The NBS had its roots in the 1938 foundation of the Bund Treuer Eidgenossen Nationalsozialistischer Weltanschauung by Rolf Henne after the more moderate Robert Tobler had removed Henne from the leadership of the National Front.[1] In 1940, the Bund absorbed a number of tiny Nazi-supporting organisations to become the NBS under Henne and Dr. Max Leo Keller.
