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.

The Arawakan-speaking Taíno moved into Hispaniola from the north east region of what is now known as South America, displacing earlier inhabitants, c. AD 650. They engaged in farming and fishing and hunting and gathering. The fierce Caribs drove the Taíno to the northeastern Caribbean during much of the 15th century. The estimates of Hispaniola's population in 1492 vary widely, including one hundred thousand, three hundred thousand, and four hundred thousand to two million. Determining precisely how many people lived on the island in pre-Columbian times is next to impossible, as no accurate records exist. By 1492 the island was divided into five Taíno chiefdoms. The Taíno name for the entire island was either "Ayiti" or "Quisqueya".
