Sandinista National Liberation Front

• 1. Introduction

  ›

  The Sandinista National Liberation Front, known by its Spanish initials FSLN, is a political force whose name reaches back to a man killed in 1934. Augusto César Sandino was a Nicaraguan nationalist who spent years fighting against the United States occupation of his country. His assassination by the US-equipped National Guard planted a grievance that would not be extinguished for four decades. When a new generation of Nicaraguan revolutionaries finally gave themselves a name in the early 1960s, they chose his. The FSLN would go on to topple a dynasty, govern a country in crisis, and survive military pressure from the most powerful nation on earth. But the questions worth asking about the Sandinistas are not simply about what they did to win power. They are about what that power looked like once held, who kept it, and what happened to a revolution that had promised something different.

• 2. Sandino and the Somoza Shadow

  ›

  Augusto César Sandino was born in 1895 and died on the 21st of February 1934, murdered by the Nicaraguan National Guard on the orders of Anastasio Somoza Garcia. The Guard was a force the United States had created and equipped. Its commander, Somoza, used Sandino's death as the first step toward the presidency he claimed in 1936, launching a family dynasty that would rule Nicaragua for more than four decades. The Somoza family's hold on the country was underwritten by Washington, and that relationship defined the grievance that the FSLN would eventually organize around. Sandino himself had led a guerrilla resistance against US military occupation from roughly 1922 until the withdrawal of the last American soldier on the 1st of January 1933. His removal from the scene did not remove the occupation's legacy. When leftist ideas began spreading through Latin America in the late 1950s and early 1960s, they landed on ground that had been prepared by decades of resentment. The poet Rigoberto Lopez Perez assassinated Anastasio Somoza Garcia in 1956, and three years later the Cuban Revolution offered a living example of what armed resistance could accomplish. In 1957, Carlos Fonseca Amador, Silvio Mayorga, Tomás Borge, and others formed the first cell of what would become the FSLN. The suffix "-ista" in "Sandinista" is simply the Spanish equivalent of "-ist": a follower, an adherent, someone who carries forward a tradition. The term would not be formally adopted until two years after the FSLN's founding, but the link to Sandino's struggle was always the ideological anchor.

• 3. Founding in Fragmentation

  ›

  Carlos Fonseca and Tomás Borge were among the founders who gathered, reportedly in Tegucigalpa, Honduras, in 1961 to establish what they first called the National Liberation Front. The supposed founding date of the 19th of July 1961 has been cited repeatedly, though the source acknowledges no documentary evidence supports the meeting at all; the claim only surfaced after the revolutionary victory of 1979. Of the original founders, only Borge lived to see the Sandinista triumph. The early years were not orderly. As late as 1963, internal coherence was lacking; even the group's newspaper, Trinchera, reflected unresolved political disagreements. The FSLN drew students from the University of León and the National Autonomous University of Nicaragua in Managua, and its activity in the late 1950s and early 1960s included guerrilla attempts that repeatedly ended in defeat. A key episode known as "El Chaparral" in June 1959 saw a guerrilla unit under Rafael Somarriba, which included Fonseca, hunted down and destroyed by the Honduran Army acting in coordination with Nicaraguan National Guard intelligence. More deaths followed in subsequent months and in the events of "El Dorado" on the 28th of February 1960. The movement's first programmatic document was not published until 1969. By the early 1970s, military action remained limited. It was not a unified or coherent organization so much as a collection of shared convictions: distrust of the established left, commitment to armed struggle, and a felt connection to Sandino's example.

