August 1961.
After 1945 partition of Germany, there is 2 Germany : West Germany administrated by the UK,USA, and France, just like a triumphant capitalism, and East Germany,Soviet model administrated by the USSR, capital East Berlin. Because of the bad economy of East Germany and the communism which is only accepted by a minority, the emigration westward does a jump forward.
Borders of both Germany are under control but in Berlin people can move freely among both Berlin. During the first week of August, the daily average of the refugees increases enormously. To prevent the bleeding of emigration, KRUTCHEV, president of the USSR, erects the Berlin Wall on August the 13th.
