Venezuela, 1958 — military coup attempt

Venezuela (VEN)South America, AmericasSeptember 7, 1958

Event Summary

The dataset records an attempted military coup in Venezuela on 7 September 1958, the second of the risings that the transitional government under Rear Admiral Wolfgang Larrazabal weathered during the year between the fall of Perez Jimenez and the inauguration of an elected president. This attempt, associated with Defense Minister Colonel Jesus Maria Castro Leon and hardline officers uneasy at the democratic opening and the legalization of leftist parties, sought to reverse the direction of the provisional junta. It was thwarted because enough officers remained loyal to the transition, and Castro Leon was forced out.

The failed rising did not derail the handover: the December 1958 election proceeded, bringing Democratic Action's Romulo Betancourt to the presidency in February 1959, and Castro Leon would try again with a border incursion in 1960 that also failed.
