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.
Ecuador
In contrast, when the Incas made incursions into coastal Ecuador and the eastern Amazon jungles of Ecuador, they found both the environment and indigenous people more hostile. Moreover, when the Incas tried to subdue them, these indigenous people withdrew to the interior and resorted to guerrilla tactics. As a result, Inca expansion into the Amazon basin and the Pacific coast of Ecuador was hampered. The indigenous people of the Amazon jungle and coastal Ecuador remained relatively autonomous until the Spanish soldiers and missionaries arrived in force. The Amazonian people and the Cayapas of Coastal Ecuador were the only groups to resist Inca and Spanish domination, maintaining their language and culture well into the 21st century.
