雅利安人種
A great deal of time and resources were spent on researching or creating a popularly accepted “historical”, “cultural” and “scientific” background so the ideas about a “superior” Aryan race could be publicly accepted. For example, an expedition to Tibet was organized to search for the origins of the "Aryan race". To this end, the expedition leader, Ernst Schäfer, had his anthropologist Bruno Beger make face masks and skull and nose measurements. Another expedition was sent to the Andes.
