The Iron Front (German: Eiserne Front) was a German paramilitary organization in the Weimar Republic which consisted of social democrats, trade unionists, and liberals. Its main goal was to defend liberal democracy against totalitarian ideologies on the far-right and far-left. The Iron Front chiefly opposed the Sturmabteilung (SA) wing of the Nazi Party and the Antifaschistische Aktion wing of the Communist Party of Germany.[1] Formally independent, it was intimately associated with the Social Democratic Party of Germany (SPD).
