Rafael Cancel Miranda

Rafael Cancel Miranda was born on 18 November 1930 in Mayagüez, Puerto Rico — the same western coastal city that produced Irving Flores Rodríguez, his co-conspirator in the 1954 Capitol attack — and he grew up to become not only one of four Puerto Rican Nationalists who executed the most audacious armed action of the modern independence movement, but the member of that group who most fully transformed his imprisonment, his release, and his post-prison decades into a sustained, vocal, and politically consequential public career in the service of the independence cause. He joined the Puerto Rican Nationalist Party under the influence of Pedro Albizu Campos, served briefly in the US Army before being discharged — a service that deepened rather than diminished his conviction that Puerto Rico's relationship to the United States was a form of colonialism that Puerto Ricans were being conscripted to defend rather than resist — and on 1 March 1954 entered the visitors' gallery of the United States House of Representatives with Lolita Lebrón, Irving Flores Rodríguez, and Andrés Figueroa Cordero and opened fire from the gallery onto the House floor below, wounding five congressmen in an action that was designed to announce to the world, at the moment of the Inter-American Conference in Caracas, that the Puerto Rican independence cause was alive and prepared to act on its convictions. He was arrested, tried, convicted, and sentenced to federal prison, where he would serve twenty-five years — until President Carter's September 1979 clemency freed him alongside Lebrón and Flores. He returned to Puerto Rico and did not retreat into private life: he became one of the most active and most visible public figures of the independence movement, campaigning persistently for the liberation of Puerto Rican political prisoners, speaking at rallies and conferences, opposing the US Navy's presence in Vieques, opposing US military bases across Puerto Rico, and maintaining the argument for independence with a consistency and a directness that made him one of the movement's most important voices from his return in 1979 until his death on 18 February 2020, at the age of eighty-nine. He outlived Lolita Lebrón by nearly a decade and Irving Flores Rodríguez by more than a quarter-century. He outlived by fifty-five years the event that had defined his public life. And he died having given ninety years of engagement — personal sacrifice, imprisonment, and sustained advocacy — to the cause of Puerto Rican independence without seeing it formally achieved, and without, as far as anyone could tell, ever doubting for a moment that it was right.

At a Glance

Full NameRafael Cancel Miranda; born 18 November 1930 in Mayagüez, Puerto Rico; joined the Puerto Rican Nationalist Party; served briefly in the US Army before being discharged; participated in the 1 March 1954 attack on the US House of Representatives alongside Lolita Lebrón, Irving Flores, and Andrés Figueroa Cordero; convicted and sentenced to federal prison; served twenty-five years; freed by Carter's clemency September 1979; returned to Puerto Rico and remained active in the independence movement until his death on 18 February 2020
Born18 November 1930, Mayagüez, Puerto Rico; born in the same western coastal city as Irving Flores Rodríguez, his future co-conspirator; grew up during the period of the Nationalist Party's most intense activity under Albizu Campos; his service in the US Army — from which he was discharged — deepened rather than diminished his conviction that Puerto Rico's relationship to the United States was a colonial one, and that being conscripted to serve the colonial power while Puerto Rico remained a colony was itself a form of the injustice he was committed to opposing
Died18 February 2020, San Juan, Puerto Rico; died at eighty-nine, having outlived Lolita Lebrón by almost a decade and outlived the 1954 Capitol attack by sixty-six years; he was the last surviving participant in the attack and the last living member of the group of four who had entered the House gallery on 1 March 1954; his death was mourned across Puerto Rico and in the diaspora as the passing of the most consistently active public figure of the independence movement's armed tradition
The 1954 AttackOne of four Puerto Rican Nationalists who on 1 March 1954 entered the visitors' gallery of the US House of Representatives and opened fire on the floor below, wounding five congressmen; Cancel Miranda was one of the shooters; all four were immediately arrested; the attack was timed to coincide with the Inter-American Conference in Caracas and was designed to bring international attention to the Puerto Rican independence cause at a moment of maximum hemispheric visibility; his participation was complete and his sentence was equal to those of his co-defendants
Twenty-Five YearsConvicted and sentenced to federal prison; served approximately twenty-five years; maintained throughout his imprisonment the political convictions that had produced the Capitol attack without recantation; the sustained international campaign for his release alongside Lebrón and Flores eventually produced Carter's 1979 clemency; the quarter-century of imprisonment was the price his participation cost him, and he consistently maintained in subsequent years that the cause for which he had paid that price was right and that he would pay it again
Post-Prison ActivismReturned to Puerto Rico after his 1979 release and became one of the most active and most visible public figures of the independence movement; campaigned persistently for the liberation of Puerto Rican political prisoners including those convicted of FALN and Macheteros actions in the 1970s and 1980s; spoke at independence movement events across Puerto Rico and in the diaspora; opposed the US Navy's presence in Vieques and supported the campaign for the Navy's withdrawal; maintained his public advocacy until near the end of his life at eighty-nine
Vieques and Military OppositionWas one of the most prominent voices in the movement to end the US Navy's use of the inhabited island of Vieques as a live-fire bombing range — a campaign that became one of the most broadly supported political movements in Puerto Rican history and that eventually succeeded in forcing the Navy's withdrawal in 2003; his participation in the Vieques campaign connected the armed independence tradition he represented to the broader Puerto Rican civil society movement that had developed around the environmental and health consequences of the Navy's presence on the island
Longevity and ContinuityThe forty-one years between his 1979 release and his 2020 death were years of sustained public engagement with the independence cause that distinguished his post-prison career from those of his co-defendants; Lebrón was active after her release but died in 2010; Flores lived quietly and died in 1994; Cancel Miranda maintained the highest and most consistent public profile of the three, giving him a specific historical significance as the living link between the 1954 action and the contemporary independence movement across a span of more than forty years

