Kampfbund für deutsche Kultur
Helm adhered to a national conservative ideology throughout his life, expressing sympathy for the German National People's Party (without however becoming a regular member). He was a member of the Militant League for German Culture from 1933, but he never became a member of the Nazi party. In November 1933 Helm signed the "Vow of allegiance of the Professors of the German Universities and High-Schools to Adolf Hitler and the National Socialistic State".
