Guatemala, 1982 — dissident coup conspiracy

Guatemala (GTM)Central America, AmericasAugust 13, 1982

Event Summary

This entry is coded 13 August 1982, during General Efrain Rios Montt's consolidation of dictatorial power in Guatemala amid discontent among the officers and civilians sidelined after the March 1982 coup and among loyalists of the ousted Lucas Garcia government. The 23 March 1982 coup by young officers had installed Rios Montt as head of a three-man junta, but on 9 June 1982 he forced out the other two junta members to rule alone as head of state, commander of the armed forces, and defense minister, dashing the plotters' hopes for a civilian-military junta and prompt elections. In June 1982 Rios Montt claimed to have uncovered a coup plot by followers of ousted General Lucas Garcia and postponed elections to 1985, and he ruled by decree under martial law with a suspended constitution while intensifying a brutal counterinsurgency (Victoria 82 and Operation Sofia) against the URNG and indigenous population.

On 17 August 1982 he established a new Council of State. The 13 August 1982 coding sits in this period of plotting against Rios Montt by disillusioned officers and Lucas loyalists, days before the Council of State's creation.

Editorial Note

No discrete plot is precisely dated 13 Aug 1982 in the sources located this session; the coding sits in the period of anti-Rios Montt plotting by disillusioned officers and Lucas loyalists as he consolidated sole power, days before the 17 Aug 1982 Council of State. Context with strong framing. First Guatemala record in the run.

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.
