In response to the actions of the military government in Argentina, the Mothers of the Plaza de Mayo held protests and demanded aswers.
The Mothers of the Plaza de Mayo began to meet in the plaza of the city of Buenos Aires of that name on Saturday, April 30, 1977. They used it as a binding point to organize and be able to petition the authorities for their missing children. At first they remained seated, but having declared a state of siege, the police expelled them from the place. Then, to identify themselves as a group on the pilgrimage to Lujan in October 1977, they decided to put a white handkerchief on their heads. Thus, the two symbols that represent them emerged: the marches every Thursday at three thirty in the afternoon around the Pyramid of May, and the white handkerchief on the head.
During the years of the Argentine military dictatorship (known in that country as the 'process') they were constantly opposed to the measures taken by the government, suffering constant persecution, including kidnappings and disappearances. In 1979, they stopped demonstrating in the Plaza de Mayo due to repression, but from 1980 they continued to do so. In the first days of December of that year they made the first 'march of the resistance', consisting of walking around the square for 24 hours.
In spite of the arrival of democracy in the country, in 1983, they continued with their marches and acts, asking for condemnation for the military that participated in the government. They have received support and recognition in a large number of international organizations and given their support to many other groups fighting for human rights.
