Nazism and occultism describes a range of theories, speculation and research into the origins of Nazism and its possible relation to various occult traditions. Such ideas have been a part of popular culture since at least the early 1940s, during World War II, and gained renewed popularity starting in the 1960s. There are documentaries and books on the topic, among the most significant are The Morning of the Magicians (1960) and The Spear of Destiny (1972).