Mayagüez, Military Service, and the Making of a Nationalist

Rafael Cancel Miranda grew up in Mayagüez in the political atmosphere of the Nationalist Party's most intense decade — the 1940s, when Albizu Campos's movement was at its most confrontational and when the specific events of those years — the 1936 prosecution, the 1937 Ponce Massacre, the wartime political pressures on the independence movement — were shaping the political consciousness of the generation that would eventually carry out the 1950 and 1954 actions. His formation as a Nationalist was shaped by the same currents that produced his co-defendants: the jibaro tradition's fierce sense of Puerto Rican identity, Albizu Campos's uncompromising analysis of Puerto Rico's colonial situation, and the accumulated grievances of a community that had watched the American colonial administration use every available instrument — economic, legal, and military — to suppress the independence cause.

His brief military service in the US Army and his subsequent discharge added a specific dimension to his political formation that he later described as a deepening of his conviction rather than an interruption of it. Being drafted into the service of a colonial power while that power simultaneously denied the political rights of the people being drafted — conscripting Puerto Ricans to defend American democracy while maintaining Puerto Rico as a territory whose inhabitants had no voting representation in the government that was sending them to war — was not an experience that produced patriotic identification with the United States. It was an experience that made the colonial relationship's specific character visible in the most personal way available: the colonial subject's body deployed in the service of the colonial power that was denying him the right to determine his own political future.

His discharge from the Army returned him to Puerto Rico and to the Nationalist movement at the moment when the movement was preparing for the actions of 1950 and 1954. He became active in the party's networks, developed the connections with Lebrón and the other future Capitol attackers that would eventually produce the 1954 action, and committed himself with the totality that the movement's culture required to the cause that was consuming the lives of everyone around him.

The Capitol Attack and Its Forty-One-Year Aftermath

Cancel Miranda's participation in the 1954 Capitol attack was, in its immediate dimensions, indistinguishable from that of his three co-defendants: he entered the gallery, he fired his weapon, he was arrested. The sentence he received was equal to those imposed on Lebrón and Flores. The twenty-five years he served were the same in duration, if not in institution or in the specific texture of daily experience. What distinguished him from the others was what he did with the life the Carter clemency restored — the forty-one years of sustained, consistent, vocal public advocacy that he built from his 1979 release to his death in 2020.

