Chilean Truth and Reconciliation Commission
With the end of General Augusto Pinochet's dictatorship in 1989, newly-elected President Patricio Aylwin established Chile's National Commission for Truth and Reconciliation. The Commission was tasked with investigating lethal human rights abuses the people of Chile had suffered at the hands of the government for 25 years. The commission's report, released in 1991, was among the earliest such "truth reports" documenting atrocities against a nation's people.
Two years following the report's release, The Center for Civil and Human Rights commissioned an English-language translation of the document, immediately making both the substance and the form of the report widely available. CCHR's translation can be found here.
