Wild timing, I just finished a chapter on the 1991 Constituent Assembly last night for a Latin America politics class I'm auditing online. Reading about an M-19 commander who actually sat down and helped write a constitution instead of just fighting over one stuck with me. Didn't expect to see his name again this fast.
Their story

Antonio José Navarro Wolff (9 July 1948 to 1 November 2026) was a Colombian sanitary engineer, former guerrilla commander and politician who became one of the defining figures of Colombia's transition from armed conflict to constitutional democracy. Born in Pasto, Nariño, he rose to second-in-command of the 19th of April Movement (M-19), helped negotiate its 1990 peace agreement with the government of Virgilio Barco, and then led the demobilised movement into electoral politics as the M-19 Democratic Alliance. In 1991 he was one of the three co-presidents of the National Constituent Assembly, alongside the Conservative Álvaro Gómez Hurtado and the Liberal Horacio Serpa Uribe, that wrote the Constitution which still governs Colombia.
Navarro was the son of Rafael Navarro Uribe and María Emma Wolff Pizarro. He graduated as a sanitary engineer from the University of Valle in Cali in 1972, taught there until 1978 and directed its sanitary engineering curriculum. On scholarships from the Rockefeller Foundation, the British Council and Canada's International Development Research Centre, he studied environmental engineering at Loughborough University in England. He coordinated the rural development research centre CIMDER and advised the IDRC before joining the M-19 at the end of the 1970s. He later said that the group's nationalist, Bolivarian message, symbolised by its theft of Simón Bolívar's sword, drew him in.
During the government of Belisario Betancur he coordinated the M-19's peace negotiating team and headed the commission organising a National Dialogue. In May 1985, as the truce collapsed, a grenade thrown in a Cali cafeteria exploded about ten centimetres from him. He was left with more than 100 pieces of shrapnel in his body, nerve damage that affected his speech and the loss of his left leg, which was amputated in Mexico before he was fitted with a prosthesis in Cuba. Months later, in November 1985, the M-19 carried out the siege of the Palace of Justice, the most controversial episode in the group's history.
Navarro returned to negotiations alongside commander Carlos Pizarro, and in March 1990 the M-19 signed peace with the Barco government. When Pizarro, the movement's presidential candidate, was assassinated aboard a commercial flight on 26 April 1990, the leadership chose to stay on the path of peace and named Navarro in his place. He finished third in the May 1990 presidential election with about 12.5 percent of the vote. President César Gaviria appointed him Minister of Health, a post he left to head the M-19 Democratic Alliance list for the Constituent Assembly, where the list became one of the largest forces and he was chosen co-president. The new Constitution was proclaimed on 4 July 1991.
His later career spanned almost every level of Colombian government. He ran again for president in 1994, served as Mayor of Pasto from 1995 to 1997 and was named best mayor in Colombia in a national award in 1998. He sat in the Chamber of Representatives for Bogotá from 1998 to 2002 and in the Senate from 2002 to 2006, when he also became a leader of the left-wing Alternative Democratic Pole and lost its presidential primary to Carlos Gaviria Díaz. As Governor of Nariño from 2008 to 2011 he became known for participatory budgeting and for pragmatic cooperation with the national government of Álvaro Uribe, who later recalled their respectful relationship despite their differences. In 2012 he briefly served as Secretary of Government to Bogotá mayor Gustavo Petro, a former M-19 comrade, before resigning. He returned to the Senate for the Green Alliance from 2014 to 2018, sought the party's Bogotá mayoral nomination in 2019 and remained one of its co-presidents into his final years.
Navarro's record was not without controversy. Cali Cartel accountant Guillermo Pallomari testified in a US court that cartel money had reached politicians around the Constituent Assembly and named Navarro among them, claims that analysts at the time considered of doubtful credibility. Questions about the M-19's alleged links to drug traffickers and its responsibility for the Palace of Justice tragedy followed him throughout his public life.
He was married to Amparo Erazo, with whom he had a son, Camilo, and later to Marcela Bustamante Morón, the mother of his sons Gabriel and Alejandro. Gabriel died in January 2015 at the age of 19. Navarro was portrayed by actor Fabio Rubiano as the character Marco Navia in the television series Escobar, el patrón del mal.
Navarro died on 1 November 2026, at 2:42 pm, at the age of 78. His family announced the death in a statement calling him "the Man of Peace" and asked for privacy, saying the farewell would be held in the intimacy of the family. The cause of death was not made public; press reports noted only that he had been in poor health. Tributes came from across the political spectrum, from Iván Cepeda and Gustavo Bolívar on the left to former president Álvaro Uribe, Sergio Fajardo and former peace negotiator Humberto de la Calle, who wrote that "much of the Constitution" was owed to him. As the last surviving member of the triumvirate that presided over the 1991 Assembly, he is remembered as the commander who signed the peace and kept his word.
