Ariosophy and Armanism are esoteric ideological systems that were largely developed by Jörg Lanz von Liebenfels and Guido von List, respectively, in Austria between 1890 and 1930. The term 'Ariosophy', which translates to wisdom of the Aryans, was invented by Lanz von Liebenfels in 1915, and during the 1920s, it became the name of his doctrine. For research on the topic, such as Nicholas Goodrick-Clarke's book The Occult Roots of Nazism, the term 'Ariosophy' is generically used to describe the Aryan/esoteric theories which constituted a subset of the 'Völkische Bewegung'. This broader use of the word is retrospective and it was not generally current among the esotericists themselves. List actually called his doctrine 'Armanism', while Lanz used the terms 'Theozoology' and 'Ario-Christianity' before the First World War.
