The Sig rune is one of several Germanic runic letters adopted by the SS, the Nazi paramilitary organisation.
Symbols resembling the Sig rune (e.g., lightning bolts; a stylised italicised “S”) can also sometimes appear in non-hateful contexts. As such, its use should always be identified and evaluated in context.
These runes were based on older Germanic runic alphabets, which were popularised in the late 19th and early 20th century by German nationalist figures before being co-opted by the Nazis, particularly the SS. Runic letters continue to be used by neo-Nazi groups internationally.
The Sig rune is mostly widely known as the symbol of the SS, in the form of two Sig runes side by side resembling two lightning bolts .
For hate groups, the Sig rune is intended to represent victory.
