Bolivia, 1960 — dissident coup attempt

Bolivia (BOL)South America, AmericasMarch 19, 1960

Event Summary

The dataset records an attempted dissident coup in Bolivia on 19 March 1960, during the final months of Hernan Siles Zuazo's MNR government, as the country moved toward the June 1960 elections that would return Victor Paz Estenssoro to the presidency. The period was marked by the continuing economic strain of the IMF stabilization program, the deepening split within the MNR between the factions of Siles, Paz Estenssoro, and the labor leader Juan Lechin, and recurrent plotting by the conservative Bolivian Socialist Falange, which had already staged failed risings in 1958 and 1959. Any coup attempt in March 1960 came within that pre-electoral turbulence and did not unseat Siles Zuazo, who completed his term and handed power to Paz Estenssoro in August 1960.

The MNR would hold power until the military coup of November 1964.

Editorial Note

No discrete documentation of a coup attempt precisely on 19 March 1960 was found in accessible English sources this session; the entry records the dataset's coding and the verified context of the end of the Siles Zuazo term and the recurrent FSB plotting, with plotter identity for this specific date unconfirmed, flagged. Follows the three 1958 to 1959 Bolivia records in batch 61.
