Antifaschistische Aktion

Antifaschistische Aktion (German: [ˌantifaˈʃɪstɪʃə ʔakˈtsi̯oːn], lit.'Anti-fascist Action') was an anti-fascist organisation in the Weimar Republic, that was founded and controlled by the Communist Party of Germany (KPD). Antifaschistische Aktion opposed pro-Nazi paramilitary forces, like the Sturmabteilung (SA). The group's KPD leadership strongly opposed the Social Democratic Party of Germany (SPD), although local Antifaschistische Aktion groups worked with SPD activists.

In the postwar era, the historical organisation has inspired new groups and networks, including the German antifa movement, many of which use the aesthetics of Antifaschistische Aktion, especially the antifa moniker and logo.
