After the death of the controversial President Juan Peron in 1974, his wife and vice president, Isabel Peron, assumed power. However, she was not very strong politically and a military junta led a coup against her and removed her from office. This military junta maintained its grip on power by cracking down on anybody whom they believed was challenging their authority. Casualty counts from this war range from 10,000 to 30,000 people.
