Dominican Republic in the context of "Dajabón River"

Puerto Rico (abbreviated PR), officially the Commonwealth of Puerto Rico, is a self-governing Caribbean archipelago and island organized as an unincorporated territory of the United States under the designation of commonwealth. Located about 1,000 miles (1,600 km) southeast of Miami, Florida, between the Dominican Republic in the Greater Antilles and the U.S. Virgin Islands in the Lesser Antilles, it consists of the eponymous main island and numerous smaller islands, including Vieques, Culebra, and Mona. With approximately 3.2 million residents, it is divided into 78 municipalities, of which the most populous is the capital municipality of San Juan, followed by those within the San Juan metropolitan area. Spanish and English are the official languages of the government, though Spanish predominates.

Puerto Rico was settled by a succession of Amerindian peoples beginning 2,000 to 4,000 years ago; these included the Ortoiroid, Saladoid, and Taíno. It was claimed by Spain following the arrival of Christopher Columbus in 1493 and subsequently colonized by Juan Ponce de León in 1508. Puerto Rico was contested by other European powers into the 18th century but remained a Spanish possession for the next 400 years. The decline of the Indigenous population, followed by an influx of Spanish settlers, primarily from the Canary Islands and Andalusia, and African slaves vastly changed the cultural and demographic landscape of the archipelago. Within the Spanish Empire, Puerto Rico played a secondary but strategically significant role compared to larger and wealthier colonies like Peru and New Spain. By the late 19th century, a distinct Puerto Rican identity began to emerge, centered on a fusion of European, African, and Indigenous elements. In 1898, following the Spanish–American War, Puerto Rico was acquired by the United States.

During the Age of Discovery, a large scale colonization of the Americas, involving European countries, took place primarily between the late 15th century and early 19th century. The Norse settled areas of the North Atlantic, colonizing Greenland and creating a short-term settlement near the northern tip of Newfoundland circa 1000 AD. However, due to its long duration and importance, the later colonization by Europeans, after Christopher Columbus’s voyages, is more well-known. During this time, the European colonial empires of Spain, Portugal, Great Britain, France, Russia, the Netherlands, Denmark, and Sweden began to explore and claim the Americas, its natural resources, and human capital, leading to the displacement, disestablishment, enslavement, and genocide of the Indigenous peoples in the Americas, and the establishment of several settler colonial states.

The rapid rate at which some European nations grew in wealth and power was unforeseeable in the early 15th century because it had been preoccupied with internal wars and it was slowly recovering from the loss of population caused by the Black Death. The Ottoman Empire's domination of trade routes to Asia prompted Western European monarchs to search for alternatives, resulting in the voyages of Christopher Columbus and his accidental arrival at the New World. With the signing of the Treaty of Tordesillas in 1494, Portugal and Spain agreed to divide the Earth in two, with Portugal having dominion over non-Christian lands in the world's eastern half, and Spain over those in the western half. Spanish claims essentially included all of the Americas; however, the Treaty of Tordesillas granted the eastern tip of South America to Portugal, where it established Brazil in the early 1500s, and the East Indies to Spain, where It established the Philippines. The city of Santo Domingo, in the current-day Dominican Republic, founded in 1496 by Columbus, is credited as the oldest continuously inhabited European-established settlement in the Americas.

An island is a landmass (smaller than a continent) that is surrounded by water. Many island countries are spread over an archipelago, as is the case with Indonesia, Japan, and the Philippines—these countries consist of thousands of islands. Others consist of a single island, such as Barbados, Dominica, and Nauru; a main island and some smaller islands, such as Cuba, Iceland, and Sri Lanka; a part of an island, such as Brunei, the Dominican Republic, East Timor, and the Republic of Ireland; or one main island but also sharing borders in other islands, such as the United Kingdom (Great Britain and a part of Ireland).

The list also includes two states in free association with New Zealand, the Cook Islands and Niue, as well as two states with limited diplomatic recognition which have de facto control over territories entirely on the islands, Northern Cyprus and Taiwan. In total, 50 island countries have been included in the lists.

San Juan (/ˌsæn ˈhwɑːn/ san WHAHN, Spanish: [saŋ ˈxwan]; Spanish for "Saint John") is the capital city and most populous municipality in the Commonwealth of Puerto Rico, an unincorporated territory of the United States. As of the 2020 census, it is the 57th-most populous city under the jurisdiction of the United States, with a population of 342,259. San Juan was founded by Spanish colonists in 1521, who called it Ciudad de Puerto Rico (Spanish for "Rich Port City").

Puerto Rico's capital is the second oldest European-established capital city in the Americas, after Santo Domingo, in the Dominican Republic, founded in 1496, and is the oldest European-established city under United States sovereignty. Several historical buildings are located in the historic district of Old San Juan; among the most notable are the city's former defensive walls, Fort San Felipe del Morro and Fort San Cristóbal, and La Fortaleza, the oldest executive mansion in continuous use in the Americas. These historic sites were declared a UNESCO World Heritage Site in 1983.

