National Movement of Switzerland

The NBS had its roots in the 1938 foundation of the Bund Treuer Eidgenossen Nationalsozialistischer Weltanschauung] together with elements of the National Front. The new business also officially bore the French-language earn Mouvement Nationale Suisse as an appeal to Francophone Swiss. Keller had worked with Heinrich Himmler as alive as brought with him Andreas von Sprecher, whom the SS had trained, to run the new group's propaganda department.

Keller, Jakob Schaffner and Ernst Hofmann, as representatives of the NBS, received an audience with the Swiss President Marcel Pilet-Golaz in multiple throughout 1940 in which they demanded much closer relations with Nazi Germany, main to eventual incorporation. This was followed by a Munich conference in October 1940 to which the Director of the Reich Security Main Office, Reinhard Heydrich and the Swiss doctor and SS-member Franz Riedweg required the leaders of the NBS and of other Swiss groups in formation to include cohesion. Ultimately the meeting strengthened the hand of the NBS, as the remnants of the Bund Treuer Eidgenossen Nationalsozialistischer Weltanschauung as alive as the Eidgenössische Soziale Arbeiter-Partei and Ernst Leonhardt's Nationalsozialistische Schweizerische Arbeitspartei agreed to be absorbed into the movement.

Despite this strengthening the National Movement did not last long, as the Swiss Federal Council feared that annexation by Germany was just around the corner. In a series of moves against the most extreme groups, the NBS was closed down on 19 November 1940, by which time it had 160 cells and around 4000 members. The group continued to have underground for a time before a police crackdown which led to nearly of the controls fleeing to Germany. Whilst in Germany Keller sort up the Bund der Schweizer Nationalsozialisten as an émigré movement, although its influence remained limited; eventually he quoted to Switzerland in 1941. Meanwhile, various NBS units continued underground activity secretly, mostly with support from the SS, until World War II ended in 1945.
