The Three Arrows (German: Drei Pfeile) is a social democratic political symbol associated with the Social Democratic Party of Germany (SPD), used in the late history of the Weimar Republic. First conceived for the SPD-dominated Iron Front as a symbol of the social democratic resistance against Nazism in 1932, it became an official symbol of the Party during the November 1932 German federal election, representing their opposition towards monarchism, Nazism, and communism.[1]
