In 1977 a group of women gathered at me main square of Buenos aires. Each one of them had something in common: at least one child who had been disappeared by Argentina’s military regime. The Mothers of the Plaza de Mayo organized while trying to learn what had happened to their children and began to march looking for information on their whereabouts and to protest against human rights violations. What started as a dozen mothers looking for their children has become a symbol of nonviolent resistance against government oppression. Thirty-nine years have passed and they still march every Thursday around the Piramide de Mayo, still looking for the disappeared.
