The Occult Roots of Nazism

The Occult Roots of Nazism: The Ariosophists of Austria and Germany, 1890–1935, later published under the title The Occult Roots of Nazism: Secret Aryan Cults and Their Influence on Nazi Ideology, is a book about Ariosophy and Nazi occultism by historian Nicholas Goodrick-Clarke, who traces some of its roots back to esotericism in Germany and Austria between 1880 and 1945. The foreword is by Rohan Butler, who had written The Roots of National Socialism in the 1930s. The book is based on Goodrick-Clarke's 1982 Ph.D. thesis.

It was first published by The Aquarian Press in 1985, and republished in paperback form by New York University Press in 1992. The book was highly regarded upon its publication and has been called the seminal work on the topic of Nazism and occultism and as Goodrick-Clarke's most influential work. It received praise for being a serious scholarly effort on a subject which otherwise attracted many fringe or mythical claims.
