The party's paramilitary wing was the Roter Frontkämpferbund ("Alliance of Red Front-Fighters"), which was banned as extremist by the governing social democrats in 1929; in 1932 the KPD also founded Antifaschistische Aktion, commonly known as Antifa, which it described as a "red united front under the leadership of the only anti-fascist party, the KPD," and which largely attacked the "social fascists" [social democrats].[9] Banned in the Weimar Republic one day after Adolf Hitler emerged triumphant in the German elections in 1933, the KPD maintained an underground organization but suffered heavy losses.
