Portugal’s Carnation Revolution Ends a Dictatorship Almost Without Bloodshed

Late on the evening of 24 April 1974, a Lisbon radio station broadcast Portugal's entry in the Eurovision Song Contest, Paulo de Carvalho's song E Depois do Adeus. The broadcast served as a prearranged signal to rebel military units across the country. Just past midnight, another station aired Zeca Afonso's politically charged ballad Grandola, Vila Morena, directing conspirators to seize strategic centers of authority. Within hours, the Armed Forces Movement mounted an armed uprising that rapidly dismantled Western Europe's longest-standing authoritarian dictatorship.

The coup struck against the Estado Novo, an authoritarian framework established by Antonio de Oliveira Salazar in the 1930s and inherited by Marcelo Caetano in 1968. By the early 1970s, Portugal was caught in protracted colonial warfare across Angola, Mozambique, and Portuguese Guinea, spending a heavy share of its state budget on the fighting. Discontent among younger officers intensified when the regime enacted measures equating brief militia training with traditional military academy credentials, accelerating the formation of the underground Armed Forces Movement.
