The main topic of this master's thesis is, as the title itself says, devolving into deeper studies of the occult roots of National Socialism based on the available literature on the topic itself. The work is conceived as a chronological synthesis of several aspects of the influence of occultism and esotericism on the development of National Socialist ideology. Essentially, this work is divided into several parts that serve as the foundations of the complex mosaic that this topic certainly is. The first part introduces the reader to the socio-political situation in the Austro-Hungarian Monarchy in the second half of the 20th century. Highlighting this historical context is important for a full understanding of the time in which occult ideas flourished after several centuries of complete dominance by Judeo-Christian theology. It is extremely important to understand the political climate in which völkisch nationalism and pan- Germanism, which are the foundations of National Socialist ideology, developed. After all, Adolf Hitler himself is a native Austrian who felt firsthand the chaotic climate of Vienna at the beginning of the 20th century, and the thoughts he formed during his lifetime are directly related to the revival of occult practices in the area where German people lived inside of Austria-Hungary. Following such a thought, the first part will deal with the emergence and development of völkisch nationalism and pan-Germanism as key political ideologies influenced by esotericism. This is much more important than it is usually presented in popular works dealing with the history of the development of National Socialism. The second part directly touches on a more detailed explanation of occultism and the branches within occultism that are important for the mentioned period of the end of the 19th and the beginning of the 20th century. Without understanding what the occult really is and how Western esotericism and theosophy influenced the development of National Socialism, it is difficult to understand the genocidal nature of the Nazi regime. Precisely because of this, great attention was paid to the minute details of theosophy as a specific occult phenomenon that both directly and indirectly formed the National Socialist worldview. This part of the text is certainly the most controversial since it is shrouded in pseudoscience, but it is absolutely unavoidable for understanding the fullness of the topic being written about. The third part deals with Ariosophy and Arminianism, concepts that synthesize theosophy with a kind of nostalgia for pagan times. Here, the topic is somewhat more directly related to the origin of National Socialism itself, since scholars from these fields of pseudoscience and pseudophilosophy not only influenced the development of National Socialist thought, but were also part of the same movement. Here, classic anti-Semitism and the idea of blood and soil take their basic contours. The fourth part deals with two organizations that directly influenced the creation of the National Socialist German Workers' Party - the Germanenbund and the Thule Society. Using the links from the previous parts, this part will chronologically follow the development of these two organizations with the aim of crystallizing and achieving a clear understanding of what Hitler and his clique will not only promote, but also implement in reality. Finally, the fifth part deals with the very origin of the Nazi political organization with a specific insight into the ideological and occult constructions of the members of that movement, but also with a special insight into Hitler's supernatural imaginary. This completes the story of the party that, 12 years after the appointment of Hitler as its leader, will take over power in Germany and create a system that its ideological and philosophical predecessors dreamed of at the end of the 19th and beginning of the 20th century, and which, driven by these attitudes, will launch the ideas of the Holocaust and Lebensraum. The purpose of this work is to show and argue the position that the most important foundations of National Socialism are deeply immersed in pseudoscience and occultism, and not in dry political theory.
