The area was inhabited for thousands of years by Amerindians. At the time of European encounter, the Napeano and Iquito peoples occupied the area. They had small seasonal settlements and were nomadic hunter-gatherers, living in close association with the rivers. The city name of Iquitos is derived from a group of native people called Iquitos by the Spaniards. They had previously inhabited areas along the rivers Pastaza, Arabela, Tigre, Nanay, and Curaray. Eventually, the native Iquito migrated to the area around the rivers Nanay, Amazonas, Itaya, and the Lake Moronacocha.
