 The area of these annexed territories was 94,000 square kilometres and the population was about 10 million, the great majority of whom were Poles.The annexed parts were controlled by a German administration ruled by a Gauleiter, a system similar in practice to that of the Reich itself.Nearly 1 million Poles were expelled from this German ruled area, while 600,000 Germans from eastern Europe and 400,000 from the German Reich were settled there.
