Following the German invasion of Britain in 1940, the UK was divided into occupied and unoccupied zones. However it was decided that Britain should be reunified into a new nation. From the Autumn of 1941 the British Union of National Socialists began taking on some administrative duties. In November 1941 their leader, Oswald Mosley, went to Berlin to visit Hitler, where he was able to persuade him to make him Leader of a new British State.
