The Madres de Plaza de Mayo is a group of Argentine mothers who began protesting in the late 1970s. They sought information about their children, who were forcibly disappeared during the military dictatorship from 1976 to 1983. The mothers gathered in the Plaza de Mayo in Buenos Aires, wearing white headscarves to symbolize their lost children. Over the years, the Madres became a powerful symbol of human rights activism in Argentina and worldwide. They have worked to raise awareness about the atrocities committed during the dictatorship and continue to advocate for justice and accountability for the victims of state terrorism.
