Question: The Mothers of Plaza de Mayo, is a 1985 Argentine documentary film, about which association of Argentine mothers whose children "disappeared" during the state terrorism of the military dictatorship, between 1976 and 1983?
Context: Alicia Domon, Caty, (born September 23, 1937, Charquemont, Doubs, France; disappeared on December 17 or 18, 1977 near Santa Teresita by the Argentine Sea) was a Roman Catholic nun from France who was one of two French nationals to be "disappeared" in December 1977 in Argentina during the military dictatorship of the "National Reorganization Process" (1976–1983).  She was among a dozen people associated with the Mothers of the Plaza de Mayo, a human rights group, who were kidnapped and taken to the secret detention center at ESMA. "Mothers of the Disappeared" is a song by Irish rock band U2.  It is the eleventh and final track on their 1987 album "The Joshua Tree".  The song was inspired by lead singer Bono's experiences in Nicaragua and El Salvador in July 1986, following U2's participation in the Conspiracy of Hope tour of benefit concerts for Amnesty International.  He learned of the Madres de Plaza de Mayo, a group of women whose children had "forcibly disappeared" at the hands of the Argentine and Chilean dictatorships.  While in Central America, he met members of COMADRES, a similar organization whose children had been abducted by the government in El Salvador.  Bono sympathized with the Madres and COMADRES and wanted to pay tribute to their cause. Renée Slotopolsky de Epelbaum (June 15, 1920 – February 7, 1998), also known as Yoyi Epelbaum, was an Argentine human rights activist.  She is known for being one of the founders of the Mothers of the Plaza de Mayo, an association of mothers of those disappeared during the military dictatorship known as National Reorganization Process that ruled Argentina between 1976 and 1983.  She was also one of the founders of the Jewish movement for Human Rights (Spanish: "Movimiento Judío por los Derechos Humanos" ). The "Dirty War" (Spanish: "Guerra Sucia" ), was the name used by the Argentine Military Government for a period of state terrorism in Argentina from roughly 1974 to 1983 (some sources date the beginning to 1969), during which military and security forces and right-wing death squads in the form of the Argentine Anticommunist Alliance (Triple A) hunted down and killed left-wing guerrillas, political dissidents, and anyone believed to be associated with socialism.  About 30,000 people disappeared, many of which were impossible to be formally reported due to the nature of the issue: state terrorism.  The targets were left-wing activists, guerrillas and militants, trade unionists, students, journalists and Marxists and Peronist guerrillas and their support network in the Montoneros believed to be 150,000-250,000-strong and 60,000-strong in the ERP, as well as alleged sympathizers.  Some 10,000 of the "disappeared" were guerrillas of the Montoneros (MPM) and the Marxist People's Revolutionary Army (ERP) although the lowest estimate is that the Montoneros and ERP had a combined strength of 5,000.  The "disappeared" included those thought to be a political or ideological threat to the military junta, even vaguely, and they were killed in an attempt by the junta to silence the opposition and break the determination of the guerrillas.  The worst repression reportedly occurred after the guerillas were largely defeated in 1977, when the church, labor unions, artists, intellectuals and university students and professors were targeted.  Although the Montoneros reported having carried out some 600 armed attacks in 1977, the guerrilla threat had greatly declined.  The junta justified this mass terror by exaggerating the guerrilla threat, and even staged attacks to be blamed on guerillas and used frozen dead bodies of guerilla fighters that had been kept in storage for this purpose.  In late 1979, Amnesty International accused the Videla military government of being responsible for the disappearance of 15,000 to 20,000 Argentine citizens since the 1976 coup.  That year, a special study by the New York City Bar concluded that around 10,000 Argentines had disappeared since the coup.  According to "Registro Unificado de Víctimas del Terrorismo de Estado" (Ruvte), 662 were disappeared under the presidency of Isabel Perón and 6,348 were disappeared during the military dictatorship. The Mothers of Plaza de Mayo (Spanish: "Las Madres de la Plaza de Mayo" ) is a 1985 Argentine documentary film directed by Susana Blaustein Muñoz and Lourdes Portillo about the Mothers of the Plaza de Mayo.  It was nominated for an Academy Award for Best Documentary Feature. Léonie Duquet (April 9, 1916, Longemaison, Doubs, France – 1977, Argentina) was a French nun who was arrested in December 1977 in Buenos Aires, Argentina and "disappeared."  She was believed killed by the military regime of Argentine President Jorge Rafael Videla during the Dirty War.  Alice Domon, a French nun working with Duquet, disappeared a few days later.  They had been working in poor neighborhoods of Buenos Aires in the 1970s and supported the Mothers of the Plaza de Mayo, founded in 1977.  Despite repeated efforts by France to trace the sisters, the Argentine military dictatorship was unresponsive. Adelina Ethel Dematti de Alaye (June 5, 1927 – May 24, 2016) was an Argentine human rights activist who co-founded the Mothers of the Plaza de Mayo, an organization of mothers whose children disappeared during the Dirty War of the 1970s and early 1980s.  She became known as "la madre fotógrafa," or "the mother photographer," for her documentation of the Argetine dictatorship and the Mothers of the Plaza de Mayo through her photography.  Her collection was later declared a "Memory of the World" by UNESCO.  In addition to her work with the Mothers of the Plaza de Mayo, Dematti was also active within the Permanent Assembly for Human Rights (APDH). The Mothers of the Plaza de Mayo (Spanish: "Asociación Madres de Plaza de Mayo" ) is an association of Argentine mothers whose children "disappeared" during the state terrorism of the military dictatorship, between 1976 and 1983.  They organized while trying to learn what had happened to their children, and began to march in 1977 at the Plaza de Mayo in Buenos Aires, in front of the Casa Rosada presidential palace, in public defiance of the government's state terrorism intended to silence all opposition. Hebe Pastor de Bonafini (born December 4, 1928) is an Argentine activist, one of the founders of the Association of the Mothers of the Plaza de Mayo, an organization of Argentine mothers whose children were disappeared during the Dirty War. María Adela Gard de Antokoletz (October 11, 1911 – July 23, 2002) was one of fourteen women who founded the Mothers of the Plaza de Mayo movement.  Her son Daniel was abducted in November 1976.  Later, when she was working for the provincial courts in Buenos Aires, she joined other mothers of missing children to found the Mothers of the Plaza de Mayo.  This group was dedicated to finding out what had happened to their missing children.  As part of this group, María Adela Gard de Antokoletz led protest marches every Thursday on Buenos Aires's Plaza de Mayo holding a picture of her son.  Throughout her life, she received death threats because of her work, but she refused to forget what had happened to her son.
