Der Stahlhelm, Bund der Frontsoldaten, commonly known as Der Stahlhelm, was a German First World War veteran's organisation existing from 1918 to 1935. In the late days of the Weimar Republic, it was closely affiliated to the monarchist German National People's Party (DNVP), placed at party gatherings in the position of armed security guards.

The German National People's Party was a national-conservative and monarchist political party in Germany during the Weimar Republic. Before the rise of the Nazi Party, it was the major nationalist party in Weimar Germany. It was an alliance of conservative, nationalist, monarchist, völkisch, and antisemitic elements supported by the Pan-German League. Ideologically, the party was described as subscribing to authoritarian conservatism, German nationalism, monarchism, and from 1931 onwards also to corporatism in economic policy. It held anti-communist, anti-Catholic, and antisemitic views. On the left–right political spectrum, it belonged on the right-wing, and is classified as far-right in its early years and then again from the late 1920s when it moved back rightward.
