Answer:
The Mothers of the Plaza de Mayo organized in response to a surge in missing persons in Argentina.
Explanation:
The Mothers of Plaza de Mayo is an Argentine association formed during the dictatorship of Jorge Rafael Videla in order to recover the disappeared detainees alive, and then establish who was responsible for the crimes against humanity and promote their prosecution.
During the years of the Argentine military dictatorship 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.
