The Arawakan-speaking Taíno moved into Hispaniola from the north east region of what is now known as South America, displacing earlier inhabitants, c. 650 C.E. 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 tens of thousands, 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".
