soviet zone of Germany, was likewise divided into four sectors. As firm allies, the US, Britain and France worked closely with each other to bring about changes to their zones and sectors in Germany.
