Cold War: The Dominican Civil War broke out due to tensions following a military coup against the democratically elected government of President Juan Bosch two years earlier.

The Cold War was a period of global geopolitical rivalry between the United States (US) and the Soviet Union (USSR) and their respective allies, the capitalist Western Bloc and communist Eastern Bloc, which began in the aftermath of the Second World War and ended with the dissolution of the Soviet Union in 1991. The term cold war is used because there was no direct fighting between the two superpowers, though each supported opposing sides in regional conflicts known as proxy wars. In addition to the struggle for ideological and economic influence and an arms race in both conventional and nuclear weapons, the Cold War was expressed through technological rivalries such as the Space Race, espionage, propaganda campaigns, embargoes, and sports diplomacy.

The Dominican Civil War, also known as the April Revolution, took place between April 24, 1965, and September 3, 1965, in Santo Domingo, Dominican Republic. It started when civilian and military supporters of the overthrown democratically elected president Juan Bosch ousted the militarily installed president Donald Reid Cabral from office. The second coup prompted General Elías Wessin y Wessin to organize elements of the military loyal to the dictator Reid ("loyalists"), initiating an armed campaign against the "constitutionalist" rebels.

Juan Emilio Bosch y Gaviño, also known as El Profesor, was a Dominican politician, historian, writer of short stories and novels, essayist, educator, and the first democratically elected president of the Dominican Republic for seven months in 1963.