• 4. Three Factions, One Earthquake

  ›

  On the 23rd of December 1972, a magnitude 6.2 earthquake leveled Managua. Ten thousand of the city's 400,000 residents died. Another 50,000 were left without homes, and roughly 80 percent of the city's commercial buildings were destroyed. What followed radicalized the opposition: President Anastasio Somoza Debayle's National Guard embezzled large portions of the international reconstruction aid, and Somoza distributed contracts to family and friends, with estimates placing his personal wealth at US$400 million by 1974. The earthquake exposed the regime's corruption in a way that abstract political argument could not. Within this environment, the FSLN had splintered into three distinct factions. The GPP, or "Prolonged Popular War" faction, favored slow accumulation of support in the rural north. The Proletarian Tendency, led by Jaime Wheelock, applied an orthodox Marxist framework and focused on organizing urban workers. The Terceristas, led by Daniel Ortega, his brother Humberto Ortega, and Victor Tirado Lopez, were more pragmatic: they favored rapid insurrection and tactical alliances with non-communist opponents of Somoza, including business figures and the conservative right. In December 1974, a Tercerista-aligned guerrilla group directed by Eduardo Contreras and Germán Pomares seized hostages at a party in the Managua suburb Los Robles, killing the minister who tried to resist them and extracting US$2 million in ransom, along with the release of political prisoners over the following year. One of those prisoners was Daniel Ortega. The government's response was intensified repression, and by 1975 Somoza had imposed a state of siege. Carlos Fonseca, who had returned from exile in Cuba in 1975 to try to reunite the factions, was ambushed, wounded, and executed by the National Guard the following year, 1976.

• 5. Revolution and Its Cost

  ›

  The September Insurrection of 1978 marked a turning point. Twenty-three Tercerista commandos led by Edén Pastora seized the entire Nicaraguan congress, taking nearly 1,000 hostages including Somoza's nephew and cousin. Somoza paid a $500,000 ransom and released 59 political prisoners. Days later, six cities rose in revolt. The uprising was subdued at the cost of several thousand lives, most of them civilian, but it blurred the lines between factions and pushed toward reunification. On the 7th of March 1979, nine men representing the three tendencies formally reconstituted a unified National Directorate. By mid-April, five guerrilla fronts operated under joint FSLN command. On the 4th of June, the FSLN called a general strike. On the 17th of July, Somoza resigned and fled to Miami. His successor, Francisco Urcuyo, lasted two days before ceding power and fleeing to Guatemala. On the 19th of July 1979, the FSLN army entered Managua. The war left between 30,000 and 50,000 dead and forced 150,000 Nicaraguans into exile. The new government inherited a debt of US$1.6 billion, 600,000 homeless, and a devastated economy. The five-member Junta of National Reconstruction included Daniel Ortega, novelist Sergio Ramírez, and Violeta Barrios de Chamorro, widow of assassinated newspaper editor Pedro Joaquín Chamorro. Within six months, the FSLN's literacy campaign had taught half a million people to read, reducing the national illiteracy rate from over 50 percent to just under 12 percent. UNESCO recognized the campaign with a Nadezhda Krupskaya International Prize. The Council of State's structure, however, reserved only 12 of 47 seats for political parties, and of those 12, only 3 were not aligned with the FSLN. By 1980, both non-Sandinista junta members had resigned.

• 6. The Contra War

  ›

  Upon taking office in 1981, US President Ronald Reagan condemned the FSLN for what he characterized as support for Marxist movements elsewhere in Latin America. The CIA was authorized to finance, arm, and train anti-Sandinista rebels, most of them remnants of Somoza's National Guard, known as the Contras. A separate Contra force was led by Edén Pastora, the same commander who had seized the Nicaraguan congress in 1978 and who had since broken with the FSLN. The Contras conducted economic sabotage, attacked schools and health centers, and mined Nicaragua's Corinto harbour, an action the International Court of Justice ruled illegal. In 1984, the International Court of Justice also ruled that US support for the Contras violated international law. After the US Congress prohibited federal funding of the Contras through the Boland Amendment in 1983, the Reagan administration arranged the covert sale of arms to Iran and channeled the proceeds to the Contras; this became the Iran-Contra affair. National Security Council aide Lieutenant Colonel Oliver North took much of the resulting blame. Senator John Kerry's 1988 committee report found that senior US policy makers were not immune to treating drug money as a funding solution for the Contras, and the National Security Archive documented contact between Oliver North and Manuel Noriega, the US-backed president of Panama. Throughout the Contra war, the Sandinistas arrested suspected opponents and censored publications. A State of Emergency declared in March 1982 suspended civil liberties including habeas corpus, freedom of the press, and freedom of assembly; it lasted six years, until January 1988. Sandinista censor Nelba Cecilia Blandón ordered all radio stations to broadcast from the government station La Voz de La Defensa de La Patria every six hours, and twenty-four independent programs were cancelled in total.

