The one Germanic-language speaking country that was not included in the Pan-Germanic unification aim was the United Kingdom,[94] in spite of its near-universal acceptance by the Nazi government as being part of the Germanic world.[95] Leading Nordic ideologist Hans F. K. Günther theorized that the Anglo-Saxons had been more successful than the Germans in maintaining racial purity and that the coastal and island areas of Scotland, Ireland, Cornwall and Wales had received additional Nordic blood through Norse raids and colonization during the Viking Age, and the Anglo-Saxons of East Anglia and Northern England had been under Danish rule in the 9th and 10th centuries.[96] Günther referred to this historical process as Aufnordung ("additional nordification"), which finally culminated in the Norman conquest of England in 1066.[96] Britain was thus a nation created by struggle and the survival of the fittest among the various Aryan peoples of the isles, and was able to pursue global conquest and empire-building because of its superior racial heredity born through this development.[97]
