Membership pin of the Tannenberg-Bund (Hü 5102 a). On safety pin, marked with the manufacturer. Silvered and enameled.

The Tannenbergbund was a nationalist German political society formed in September 1925 at the instigation of Konstantin Hierl under the patronage of the former German Army general Erich Ludendorff. Part of the Völkisch movement, it was meant to counteract the Der Stahlhelm veterans association as well as the reorganized Sturmabteilung (SA) of the Nazi Party. The TB failed to meet the goal of a far-right collective movement and sank into insignificance long before it was officially banned by the Nazi authorities in September 1933.
