Argentina, 1987 — military coup attempt

Argentina (ARG)South America, AmericasApril 17, 1987

Event Summary

In April 1987, during Holy Week, a faction of the Argentine Army known as the Carapintadas, or painted faces, for the camouflage they wore, launched an armed uprising against the democratic government of President Raul Alfonsin, in the most serious challenge to Argentina's young democracy since the fall of the military junta in 1983. The revolt, called Operation Dignity by its leaders, began on 14 to 15 April when officers linked to the Dirty War refused to appear before courts prosecuting military personnel for the disappearances and torture of the 1976 to 1983 dictatorship; Lieutenant Colonel Aldo Rico led rebels who barricaded themselves in the Campo de Mayo barracks near Buenos Aires, demanding an end to the human rights trials and the removal of the army chief. Loyal units surrounded but would not attack the rebels, yet the coup collapsed under overwhelming civilian resistance: hundreds of thousands filled the Plaza de Mayo, unions called a general strike, and every major party backed Alfonsin, who went to Campo de Mayo and secured the rebels' surrender on 17 to 19 April, emerging to tell the crowd the house was in order.

Editorial Note

Dataset date 17 April 1987 falls within the 14 to 19 April 1987 Carapintada Semana Santa revolt against Alfonsin. Dataset codes it a military coup with leader unharmed, accurate. Well documented. First Argentina record in the dataset run to reach the restored democratic era; the revolt led to the Due Obedience Law shielding lower ranking officers from prosecution.

Cross-Reference

Only one dataset carries it. One of the three reference datasets we check against carries this event; the others do not list it. That is not a contradiction — the datasets cover different periods and use different thresholds — but it means the record has had less outside corroboration.
