In short: On April 25, 1974, Portuguese military officers launched a coup to topple the Estado Novo regime. What began as a strategic operation transformed into a popular revolution when civilians flooded the streets, offering carnations to soldiers. This peaceful uprising ended decades of authoritarian rule and a grueling colonial war.

The Carnation Revolution, or Operation Historic Turn, was orchestrated by the Armed Forces Movement (MFA) to dismantle the Estado Novo, an authoritarian regime established in 1933 under António de Oliveira Salazar. By the 1970s, the regime was severely strained by the Portuguese Colonial War, which had dragged on since 1961 and consumed up to 40 percent of the national budget. The war isolated Portugal internationally and created deep internal divisions, as military officers grew resentful of new laws that threatened their status and budget.

The coup itself was remarkably swift, lasting only 19 hours. It was triggered by two radio signals: the song 'E Depois do Adeus' followed by the banned protest song 'Grândola, Vila Morena'. Despite orders for civilians to remain indoors, thousands joined the military in the streets of Lisbon. The revolution earned its name from restaurant worker Celeste Caeiro, who distributed carnations to soldiers, leading others to place the flowers in the muzzles of guns. While the coup was largely bloodless, a violent confrontation at the headquarters of the political police, the PIDE, resulted in four civilian deaths.

The aftermath of the revolution was a period of intense political volatility known as the Ongoing Revolutionary Process. Portugal faced an economic crisis exacerbated by the return of over 1 million citizens from former African colonies, known as the retornados. The country navigated a complex transition, marked by the independence of territories like Angola and Mozambique, and a series of power struggles between leftist and centrist factions. It was not until the 1976 elections and the subsequent establishment of a constitutional government that the nation fully stabilized, eventually leading to Portugal's integration into the European Economic Community in 1986.

The revolution remains a pivotal moment in global history, often cited as the catalyst for the 'third wave' of democracy. While the pre-revolutionary era saw significant GDP growth, it was built on a foundation of political repression and colonial exploitation. The post-1974 period, though initially turbulent, fundamentally reshaped Portugal's social, economic, and political landscape, marking a definitive break from its authoritarian past.
