Dominican Republic–Haiti border in the context of "Dominican Republic"

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.

The native Taíno people had inhabited Hispaniola prior to European contact, dividing it into five chiefdoms. Christopher Columbus claimed the island for Castile, landing there on his first voyage in 1492. The colony of Santo Domingo became the site of the first permanent European settlement in the Americas. In 1697, Spain recognized French dominion over the western third of the island, which became the independent First Empire of Haiti in 1804. A group of Dominicans deposed the Spanish governor and declared independence from Spain in November 1821, but were annexed by Haiti in February 1822. Independence came 22 years later in 1844, after victory in the Dominican War of Independence. The next 72 years saw several civil wars, failed invasions by Haiti, and a brief return to Spanish colonial status, before permanently ousting the Spanish during the Dominican Restoration War of 1863–1865. From 1930, the dictatorship of Rafael Trujillo ruled until his assassination in 1961. Juan Bosch was elected president in 1962 but was deposed in a military coup in 1963. The Dominican Civil War of 1965 preceded the authoritarian rule of Joaquín Balaguer (1966–1978 and 1986–1996). Since 1978, the Dominican Republic has moved towards representative democracy.
