Bolivia, 1979 — military coup attempt

Bolivia (BOL)South America, AmericasOctober 11, 1979

Event Summary

The dataset records an attempted military coup in Bolivia on 11 October 1979 during the country's chaotic and short-lived return to civilian rule, when the fragile interim government of President Walter Guevara Arze, installed by Congress in August 1979 after inconclusive elections, was surrounded by restless and faction ridden armed forces impatient to reassert control. Bolivia in this period cycled through governments at dizzying speed. A coup attempt in October 1979 came within that instability and did not immediately end civilian rule, but the reprieve was brief.

On 1 November 1979 Colonel Alberto Natusch Busch seized power in a bloody coup that overthrew Guevara, only to be forced out days later by popular and congressional resistance, after which Lidia Gueiler Tejada became interim president. That government too fell, to the brutal July 1980 cocaine coup of General Luis Garcia Meza, before Bolivia finally achieved a durable return to democracy in 1982.

Editorial Note

No discrete documentation of a coup attempt precisely on 11 October 1979 in Bolivia was found in accessible English sources this session; the entry records the dataset's coding and the verified context of the fragile Guevara interim government weeks before the 1 November 1979 Natusch coup, with the specific 11 October event unconfirmed, flagged as context only. Continues the long Bolivia run.
