An often referred to occasion when discussing Iran’s[1] relation to Nazi Germany is the 1939 establishment of a scientific German library consisting of 7,500 books in Tehran. The books were a gift from Nazi Germany as a building block in a continuing collaboration between Iran and Germany. This Deutsche Wissenschaftliche Bibliothek, as it was called, contained a variety of selections ranging from the works of the great German philosophers to books of technological nature. More telling than the choice of books provided is the preface to the library catalog ordered by one of the Nazi’s chief racial ideologues, Alfred Rosenberg. In this text he writes: “National Socialist Germany is consciously devoted to the facilitation of Aryan culture and history and sees in Iran’s efforts a striving towards mutual goals, that are to further the spiritual affinity of both nations” (Vorwort, DWB).[2] This “spiritual affinity” (geistige Verwandschaft) has to be viewed as part of a continuation of successful German cultural work or Kulturarbeit in Iran, which is precisely what needs to be explored to understand how this point was reached. However, we need to look at a part of Germany’s robust cultural efforts in the earlier decades of the 1900s, especially throughout the First World War, to allow us to better comprehend the roots of this spiritual alliance between Germany and Iran.
