Following the ideas of Gobineau and others, the Nazi theorist Alfred Rosenberg determined that these people, who, he claimed, were originally from Atlantis, were a dynamic warrior people who dwelt in northern climates on the North German Plain in prehistoric times, from which they migrated southeast by riding their chariots, eventually reaching Ukraine, Iran, and then India. They were supposed to be the ancestors of the ancient Germanic tribes, who shared their warrior values. Rosenberg opposed Christianity because to him, it was an alien Semitic slave-morality which was inappropriate for the warrior Aryan master race and in its place, he supported a melange of aspects of Hindu Vedic and Zoroastrian teachings (both of these religions were organised by Aryans), along with pre-Christian European Odinistic paganism, which he also considered distinctively Aryan in character.
