The Mystery of the Carnations: A Silent Revolution and a Persistent Enigma

The history of Portugal, especially that of the 20th century, is marked by an event of seismic magnitude: the Carnation Revolution, which took place on April 25, 1974. A military uprising that ended 48 years of the Estado Novo dictatorship, paving the way for democracy. However, behind the iconic image of red carnations offered by soldiers to the crowds, lies a mystery that has persisted for nearly five decades: who, in fact, orchestrated the operation in its darkest corridors? What was the true extent of the planning, and who were the real architects behind the coup that changed the destiny of a nation?

1. The Context and the Incident: The Beginning of a Mystery

The Estado Novo regime, founded by António de Oliveira Salazar and continued by Marcelo Caetano, was marked by authoritarianism, censorship, and involvement in grueling colonial wars in Africa. Social and military discontent was growing, fueled by a lack of prospects and political oppression. It was in this climate of latent tension that a group of Army officers, dissatisfied with the situation, began to conspire.

The spark for the revolution was the signal broadcast by the Rádio Renascença station, which aired the song "E Depois do Adeus" by Paulo de Carvalho around 10:55 PM on April 24, 1974. This was the first signal, indicating that the operation was about to begin. Hours later, at 12:20 AM on April 25, 1974, the second and definitive password was given by the same radio station with the song "Grândola, Vila Morena" by Zeca Afonso. From that moment on, military units revolted in various parts of the country, especially in Lisbon.

What followed was a succession of rapid and, in many respects, unexpectedly peaceful events. Forces loyal to the regime did not offer significant resistance, and Marcelo Caetano eventually surrendered, handing over power to an Army general, António de Spínola. The mystery, however, lies not only in the speed and relative absence of violence, but in the complex webs of influence and planning that led to this outcome.

2. Timeline of Key Events

• Late 1973: Formalization of the Captain's Movement, a group of low-ranking officers (captains) seeking to overthrow the regime.
• March 26, 1974: A frustrated military coup attempt, known as the March 26. This attempt, despite failing, served as a catalyst and accelerated the plans of the Captain's Movement.
• April 24, 1974, 10:55 PM: Broadcast of the song "E Depois do Adeus" by Rádio Renascença, the first signal for the start of the operation.
• April 25, 1974, 12:20 AM: Broadcast of the song "Grândola, Vila Morena" by Rádio Renascença, the definitive signal for the start of the Carnation Revolution.
• April 25, 1974 (morning/afternoon): Military units occupy strategic points in Lisbon and other cities. Armed Forces loyal to the regime offer no organized resistance.
• April 25, 1974: Marcelo Caetano surrenders and hands over power to General António de Spínola, ensuring the safety of the members of the deposed government.
• April 26, 1974: The National Salvation Junta assumes power, led by General António de Spínola.
• May 1, 1974: First major popular demonstration in favor of democracy, where carnations begin to be distributed and associated with the revolution.

3. The Main Theories

The nature of the Carnation Revolution, with its relative absence of bloodshed and the speed of its completion, has been the subject of intense debate and theories. Explanations range from the most pragmatic and historical to the most speculative.

3.1. The Captain's Movement Theory (Scientific/Historical Hypothesis)

This is the most widely accepted theory, supported by documentary and testimonial evidence. It argues that the Carnation Revolution was essentially orchestrated by the Captain's Movement, an organized group of military officers dissatisfied with the regime. These officers, motivated by the colonial war, censorship, and lack of career prospects, drew up a detailed plan to overthrow the government. The choice of songs as signals, the coordination of military units, and the call to disobey repression orders are seen as proof of meticulous planning.

• Evidence: Declassified documents, memoirs of involved officers (such as Vasco Lourenço and Otelo Saraiva de Carvalho), and intelligence reports from the time.
• Strengths: Explains the military organization, coordination, and absence of resistance.

3.2. The External Influence Theory (Conspiracy/Historical)

This theory suggests that, although the Captain's Movement was the executor, there were significant influences from foreign powers, particularly the United States and the United Kingdom, which desired the end of the Salazarist regime and, consequently, the end of the Portuguese Colonial War in Africa, which would facilitate the independence of the colonies and the withdrawal of Soviet influence. Another strand of this theory points to the influence of the Soviet Union, which saw the revolution as an opportunity to expand its influence in Portugal.

• Evidence: Rumors and speculation about contacts between Portuguese officers and foreign embassies, and foreign intelligence reports from the time that monitored the situation in Portugal.
• Strengths: Could explain the relative ease with which the coup succeeded and the absence of military intervention by other countries in defense of the regime.
• Controversies: Lack of concrete and irrefutable proof of direct and planned intervention by foreign powers in the timing and execution of the coup.

