In "Mein Kampf", Hitler described children resulting from marriages to African occupation soldiers as a contamination of the Aryan race "by Negro blood on the Rhine in the heart of Europe." He thought that "Jews were responsible for bringing Negroes into the Rhineland, with the ultimate idea of bastardizing the white race which they hate and thus lowering its cultural and political level so that the Jew might dominate." He also implied that this was a plot on the part of the French, saying the population of France was being increasingly "negrified".
