This article examines the life and works of Hossein Kazemzadeh Iranshahr, focusing on the evolution of his thought from an ardent nationalist to a cosmopolitan mystic. It offers a detailed account of the spiritual transformation that Iranshahr went through around 1920 in Europe—a topic that has never been addressed in existing scholarship. It contextualizes his esoteric views, especially the influence of Theosophy on his thought in the context of the so-called “Occult Revival” in Weimar Germany. Finally, it discusses how Iranshahr's emerging spiritual worldview impacted his intellectual outlook, especially his views on religion, nationalism, civilization, and race.
