The military governments that took power in Chile in September 1973 and Argentina in March 1976 combined mass detention and enforced disappearance with the expulsion and flight of political opponents on a scale that emptied universities, unions and parties. Chile's Rettig Commission investigated killings and disappearances and its successor, the Valech Commission, took testimony from 35,868 people between 2003 and 2005, recognising 27,255 cases of political imprisonment and torture and adding 1,204 more in a complementary report, with about two-thirds of recognised abuses occurring in 1973 alone. Argentina's CONADEP documented 8,960 disappearances for 1976-83 and concluded that disappearance, torture, secret detention and clandestine disposal of bodies were systematic practices ordered from the top; its report Nunca Más noted that estimates of the true total ranged from 10,000 to 30,000. The two governments cooperated with Uruguay, Paraguay, Bolivia and Brazil through Operation Condor to pursue exiles across borders. Hundreds of thousands of Chileans and Argentines went into exile in Mexico, Spain, Sweden, France, Canada and elsewhere; most exile figures come from scholarly reconstruction rather than official counts, and the flow numbers above are approximate.

Chile's population was about 10.0 million and Argentina's about 24.8 million in 1973 on UN Population Division estimates. Chile's Rettig and Valech commissions documented about 3,200 killed or disappeared and more than 38,000 tortured; Argentina's CONADEP documented 8,960 disappearances, with human rights organisations claiming up to 30,000.
The low end sums individually documented victims: about 3,200 killed or disappeared in Chile as recognised by the Rettig and Valech commissions, plus the 8,960 disappearances documented by Argentina's CONADEP. The high end reflects the 30,000 figure used by Argentine human rights organisations, which CONADEP itself noted as the upper bound of contemporary estimates, added to the Chilean total. The disagreement is driven by the destruction of military records and by unreported cases, not by dispute over whether the killings occurred.
Disappearance, torture, execution and arbitrary detention were documented by CONADEP in Argentina and the Rettig and Valech commissions in Chile; sexual violence in detention and the appropriation of babies born to disappeared women were documented by the Valech Commission and by Argentine courts prosecuting the systematic theft of infants.
