On September 25, 1963, after seven months in office, Juan Bosch, the Dominican Republic's first democratically elected president since the Trujillo era, was overthrown in a bloodless coup by a group of senior military commanders led by General Elias Wessin y Wessin, who accused Bosch and his cabinet of being corrupt and pro-communist. Bosch's liberal April 1963 constitution had alienated landholders, the Catholic Church, industrialists, and the military, and his refusal to outlaw the Communist Party, answered by his demand for Wessin's resignation, precipitated the strike. Bosch was arrested and deported by ship toward Guadeloupe on September 28, flying on October 1 to Puerto Rico, where he spent his exile.
The military installed a three-man junta, declared a state of siege, dissolved the legislature, and pronounced the 1963 constitution nonexistent; under international and domestic pressure it gave way to the civilian Triumvirate of de Los Santos, Tavares Espaillat, and Tapia Espinal, with businessman Donald Reid Cabral soon emerging as the dominant figure. Constitutionalist officers demanding Bosch's restoration rose on April 24, 1965, triggering the civil war and the United States intervention.

On September 25, after only seven months in power, Bosch was overthrown and placed under arrest in a bloodless coup led by Elias Wessin y Wessin, General Antonio Imbert Barrera, and other military leaders who accused Bosch and his cabinet of being corrupt and pro-communist; the junta declared a nationwide state of siege, imposed a curfew, dissolved the legislature, deemed the new constitution nonexistent, and six right leaning parties assisted in forming the civilian junta of Emilio de Los Santos, Manuel Enrique Tavares Espaillat, and Ramon Tapia Espinal.
Bosch, the first democratically elected president after Trujillo's assassination, was deported to Guadeloupe on 28 September 1963 and flew to Puerto Rico on 1 October 1963, where he spent the remainder of his exile; less than two years later the constitutionalist rebellion of April 24, 1965 demanding his restoration removed the junta, and the United States dispatched 42,000 troops in Operation Power Pack during the ensuing civil war.

Bosch's liberal and democratic constitution of April 29 alienated four powerful groups: landholders frightened by the prohibition against latifundia, the Catholic Church angered by its secular character, industrialists who saw it as worker oriented, and a military that considered its powers curtailed; the military deposed him on September 25, 1963.

Contemporary reporting recorded that when Bosch refused Wessin y Wessin's demand to outlaw the Communist Party and instead demanded the general's resignation, Wessin staged the bloodless September 1963 coup that ousted Bosch and sent him into exile in Puerto Rico, with Donald Reid Cabral emerging as leader of the civilian triumvirate that succeeded Bosch.

Editorial Note
Fate nuance: Bosch was first arrested, then deported, so the dataset's fled the country reflects a forced departure rather than a voluntary escape; the record documents the arrest, the September 28 deportation, and the October 1 arrival in Puerto Rico. One later account states the coup makers installed Donald Reid Cabral as president, but the contemporaneous sequence was a military junta, then the civilian Triumvirate, with Reid Cabral becoming its dominant member; the record follows the detailed accounts. Arc link: the April 1965 constitutionalist countercoup and United States intervention flow directly from this event.
