Alfredo Stroessner was a Paraguayan military officer and the country's president from 1954 to 1989. HIs rule was the 14th longest ever by state leaders.
Under Stroessner Paraguay was a leading participant in Operation Condor, a campaign of state-terror and security operations which were jointly conducted by the right-wing military governments of six Latin American countries (Chile, Argentina, Bolivia, Paraguay, Uruguay and Brazil). Human rights violations characteristic of those in other Latin American countries such as kidnapping, torture, forced disappearance and extrajudicial killing, were routine and systematic during the Stroessner regime. Following executions, many of the bodies of those killed by the regime were dumped in the Chaco or the Rio Paraguay. The discovery of the "terror archives" in 1992 in the Lambaré suburb of Asunción, confirmed allegations of widespread human rights violations.
Under Stroessner, egregious human rights violations were committed against the Ache Indian population of Paraguay's eastern districts. The Ache Indians resided on land that was coveted by foreign multinationals and had resisted relocation attempts by the Paraguayan army. The government retaliated with massacres and forced many Ache into slavery. In 1974 the UN accused Paraguay of slavery and genocide
