United States occupation of the Dominican Republic: American troops land in the Dominican Republic to "forestall establishment of a Communist dictatorship" and to evacuate US Army troops.

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.

The Dominican Republic is a country in the Caribbean located on the island of Hispaniola in the Greater Antilles of the Caribbean Sea in the North Atlantic Ocean. It shares a maritime border with Puerto Rico to the east and a land border with Haiti to the west, occupying the eastern five-eighths of Hispaniola which, along with Saint Martin, is one of only two islands in the Caribbean shared by two sovereign states. In the Antilles, the country is the second-largest nation by area after Cuba at 48,671 square kilometers (18,792 sq mi) and second-largest by population after Haiti with approximately 11.4 million people in 2024, of whom 3.6 million reside in the metropolitan area of Santo Domingo, the capital city.

Communism is a sociopolitical, philosophical, and economic ideology within the socialist movement, whose goal is the creation of a communist society, a socioeconomic order centered on common ownership of the means of production, distribution, and exchange that allocates products in society based on need. A communist society entails the absence of private property and social classes, and ultimately money and the state.
