Also wasn't it becoming popular among those esoteric proto fascists for quite a while by that point? People are acting like the Nazis just adopted all this stuff out of nowhere as if this wasn't contemporary with groups like the Thule society and a larger movement.

Germanenorden was a similar secret society with the same fucking ideals who monitored Jews, they adopted it in 1916, and the Order of the New Templars which followed Ariosophy used it in this context on their flag, I cannot find a date for their first usage, but they started it 1907. All of these groups knew each other, and had really close ties to Germanic and Nordic royals. The Thules where led previously by a Prince Gustav of Thurn and Taxis who got fucking owned by the Baravian soviet.

Yeah Rosen used it cause he liked runes......and also was a Nazi who used it as a symbol for literal National Socialist meetings he ran. Why are there like 4 people in this thread saying just "they had it first" as if that means anything given the context around the swastika in 1918
