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.
Provincias Internas
According to Humboldt, Spanish and Criollo people comprised the majority of the inhabitants in the Provincias Internas by 1810. This was caused by the arrival of more waves of new Spanish settlers, racial segregation among castes and especially by a catastrophic decrease in numbers of the indigenous peoples.
