Gladys del Carmen Marín Millie (Spanish pronunciation: [ˈɡlaðis maˈɾin]; July 18, 1937 – March 6, 2005)[1] was a Chilean activist and political figure.

She was a staunch opponent of General Augusto Pinochet and filed the first lawsuit against him, in which she accused him of committing human rights violations during his seventeen-year dictatorship.

While in High School in Chile she began participating in organizations that aid the poor, specifically while a part of the Juventud Obrera Católica (Young Catholic Workers).

[2] In 1957, she received her teacher's diploma and joined the staff of School No 130 for students with intellectual disabilities inside the capital's main mental hospital.

During her time at the Communist Youth, she helped work on Socialist President Salvador Allende's presidential campaign and met her husband Jorge Muñoz Poutays.

In 1997, Marín ran for a seat in the Senate and obtained the eighth largest national majority, but was not elected due to the nature of the Chilean electoral system, which favours the two dominant parties or coalitions.

She ran for president in 1999 and achieved less than four percent of the vote, mainly due to fear from leftist voters that the right-wing candidate Joaquín Lavín could defeat Socialist Ricardo Lagos.

[citation needed] On January 12, 1998, Marín filed a complaint — the first person in Chile to do so — against Augusto Pinochet, accusing him of genocide, kidnapping, illicit association and illegal inhumation.

In August 2000, Marín attended the Third Al Mathaba Conference, held by the Al-Mathaba World Anti-Imperialist Centre, a centre in Libya established by Libyan leader Muammar Gaddafi for supporting anti-imperialist and leftist revolutionaries worldwide, as the representative of the PCCh, whose erstwhile anti-Pinochet armed wing, the Manuel Rodríguez Patriotic Front, had received support from Libya and its leader.

In 2002, she wrote La vida es hoy and was a contributor to 1000 Days of Revolution: Chilean Communists on the Lessons of Popular Unity 1970-73 by Kenny Coyle.
