Shortly after being introduced to Reichsführer-SS Himmler in September 1933 at a conference of the "Nordische Gesellschaft", Wiligut was inducted into the SS (under the pseudonym "Karl Maria Weisthor") to head a Department for Pre- and Early History which was created for him within the SS Race and Settlement Main Office (RuSHA). In April 1934 he was promoted to the SS equivalent of his old colonel rank (Standartenführer), and then made head of Section VIII (Archives) for RuSHA in October 1934. In November 1934 a promotion followed to the rank of Oberführer (lieutenant-brigadier), and then in the spring of 1935 Wiligut was transferred to Berlin to serve on Himmler's personal staff. He was promoted to the rank of Brigadeführer in September 1936.
