The Second Triumvirate was a short-lived military junta that controlled the Dominican Republic after the Triumvirate of 1963 created after the coup that overthrew Juan Bosch fell apart.
[1] Brutal repression tactics by the military to eliminate rebels & suppress protests led the members of the 1963 civilian junta to step down; Emilio de los Santos Manuel on December 22, 1963, Ramón Tapia Espinal on April 8, 1964 & finally Enrique Tavares Espaillat on June 27, 1964.

Donald Joseph Reid Cabral became the temporary minister of the armed forces & national police making him the de facto leader of the country.
Austerity reforms & the firing of military personnel not loyal to Reid would lead to a military rebellion on April 24, 1965, that demanded Bosch's restoration.
