Bolivia, 1946 — military coup attempt

Bolivia (BOL)South America, AmericasJune 13, 1946

Event Summary

On 13 June 1946 conservative military elements attempted a revolt against President Gualberto Villarroel of Bolivia, one of a series of failed uprisings against his reformist RADEPA and MNR government that were financed largely by the big tin mining interests known as the Rosca. Villarroel, who had taken power in a December 1943 coup against President Enrique Penaranda, had alienated the mining oligarchy with labor reforms and higher tax demands while his regime's repression of opponents eroded its popularity. The June revolt failed like the earlier attempts at the end of 1944 and mid-1945, and Villarroel remained in office.

His survival proved brief: within weeks a tripartite strike movement of teachers, students, and workers escalated into the July La Paz riots, and on 21 July 1946 a mob stormed the Palacio Quemado and lynched him, hanging his body from a lamppost in the Plaza Murillo.

Editorial Note

The dataset records this 13 June 1946 military coup attempt as failed with Villarroel remaining in office and unharmed, which matches the Lora account of a revolt on that exact date. Detailed English language coverage of the June attempt itself is thin; surrounding facts are sourced to the July collapse and regime background. Links forward to the successful July 1946 events and to the Bolivian sexenio that followed.

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.
