Grandmothers of the Plaza de Mayo

The Grandmothers of the Plaza de Mayo, formally Asociación Civil Abuelas de Plaza de Mayo, is an Argentine human-rights organization created in 1977 during the military dictatorship known as the National Reorganization Process. Its central mission is to locate children who were abducted during the state repression of 1976–1983, or born to detained pregnant women whose subsequent fate was concealed, and to establish their biological identities and family histories. The organization emerged from the wider movement of relatives who gathered in Buenos Aires’s Plaza de Mayo to demand information about people who had disappeared. The grandmothers separated their work from that of the Mothers of the Plaza de Mayo because their specific concern was the fate of missing grandchildren and the systematic concealment of children’s identities. The organization argues that the disappearance of children was not merely an accidental consequence of political violence. Babies and young children were transferred to military families, regime allies, orphanages, or other households, frequently through falsified birth records and unlawful adoptions. Some mothers gave birth in clandestine detention centers before being killed or disappeared. The practice was connected to the dictatorship’s effort to prevent the children of people labeled subversive from being raised by their biological families. The Grandmothers combined investigations, court proceedings, public demonstrations, archival work, genetic research, and public education. Their efforts helped stimulate the development of forensic anthropology in Argentina and contributed to the creation of the National Genetic Data Bank, which preserves genetic information from relatives of disappeared people. With assistance from geneticists including Mary-Claire King, genetic comparison became a central method for establishing kinship, with reported probabilities of relationship approaching 99.99 percent in appropriate cases. The organization has also challenged unlawful adoptions and sought legal recognition of the right to identity. As the people being sought reached adulthood in the 1990s, the organization adjusted its methods. It increasingly used public-awareness campaigns, cultural projects, media appearances, educational programs, and confidential channels through which possible grandchildren could investigate their own backgrounds. It also developed legal counseling, investigative assistance, psychological support, volunteer training, and archival initiatives. These activities recognize that identity recovery can be emotionally difficult and that some identified individuals may resist or delay contact with biological relatives. The organization’s work has produced a lasting impact on Argentine law, memory politics, genetics, and international human-rights practice. The organization reported or was credited with identifying 133 grandchildren by July 2023, although the total number of children abducted or born in captivity is commonly estimated at about 500. Its president is Estela Barnes de Carlotto, one of Argentina’s best-known human-rights advocates. The Grandmothers continue to search for people who may not know that they were adopted and to preserve evidence for future investigations.

The Grandmothers of the Plaza de Mayo was formed in 1977 amid Argentina’s military dictatorship, which began in 1976 and used abduction, clandestine detention, torture, and disappearance against people regarded as political opponents or potential opponents. Relatives of the disappeared initially gathered in the Plaza de Mayo, in front of the seat of government, to demand answers. A group of grandmothers developed a distinct mission: locating grandchildren who had been taken from their parents or born during the detention of pregnant women. The organization’s investigations indicated that the appropriation of children was linked to a systematic policy. Pregnant detainees were sometimes kept alive until delivery, after which their babies were transferred to military personnel, regime supporters, or other families. Birth registrations and adoption documents could be falsified, while the children’s biological parents were killed or remained disappeared. The practice deprived the children of their names, medical histories, and family relationships, while also serving the dictatorship’s ideological objective of preventing them from being raised by families associated with political dissent. During the dictatorship, the grandmothers relied on personal investigations, anonymous information, interviews, and contacts with officials and foreign organizations. After constitutional government was restored in 1983 under President Raúl Alfonsín, they were able to pursue cases more openly through the courts. Early efforts were often obstructed by incomplete records, forged documents, intimidation, and the difficulty of proving biological relationships without modern genetic tools. Scientific collaboration transformed the organization’s work. Geneticists, including Mary-Claire King, helped establish methods for comparing a child’s genetic profile with samples from extended biological relatives when the parents were missing or dead. These methods supported the National Genetic Data Bank, which stores biological information from families searching for disappeared relatives. The organization’s advocacy also contributed to the growth of the Argentine Forensic Anthropology Team and to broader recognition that identity is a human right rather than only a private family matter. The organization pursued the annulment of unlawful adoptions and sought judicial orders for genetic testing. In some cases, identified children were returned to biological relatives; in others, biological and adoptive families developed continuing relationships. Not every case produced a simple reunification. Some people identified as missing grandchildren resisted contact, questioned the evidence, or faced emotional and family pressures. As the missing children became adults, ordinary custody proceedings became less relevant, and the organization shifted toward confidential outreach and public education. From the 1990s onward, the Grandmothers used advertising, television, theater, popular culture, school programs, demonstrations, and media coverage to reach adults who might not know that they had been adopted. It also offered legal guidance, investigative support, psychological assistance, and training for volunteers. An identity archive established in collaboration with the Identity Archive preserved photographs, letters, recordings, diaries, objects, and family testimony so that evidence and personal histories would remain available even after older relatives died. The organization’s work has been closely connected with major Argentine legal and historical debates about accountability for dictatorship-era crimes. Investigations arising from cases such as that of Silvia Quintela contributed to proceedings against former officials, including Jorge Rafael Videla. In 2012 Videla received a 50-year sentence for the systematic theft of babies. The Grandmothers also gained international recognition, including the Félix Houphouët-Boigny Peace Prize in 2011. Their continuing search has made them a prominent symbol of nonviolent human-rights activism and of the struggle against enforced disappearance. By July 2023, their work had led to the identification of 133 grandchildren, while the estimated number of children abducted or born in detention remained approximately 500.

  Move from custody litigation toward public outreachStrategy

  Background

  By the 1990s, many missing grandchildren were legal adults, so traditional custody proceedings no longer provided an adequate framework for identity recovery.

  Action taken

  The Grandmothers expanded media campaigns, cultural outreach, confidential counseling, and educational work aimed directly at possible adult grandchildren.

  Aftermath

  The organization continued pursuing legal cases while giving adults a route to investigate their origins and make informed decisions about family contact.
