East Berlin
East Berlin was eastern part of the city of Berlin (in 1948 forcibly split into West Berlin and East Berlin during the Soviet Berlin Blockade) that served as the capital of the German Democratic Republic until the partial reunification of Germany in 1990. Many East Germans did not want to live in a communist country and crossed into West Berlin, where they could either settle or find transportation to West Germany and beyond. By 1961, four million East Germans had moved west. This exodus illustrated East Germans' dissatisfaction with their way of life, and posed an economic threat as well, since East Germany was losing its workers.
