Chile, 1948 — dissident coup conspiracy

Chile (CHL)South America, AmericasOctober 31, 1948

Event Summary

In 1948, during the anti-communist turn of the government of President Gabriel Gonzalez Videla in Chile, the president learned of a plot by some members of the armed forces to lead a coup against him and install the former president and army general Carlos Ibanez del Campo in power. Gonzalez Videla had been elected in 1946 with communist support and had appointed three communists to his first cabinet, but under Cold War pressures and a wave of communist-led strikes he broke with the party, expelled its ministers, and on 3 July 1948 enacted the Law for the Permanent Defense of Democracy, the so-called Ley Maldita, which outlawed the Communist Party and interned leftist leaders in the Pisagua desert camp. Amid this turmoil the coded 31 October 1948 conspiracy reflects the discovered military plot to replace Gonzalez Videla with Ibanez, who had ruled Chile as a strongman in the late 1920s and would later return to the presidency by election in 1952.

The plot failed and Gonzalez Videla completed his term.

Editorial Note

Documented plot: Wikipedia states directly that Gonzalez Videla learned of an armed-forces plot to install Ibanez in 1948; the coded 31 October 1948 date falls within that anti-communist crisis year. First Chile record in the dataset 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.
