September 11, 2026 — Anniversary of the Coup in Chile: History and Remembrance of the Victims
Every year on September 11, Chile commemorates the events of the 1973 military coup, when the army overthrew the democratically elected President Salvador Allende. On that day, the military attacked the La Moneda presidential palace, and after Allende’s death, a military junta led by Augusto Pinochet came to power. This date has come to symbolize the rupture in the country’s democratic life and serves as a memorial to the thousands of people who were killed, arrested, tortured, disappeared, or forced to flee Chile.
The anniversary of the military coup in Chile is observed on September 11. The year 2026 will mark the 53rd anniversary of the events that became one of the most dramatic moments in the country’s modern history. It is not a holiday in the traditional sense. The day is associated primarily with remembrance, mourning, historical discussions, and honoring those who fell victim to repression during the military dictatorship. Over the years, Chilean authorities have held official ceremonies, moments of silence, wreath-laying ceremonies, and other commemorative events. In 2023, on the 50th anniversary of the coup, the government declared September 11 an official day of mourning in memory of the victims.
The topic of September 11 remains a very sensitive one for Chilean society. The country is still home to the families of those who were killed or went missing, as well as those who survived imprisonment, torture, or exile. Therefore, on this day, people speak not only about the coup itself but also about its consequences for several generations of Chileans.
What Happened on September 11, 1973
On the morning of September 11, 1973, President Salvador Allende arrived at the La Moneda presidential palace in Santiago after receiving word of a naval uprising in Valparaíso. At approximately 9 a.m., the military issued its first order, demanding that the president step down and transfer power to a military junta. The junta consisted of Army Commander Augusto Pinochet, Navy Commander José Toribio Merino, Air Force Commander Gustavo Ley, and Carabineros Commander César Mendoza. Allende refused to leave the presidential palace. In his final radio address, he stated: “I declare my unwavering determination to continue defending Chile, its prestige, its traditions, its legal norms, and its Constitution.” Following this, fighting broke out around La Moneda.
Around noon, the military air force launched an attack on La Moneda. Hawker Hunter aircraft fired missiles at the presidential palace, after which a fire broke out in the building. The military seized the palace, and Salvador Allende died inside the building. According to the National Library of Chile, after the seizure of La Moneda, a military junta was formed, which took power in the country.
Why the Military Coup Happened
The coup was preceded by a prolonged period of political and economic crisis. Salvador Allende became president in 1970 as the candidate of the left-wing “Popular Unity” coalition. His government implemented large-scale social and economic changes, including the nationalization of some enterprises and the expansion of land reform. These changes provoked strong resistance from parts of the business community, conservative political forces, and representatives of the middle and upper classes. At the same time, the country faced economic difficulties, shortages of certain goods, strikes, and political confrontation. The opposition in parliament blocked some of the government’s initiatives, and society became increasingly divided.
Tensions were also rising within the armed forces. Some military personnel advocated for the preservation of constitutional order, while others were preparing a violent seizure of power. According to the Chilean National Library, preparations for the coup had been underway since 1972 and included political pressure, destabilization, and various coercive measures. The United States also played a significant role in these events. The issue of American intervention in Chile’s political crisis remains a major separate topic in the history of the coup. It is known that U.S. intelligence agencies and the administration of President Richard Nixon sought to prevent the Allende government from consolidating its power and supported actions aimed at exerting political pressure on his administration.
Who Came to Power After the Coup
After Allende’s overthrow, a military junta took power. Initially, it consisted of four representatives from various security forces—Augusto Pinochet from the army, José Toribio Merino from the navy, Gustavo Ley from the air force, and César Mendoza from the Carabineros. Quite quickly, a key role in the new system of government passed to Pinochet. The military regime abolished democratic institutions, dissolved Congress, restricted civil liberties, and banned political parties. Power effectively passed to the military, which governed the country through decrees and military orders.
Thus began a period of dictatorship that lasted until 1990. Pinochet remained the regime’s leading figure for nearly 17 years. During this time, Chile endured widespread political repression, censorship, persecution of the opposition, and serious human rights violations.
What Happened During the Dictatorship
After the coup, the military began mass arrests of people they considered supporters of the Allende government or opponents of the new regime. People were detained simply for their political views, participation in labor unions, or ties to left-wing parties. Some of those detained were held in stadiums, prisons, and other makeshift detention centers. During the dictatorship, there were documented cases of torture, executions, enforced disappearances, and abductions. Many Chileans were forced to leave the country and seek refuge abroad. Today, official Chilean institutions explicitly link the period following the coup to widespread human rights violations and political repression.