The Greater Antilles is a grouping of the larger islands in the Caribbean Sea, including Cuba, Hispaniola, Puerto Rico, and Jamaica, together with Navassa Island and the Cayman Islands. Seven island states share the region of the Greater Antilles, with Haiti and the Dominican Republic sharing the island of Hispaniola. Together with the Lesser Antilles, they make up the Antilles, which along with the Lucayan Archipelago, form the West Indies in the Caribbean region of the Americas.

While most of the Greater Antilles consists of independent countries, Puerto Rico and Navassa Island are unincorporated territories of the United States, while the Cayman Islands are a British Overseas Territory. The largest island is Cuba, which extends to the western end of the island group. Puerto Rico lies on the eastern end, and the island of Hispaniola, the most populated island, is located in the middle. Jamaica lies to the south of Cuba, while the Cayman Islands are located to the west. The state of Florida is the closest point in the U.S. mainland to the Greater Antilles, while the Florida Keys, though not part of the Greater Antilles, is an island group north of Cuba.

The Taíno were the Indigenous peoples of the Greater Antilles and surrounding islands. At the time of European contact in the late 15th century, they were the principal inhabitants of most of what is now The Bahamas, Cuba, the Dominican Republic, Haiti, Jamaica, Puerto Rico, and the northern Lesser Antilles. The Lucayan branch of the Taíno were the first New World people encountered by Christopher Columbus, in the Bahama Archipelago on October 12, 1492. The Taíno historically spoke an Arawakan language. Granberry and Vescelius (2004) recognized two varieties of the Taino language: "Classical Taino", spoken in Puerto Rico and most of Hispaniola, and "Ciboney Taino", spoken in the Bahamas, most of Cuba, western Hispaniola, and Jamaica. They lived in agricultural societies ruled by caciques with fixed settlements and a matrilineal system of kinship and inheritance. Taíno religion centered on the worship of zemis. The Taíno are sometimes also referred to as Island Arawaks or Antillean Arawaks. Indigenous people in the Greater Antilles did not refer to themselves originally as Taíno; the term was first explicitly used in this sense by Constantine Samuel Rafinesque in 1836.

Historically, anthropologists and historians believed that the Taíno were no longer extant centuries ago, or that they gradually merged into a common identity with African and Hispanic cultures. Scholarly attitudes to Taíno survival and resurgence began to change around the year 2000. Many people today identify as Taíno and many more have Taíno descent, most notably in Puerto Rico, Cuba, and Dominica. A substantial number of Puerto Ricans, Cubans, and Dominicans have Indigenous mitochondrial DNA, which may suggest Taíno descent through the direct female line, especially in Puerto Rico. While some communities describe an unbroken cultural heritage passed down through the generations, often in secret, others are revivalist communities who seek to incorporate Taíno culture into their lives.

The Central American Integration System (Spanish: Sistema de la Integración Centroamericana, or SICA) has been the economic and political organization of Central American states since 1 February 1993. On 13 December 1991, the ODECA countries (Spanish: Organización de Estados Centroamericanos) signed the Protocol of Tegucigalpa, extending earlier cooperation for regional peace, political freedom, democracy and economic development. SICA's General Secretariat is in El Salvador.

In 1991, SICA's institutional framework included Guatemala, El Salvador, Honduras, Nicaragua, Costa Rica and Panama. Belize joined in 1998 as a full member, while the Dominican Republic became an associated state in 2004 and a full member in 2013. Mexico, Chile and Brazil became part of the organization as regional observers, and the Republic of China, Spain, Germany, Georgia and Japan became extra-regional observers. SICA has a standing invitation to participate as observers in sessions of the United Nations General Assembly, and maintains offices at UN Headquarters.

Haiti, officially the Republic of Haiti, is a country in the Caribbean on the island of Hispaniola in the Caribbean Sea, east of Cuba and Jamaica, and south of the Bahamas. It occupies the western three-eighths of the island, which it shares with the Dominican Republic. Haiti is the third largest country in the Caribbean, and with an estimated population of 11.4 million, is the most populous Caribbean country. The capital and largest city is Port-au-Prince.

Haiti was originally inhabited by the Taíno people. In 1492, Christopher Columbus established the first European settlement in the Americas, La Navidad, on its northeastern coast. The island was part of the Spanish Empire until 1697, when the western portion was ceded to France and became Saint-Domingue, dominated by sugarcane plantations worked by enslaved Africans. The 1791–1804 Haitian Revolution made Haiti the first sovereign state in the Caribbean, the second republic in the Americas, the first country in the Americas to officially abolish slavery, and the only country in history established by a slave revolt. The 19th century saw political instability, international isolation, debt to France, and failed invasions of the Dominican Republic, including a costly war. U.S. forces occupied Haiti from 1915 to 1934, followed by dictatorial rule of the Duvalier family (1957–1986). Following a coup d'état in 1991, a U.S.-led multinational force intervened in 1994; a second coup in 2004 was followed by a United Nations intervention. In the 2010s, a catastrophic earthquake and a large-scale cholera outbreak devastated the country.
