Dominican Republic, 1961 — military coup attempt

Dominican Republic (DOM)Caribbean, AmericasMay 30, 1961

Event Summary

On the night of 30 May 1961 the Dominican dictator Rafael Leonidas Trujillo, who had ruled the country with an iron grip since 1930, was ambushed and shot dead on a coastal highway outside the capital as he traveled by car to visit his mistress. The assassination was carried out by a group of conspirators including General Antonio Imbert Barrera, Antonio de la Maza, and other regime insiders who had turned against him, aided by weapons the CIA had supplied to the opposition after Trujillo's international isolation over the 1960 car bomb attack on Venezuela's President Betancourt and the murder of the Mirabal sisters. Though the killing succeeded, the planned seizure of power failed when a key conspirator faltered, and Trujillo's son Ramfis returned to launch a brutal manhunt that executed most of the plotters, only Imbert and Amiama Tio surviving.

The Trujillo family was pressured into exile by November 1961, ending the 31 year dictatorship.

On 30 May 1961 Trujillo was shot dead when his blue 1957 Chevrolet Bel Air was ambushed on a road outside the Dominican capital, but the plotters failed to take control as a key conspirator's inactivity and the absence of contingency plans doomed the coup.

Editorial Note

Date match, extensively documented. The dataset's leader fate of killed is accurate. Dataset codes it a military coup, reflecting the insider conspiracy. Connects to the Venezuela 1960-06-24 Betancourt car bomb in batch 62 and the June 1959 Dominican expedition in batch 61.

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.