The repression affected more than just politicians. Among the victims were students, journalists, labor union activists, state-owned enterprise employees, farmers, and ordinary people. The Chilean government has noted that particularly brutal repression also took place in rural areas following the coup. The consequences of this period are still felt in Chile today. Some families are still searching for information about missing relatives, and the issues of punishing those responsible and establishing the full truth remain an important part of public discourse.
Why September 11 Became a Day of Remembrance
Gradually, September 11 came to symbolize for many Chileans not the military coup itself, but its human consequences. The focus has shifted to those who were killed, went missing, were arrested, or suffered repression. That is why modern commemorative events often emphasize democracy, human rights, and the need to prevent such events from happening again.
Chilean authorities maintain that remembering the past is necessary to protect democracy in the future. In 2023, on the 50th anniversary of the coup, the government launched a large-scale state program under the slogan “Democracy Is Memory and the Future.” As part of this program, exhibitions, discussions, cultural events, and projects dedicated to the history of the dictatorship and human rights were held. Therefore, in modern-day Chile, September 11 is first and foremost a day of remembrance and reflection on what happened to the country after 1973. The government emphasizes the need to preserve historical documents, eyewitness accounts, and the memory of the victims.
How Chile Marks This Date
There is no single tradition for celebrating September 11. Instead, the day is marked by commemorative ceremonies, memorial events, exhibitions, lectures, film screenings, and meetings with relatives of the dictatorship’s victims. One of the main venues for such events is the La Moneda Presidential Palace. It was here in 1973 that the final battle around the government building took place and Salvador Allende was killed. In 2024, President Gabriel Borich held an official ceremony at La Moneda to mark the 51st anniversary of the coup. During the event, the national anthem was played, a moment of silence was observed, and the victims of the dictatorship were honored.
Separate events are held at memorial museums and former detention sites. There, organizers host exhibitions, public discussions, artistic events, and screenings of archival materials. For example, the Museum of Memory and Human Rights held special programs that reconstructed the chronology of events on September 11, 1973, using archival radio recordings. Various cities also host flower-laying ceremonies, moments of silence, marches, and cultural events. Some organizations light candles in memory of the victims. There are also more modern formats—podcasts, public discussions, documentary films, and digital archives.
Is September 11 a controversial date?
Yes. Chilean society still does not have a completely unified view of the events of 1973. For many people, September 11 is the day when democracy was destroyed and a period of severe repression began. At the same time, some Chileans still have differing views on the political situation that preceded the coup and the military’s role in it. But there is an important distinction between the discussion of the causes of the political crisis and the assessment of human rights violations following the seizure of power. Chile’s current government institutions emphasize the facts of repression, enforced disappearances, torture, executions, and other crimes committed during the dictatorship.
For this reason, September 11 remains an emotionally charged date. On this day, official memorial ceremonies, public events, and political demonstrations may all take place simultaneously across the country. For some, it is first and foremost a day of mourning for loved ones; for others, it is a reminder of the value of democracy and the need to defend human rights.

In its wake, thousands of Chileans were forced into exile, and international organizations and foreign governments actively responded to the human rights situation.
Why This Day Is Still Remembered Today
More than half a century has passed, but September 11 remains an important date for Chile. The reason is simple—the consequences of the coup did not disappear with the end of the dictatorship. The country is still home to the families of those killed and missing, people who survived imprisonment and torture, and the descendants of those who were forced to leave their homeland. That is why the memory of 1973 in Chile is linked not only to the past but also to the present. The government is opening archives, supporting museums and memorial sites, holding official ceremonies, and emphasizing the importance of human rights. The National Archives of Chile, in particular, is researching documents related to the coup and the repression to make these materials more accessible to the public.
For many Chileans, September 11 serves as a reminder of how quickly a political crisis can escalate into violent conflict. That is why, during contemporary commemorative events, calls to defend democratic institutions and resolve political conflicts without violence are becoming increasingly common. The Chilean government has repeatedly emphasized the principles of “truth, justice, and non-repetition.” This stance means that remembering the victims is not about dwelling on the past, but about ensuring that such events do not happen again in the future.
That is why September 11 is not just a date on the calendar for Chile. It is a day when the country recalls the moment that changed its political system for decades, honors the victims of the dictatorship, and reaffirms the value of democracy.
