I’m sure that many of you will know how all this came about, but I think it’s worth repeating anyway.
The background to the drama goes back to the end of WWII when Germany was divided up by the four main countries responsible for its defeat – Britain, France, the United States and the Soviet Union. Although they were united in defeating Nazi Germany, the differences in ideology between the Western Powers and the Soviet Union had been obvious for quite some time. Really, it was just a case of agreeing to disagree while they defeated the common enemy of Nazi Germany.
At the end of the war Germany was divided up into West Germany, (controlled by the Western alliance), and East Germany (controlled by the Soviet Union). Berlin, which was situated deep inside the Soviet sector, was also divided up by the victors into West and East Berlin.
