The White Terror campaign refers to a series of violent actions and reprisals against perceived enemies of the state in post-World War II Europe, particularly in the context of civil wars or political upheaval. This campaign was primarily characterized by anti-communist sentiment, where right-wing groups targeted leftists, socialists, and communists, often using extrajudicial methods to instill fear and consolidate power. It played a significant role in shaping the political landscape of several countries during the Cold War period.