3.3. The Theory of Unexpected Conjuncture and "Spontaneous Revolution" (Speculation)

Some argue that, although there was discontent, the Carnation Revolution was more of an explosion of opportunities and situational factors than a rigidly executed plan. The theory suggests that the Captain's Movement took the first step, but the massive participation of the population and the hesitation of forces loyal to the regime were determining factors that went beyond the original plan. General Spínola himself, a figure with ties to the regime but who became a bridge for the transition, is seen by some as an element who navigated the situation rather than an initial planner.

• Evidence: The spontaneity with which civilians joined the troops in the streets, the absence of a clear plan for the post-coup period that had been widely disclosed before the event.
• Strengths: Explains popular participation and the festive nature the revolution acquired.
• Controversies: Ignores the prior organization and meticulousness of the Captain's Movement.

3.4. Paranormal or Supernatural Theories (Paranormal)

Although extremely marginal and without any scientific or factual support, there are fringe theories that attribute the smoothness and success of the revolution to inexplicable factors, such as extraordinary synchronicities or even "esoteric" influences. These theories generally arise in contexts of searching for explanations for high-impact events that defy conventional logic.

• Evidence: None.
• Strengths: None.
• Controversies: Completely devoid of empirical basis.

4. Controversies and Blind Spots

Despite the relative clarity surrounding the events of April 25, controversies and blind spots persist that fuel the mystery surrounding the Carnation Revolution:

• The Exact Role of General Spínola: Although he was the face of the transition, what was his prior involvement in the planning of the coup? Was he a choice of the Captain's Movement, or an element who took advantage of the situation? Documents and testimonies still raise questions about his real position before and during the events.
• The Silence of Loyal Forces: Why did the armed forces loyal to the regime not offer organized resistance? Were there specific orders not to react, or was it simply a moral and logistical collapse? The absence of a more robust military confrontation is one of the most intriguing aspects.
• Hidden Agendas: Although the Captain's Movement was the main driver, it is agreed that other groups, such as the Portuguese Communist Party (PCP) and the Portuguese Democratic Movement (PIDE/DGS), also played an influential role, trying to shape the developments of the revolution according to their interests. The extent of this influence and the coordination between these groups is a constant point of debate.
• Ignored Clues and Lost Evidence: As with any large-scale event, it is likely that some clues have been ignored, testimonies forgotten, or evidence lost over time, which makes a perfectly exhaustive reconstruction difficult.
• The True Identity of the "Carnations": Although the red carnation became the symbol of the revolution, its exact origin as a peaceful symbol has different versions. One points to Maria Margarida de Almeida, a flower seller who allegedly distributed the carnations to soldiers on the afternoon of April 25, a gesture that was widely publicized and adopted. However, some point to other details about the initial distribution.

5. Curiosities and Legacy

The Carnation Revolution transcended the political sphere and became a cultural landmark in Portugal and the world:

• The Symbol of the Carnation: The image of soldiers with carnations in their rifles became a universal symbol of a peaceful and democratic revolution. The story of how the carnations appeared on the weapons is not entirely clear, but their instant adoption transformed them into an icon of freedom.
• The End of the Portuguese Empire: The Carnation Revolution was the catalyst for the decolonization of Portuguese colonies in Africa (Angola, Mozambique, Guinea-Bissau, Cape Verde, and São Tomé and Príncipe), forever changing the geopolitical map of Africa.
• The Transition Period (PREC): The period that followed the revolution, known as the Ongoing Revolutionary Process (PREC), was marked by political instability, radicalization, and attempted coups d'état, before the consolidation of democracy with the approval of the 1976 Constitution. This period is also the subject of extensive research and debate.
• Current Status of the Case: The Carnation Revolution, as a historical event, is a widely studied and documented chapter. However, its "mysteries" lie in the lines of power, hidden intentions, and the complexity of alliances. It is not an unsolved criminal case, but a historical enigma whose nuances and characters continue to be unraveled by historians and researchers. Declassified archives continue to be analyzed, and new perspectives emerge, maintaining the fascination with this decisive moment in Portuguese history.

The Carnation Revolution, with its aura of mystery and its undeniable historical importance, remains a fascinating topic, a testament to a people's ability to reclaim their freedom, and a reminder that, even in the most glorious moments, hidden forces and the complexities of power are rarely fully revealed.
