Anti-fascism is the opposition to fascist ideologies, groups and individuals. The related term antifa derives from Antifaschismus, which is German for anti-fascism; it tends to refer to individuals and groups on the left of the political spectrum, that are dedicated to fighting fascism.
The term "Anti-Fascist" was also commonly used by Benito Mussolini's Fascist regime in Italy, to describe its opponents; in this usage the term obviously carried negative and pejorative connotations. Mussolini's secret police was officially known as Organizzazione per la Vigilanza e la Repressione dell'Antifascismo (OVRA), Italian for "Organization for Vigilance and Repression of Anti-Fascism").
