Taíno
The Taíno were an indigenous people of the Caribbean. At the time of European contact in the late fifteenth century, they were the principal inhabitants of most of Cuba, Hispaniola (the Dominican Republic and Haiti), Jamaica, Puerto Rico, The Bahamas and the northern Lesser Antilles. The Taíno were the first New World peoples to be encountered by Christopher Columbus during his 1492 voyage. They spoke the Taíno language, an Arawakan language.
Guanches
Strictly speaking, the Guanches were the indigenous peoples of Tenerife. The population seems to have lived in relative isolation up to the time of the Castilian conquest, around the 14th century (though Genoese, Portuguese, and Castilians may have visited there from the second half of the 8th century onwards). The name came to be applied to the indigenous populations of all the seven Canary Islands, those of Tenerife being the most important or powerful.
