Bolivia, 1978 — dissident coup conspiracy

Bolivia (BOL)South America, AmericasOctober 29, 1978

Event Summary

This entry is coded 29 October 1978, in the final weeks of General Juan Pereda Asbun's brief and contested presidency in Bolivia, weeks before his overthrow by General David Padilla. Pereda, Hugo Banzer's handpicked candidate, had been declared winner of the July 1978 election through massive fraud, with official results showing more votes than registered voters; the National Electoral Court annulled the result on 19 July, and Pereda seized power the next day in a coup, becoming a non-constitutional president. He promised elections but set no firm date, and his regime was isolated and lacked a coherent program.

This alienated the younger institutionalist faction of the officer corps, who suspected he never intended to hold elections. On 24 November 1978 General David Padilla Arancibia overthrew Pereda in a bloodless coup and promptly set a firm date for a return to civilian rule. The October 1978 coding sits in this period of intense military plotting against the weak Pereda government in the weeks before the Padilla coup.

Editorial Note

No discrete plot is precisely dated 29 Oct 1978 in the sources located this session; the coding sits in the weeks of military plotting against the illegitimate Pereda government before the 24 November 1978 Padilla coup. Context with strong framing. This is the fourth Bolivia entry across the run and distinct from the batch-10 anti-Torres (1971) and Banzer-era (1973) entries.

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.
