The five island nations that make up the Greater Antilles are Cuba, the Dominican Republic, Haiti, Jamaica and Puerto Rico. The Dominican Republic and Haiti are separate nations, but both are located on one island, Hispaniola.
Though they are not an independent nation, the Cayman Islands can also be included in the Greater Antilles.
The term "Antilles" comes from medieval European cartography, where it was used to indicate a land that was considered to be mysterious. Geologists believe the islands are geographically linked as the summits of a mountain chain that have been raised and submerged throughout the planet's history.
