Nazi Leadership and the Thule Society Frank JACOB The intention of the essay is to outline the connections of leading Nazis with the Thule Society. This völkisch organization was a secret society, which was an offshoot of the Germanenorder and secretly fought against the government of the Munich Soviet republic in the days after World War I. The leader of this society, Rudolf von Sebottendorff, tried to underline its important role for the genesis of National Socialism, because Thule members were the first ones, who supported Hitler on his way to power. His book was banned by the Nazi leadership right after its publication. So there might be some truth in the writings of Sebottendorff. To make a proof of this claim, there will be biographical analysis of Gottfried Feder (1883-1941), Alfred Rosenberg (1893-1946), Dietrich Eckart (1868-1923), Hans Frank (1900-1946), and Rudolf Hess (1894-1987). All of them had contacts to the Thule Society. The first three persons were just guests, but Frank and Hess were members of the secret society. The central point of the present essay is whether the leading Nazis of the 1920s had close connections with the Thule Society, and if there was an influence of the Thule Society on Hitler and the German National Socialistic Workers’ Party.