• 7. Elections, Loss, and Return

  ›

  In 1984, Nicaragua held national elections that independent observers from the United Nations and Western Europe declared fair. Daniel Ortega and Sergio Ramírez were elected president and vice-president, with the FSLN winning 61 of 96 seats in the National Assembly and 67 percent of the vote on a 75 percent turnout. The United States refused to recognize the result. The 1990 election, mandated by the constitution passed in 1987, unfolded in a different context. The Bush administration had channeled $49.75 million in aid to the Contras and $9 million to the opposition UNO coalition, an amount the source describes as equivalent, proportionately, to five times what George Bush had spent on his own presidential campaign. On the 25th of February 1990, Violeta Barrios de Chamorro received 55 percent of the popular vote against Daniel Ortega's 41 percent. A post-election survey found that 75.6 percent of respondents agreed the Contra war would never have ended had the Sandinistas won. After their defeat, Sandinista leaders retained much of the private property that had been nationalized during their rule, a process known as the "piñata". Internal fractures followed: Ernesto Cardenal and Sergio Ramírez both resigned from the party, and Ramírez founded the Sandinista Renovation Movement, whose supporters became known as renovistas in contrast to the ortodoxos loyal to Ortega. In 1996, Ortega received 43 percent of the presidential vote, losing to Arnoldo Alemán's 51 percent. He lost again in 2001 to Enrique Bolaños, 46.3 percent to 53.6 percent. In 2006, Ortega was reelected president with 38 percent of the vote, returning the FSLN to government. In October 2009, a Supreme Court with a Sandinista majority overturned the constitutional term limits that had prevented Ortega from standing again. Ortega and the FSLN were reelected in 2011, 2016, and 2021, though international observers denounced all three elections. On the 29th of January 2019, the Socialist International expelled the FSLN, citing gross violations of human rights and democratic values.

• 8. Faith, Ideology, and the Sandino Symbol

  ›

  Catholic priest Ernesto Cardenal, who served as the Sandinista Minister of Culture, put it plainly: "I think Nicaraguans who separate Christianity from Revolution are mistaken. Here they are the same thing." This fusion was not incidental. The FSLN, lacking conventional party structures, relied on friendly clergymen to build its organizational base. According to researcher Peter Marchetti, the relationship grew so close that "the parish replaced Lenin's idea of a cell." Sandinista musician Carlos Mejía Godoy composed a piece called "Misa Campesina Nicaraguense," a Nicaraguan peasant mass that replaced traditional liturgical music in Nicaraguan churches, with hymns praising what the source describes as "worker Christ." The FSLN distributed paintings depicting Christ's resurrection, with Christ shown wearing a black and red cape bearing the letters FSLN. Ideologically, the movement contained genuine tensions. The GPP faction was rural-based and Maoist in orientation. The Proletarian Tendency, led by Wheelock, drew on orthodox Marxism. The Terceristas were pragmatic and eclectic, willing to partner with business owners, churches, and the middle class. What held these together was the figure of Sandino, whom the Secretary-General Carlos Fonseca described as the channel through which he lived his Christian faith more authentically. Sandinismo also drew on what the source describes as "liberation theology," the Latin American theological current that frames Christian obligation in terms of justice for the poor. Tomás Borge argued the revolution was "on behalf of all human beings, but as with Christ above all for the poor." KGB records from the Mitrokhin Archive, processed by Cambridge historian Christopher Andrew, indicate that Fonseca had been recruited by the KGB in 1959 during a trip to Moscow, and that by 1960 the KGB had organized funding and training for twelve individuals Fonseca handpicked as the core of the new organization. The Sandinista cultural apparatus was built, in other words, from overlapping and sometimes contradictory sources of inspiration, with Sandino's image at the center binding them all.