He returned to Puerto Rico determined to maintain the public engagement with the independence cause that his imprisonment had interrupted. He spoke at movement events, gave interviews to journalists and scholars, participated in campaigns against American military presence in Puerto Rico, and maintained the argument for independence — the same argument that had produced the Capitol attack — with a directness and a consistency that made him one of the movement's most important public voices for four decades. He was not merely a historical figure appearing at commemorative events; he was an active participant in the contemporary independence movement's campaigns, bringing to them both the moral authority of someone who had paid the maximum price for his convictions and the specific political intelligence of a man who had been thinking about the independence cause for his entire adult life.

The campaign for the liberation of Puerto Rican political prisoners was one of his most sustained commitments after his release. He understood the prisoners convicted of FALN and Macheteros actions in the 1970s and 1980s — Victor Gerena, Oscar López Rivera, and others — as continuing the same tradition that had produced the 1954 action, and he argued for their release with the moral authority of a man who had himself been a political prisoner for twenty-five years. His advocacy for López Rivera was particularly sustained, and he was part of the movement that eventually succeeded in securing López Rivera's release in 2017 — more than thirty-five years after his arrest.

Vieques, the US Military, and the Continuation of the Anti-Colonial Argument

The campaign to remove the US Navy from Vieques — the inhabited island off Puerto Rico's eastern coast that the Navy had used as a live-fire bombing range for decades — was the most broadly supported political movement in Puerto Rican history during the late 1990s and early 2000s, drawing together independence activists, environmentalists, health advocates, the Catholic Church, and mainstream political figures from both major parties. Cancel Miranda was among the most prominent voices in this campaign, connecting the anti-military dimension of the independence argument to the specific environmental and public health grievances that made the Vieques question a mass political issue rather than a concern limited to the independence movement.

His ability to make this connection — between the independence tradition's fundamental argument that Puerto Rico's relationship to the United States was a form of military occupation and the specific, contemporary grievance of a community being poisoned by military exercises — was one of the most important contributions he made to the Puerto Rican political landscape in his post-prison years. He was not merely repeating the arguments of the 1950s in updated language; he was demonstrating that those arguments remained relevant to the most urgent contemporary issues facing Puerto Rican communities.

The Navy's withdrawal from Vieques in 2003 was a significant victory for the movement he had supported, and his role in achieving it was part of the reason that the post-prison phase of his career was more politically consequential than a simple assessment of his age and health might have predicted. He was not a relic of a historical tradition; he was an active participant in a living political movement, and the forty years of his post-prison public life were years of genuine political work rather than merely symbolic presence.

The Last Living Member: Sixty-Six Years After the Gallery

When Lolita Lebrón died in August 2010, Rafael Cancel Miranda became the last surviving participant in the 1954 Capitol attack. He bore this distinction with the same combination of personal dignity and political clarity that had characterised his entire public career — neither dramatising it excessively nor treating it as irrelevant, but understanding it as a specific kind of responsibility: the responsibility of the last witness, the last living connection between an event that had defined a generation of the independence movement and the contemporary movement that had grown from that tradition.

He continued to speak, to campaign, and to advocate in the years after Lebrón's death, maintaining the public presence that had distinguished him throughout the post-prison decades and adding to it the specific authority of someone who had outlived all of his companions and who therefore carried a unique historical weight. He was interviewed about the 1954 attack many dozens of times over the years, and his accounts of what had happened and why — specific, honest, and entirely unapologetic — were among the most important primary source materials available for the historical understanding of the event and of the movement that had produced it.

He died on 18 February 2020, in San Juan, at the age of eighty-nine — sixty-six years after the event that had defined his public life, forty-one years after the imprisonment that event had cost him was ended by Carter's clemency, and an indeterminate number of years before the independence cause he had served since his youth would achieve its formal goal, if it ever did. Puerto Rico mourned him as the last survivor, the last witness, the last living link to the moment when four Puerto Ricans stood up in the visitors' gallery of the House of Representatives and fired their weapons at the floor below, and said, in the most direct way available to them, that Puerto Rico wanted to be free.
