Bolivia, 1973 — dissident coup conspiracy

Bolivia (BOL)South America, AmericasAugust 18, 1973

Event Summary

This entry is coded 18 August 1973, during the military dictatorship of General Hugo Banzer in Bolivia, two years to the day after Banzer had launched his own coup against Juan Jose Torres on 18 August 1971. Banzer ruled with a repressive regime, known as the Banzerato, that banned left-leaning parties, suspended the trade union confederation, closed the universities, and relied on a coalition with the MNR and the Bolivian Socialist Falange. His rule was marked by recurring internal plots and purges, including against former allies: his first Interior Minister and co-conspirator in the 1971 coup, Colonel Andres Selich, was accused of plotting to overthrow Banzer and died of blows sustained in custody in 1973.

Banzer would drop all pretense of elections after a 1974 military revolt in Santa Cruz. The August 1973 coding sits in this period of conspiracy and counter-conspiracy within Banzer's authoritarian regime.

Editorial Note

No discrete plot is precisely dated 18 Aug 1973 in the sources located this session; the coding (the second anniversary of Banzer's own coup) sits in the Banzerato period of internal plotting and purges, exemplified by the Selich affair that ended in his death in custody in 1973. Context with strong framing. Second of two Bolivia entries in this batch; distinct from the 26 Apr 1971 anti-Torres entry.

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.
