The Carnation Revolution (), also known as the 25 April (), was initially a 25 April 1974 military coup in Lisbon which overthrew the authoritarian Estado Novo regime. The revolution began as a coup organised by the Armed Forces Movement (, MFA), composed of military officers who opposed the regime, but it was soon coupled with an unanticipated, popular civil resistance campaign. The revolution led to the fall of the Estado Novo, terminated the Portuguese Colonial War, and started a revolutionary process that would result in a democratic Portugal.
