History of Haiti
Following the arrival of Europeans, La Hispaniola's indigenous population suffered greatly to near extinction, in possibly the worst case of depopulation in the Americas. A commonly accepted hypothesis attributes the high mortality of this colony in part to European diseases to which the natives had no immunity. A small number of Taínos were able to survive and set up villages elsewhere. Spanish interest in Hispaniola began to wane in the 1520s, as more lucrative gold and silver deposits were found in Mexico and South America. Thereafter, the population of Spanish Hispaniola grew at a slow pace.
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.
