Indigenous peoples of the Caribbean
The Classic Taíno lived in eastern Cuba, Hispaniola, and Puerto Rico. They spoke a dialect called Classic Taíno. Compared to their neighbors, the Classic Taíno had substantially developed agricultural societies. Puerto Rico was divided into twenty chiefdoms which were organized into one united kingdom or confederation, Borinquen. Hispaniola was divided into roughly 45 chiefdoms, which were organized into five kingdoms under the leadership of the chief of each area's premier chiefdom. Beginning around 1450, Classic Taíno from Hispaniola began migrating to eastern Cuba; they are conventionally known as the Cuban Taíno. The Cuban Taíno gained power over some of Cuba's earlier Western Taíno inhabitants, the Ciboney, but no regional or island-wide political structure had developed on the island at the time of Spanish colonization of the Americas.
Nicaraguans
It is known that Nicaragua was inhabited by Paleo-Indians as far back as 6000 years. This is confirmed by archaeological evidences, mainly ceramics and statues made of volcanic stone like the ones found on the island of Zapatera and petroglyphs found on Ometepe island. At the end of the 15th century, western Nicaragua was inhabited by several different indigenous peoples related by culture to the Mesoamerican civilizations of the Aztec and Maya, and by language to the Mesoamerican Linguistic Area. However, within three decades an estimated Indian population of one million plummeted to a few tens of thousands, as approximately half of the indigenous people in western Nicaragua died of diseases brought by the Spaniards. The central region and the Caribbean coast of Nicaragua were inhabited by indigenous peoples who were mostly Chibcha-related groups that had migrated from South America, primarily what is now Colombia and Venezuela. These groups include the present-day Miskitos, Ramas and Sumos who lived a less sedentary life based on hunting and gathering, as well as fishing and performing slash-and-burn agriculture.
