A new East German (DDR) flag is introduced. It features a hammer and a compass surrounded by a ring of rye. The hammer represented the workers in the factories. The compass represented the intelligentsia, and the ring of rye – the farmers. The display of the national emblem was for some years regarded as unconstitutional in West Germany and West Berlin and was prevented by the police. Only in 1969 did the West German government of Willy Brandt reverse this policy in what was known as Ostpolitik.
