Hispaniola
The primary indigenous group on the island of Hispaniola was the Arawak/Taíno people. The Arawak tribe originated in the Orinoco Delta, spreading from Venezuela. They travelled to Hispaniola around 1200 CE. Each society on the island was a small independent kingdom with a lead known as a cacique. In 1492, which is considered the peak of the Taíno, there were five different kingdoms on the island, the Xaragua, Higuey (Caizcimu), Magua (Huhabo), Ciguayos (Cayabo or Maguana), and Marien (Bainoa). Many distinct Taíno languages also existed in this time period. There is still heated debate over the population of Taíno people on the island of Hispaniola in 1492, but estimates range upwards of 750,000.
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.
