GUANCHES, GUANCHIS or Guanchos (native Guanchinet; Guan = person, Chinet = Teneriffe, - " ` man of Teneriffe," corrupted, according to Nunez de la Pena, by Spaniards into Guanchos), the aboriginal inhabitants of the Canary Islands.
This would suggest that the Guanches were not the first inhabitants, and from the absence of any trace of Mahommedanism among the peoples found in the archipelago by the Spaniards it would seem that this extreme westerly migration of Berbers took place between the time of which Pliny wrote and the conquest of northern Africa by the Arabs.
Many of the Guanches fell in resisting the Spaniards, many were sold as slaves, and many conformed to the Roman Catholic faith and married Spaniards.
No inscriptions have been found in these two islands, and therefore it would seem that the true Guanches did not know how to write.
The political and social institutions of the Guanches varied.
