Pan-Arctic Population Movements

This chapter provides description and interpretation of the two major, well-documented episodes of Arctic-wide migrations. The Paleo-Inuit (also called Paleoeskimo or Arctic Small Tool tradition) migration began around 3,200 B.C., with penetration of the central Arctic by highly mobile, small-scale hunter-gatherer groups. By around 2,500 B.C., the entire eastern Arctic had been peopled by cultures known as Pre-Dorset, Saqqaq, and Independence I. The Thule Inuit migration began around A.D. 1200, when complex maritime-oriented groups from the western Arctic initiated an extremely rapid population movement, spanning the North American Arctic within a generation. The chapter considers the timing and nature of each migration episode, as well as the motivating factors which have been proposed for them, including climate change, social or economic hardship, and acquisition of specific resources such as bowhead whales or metal.
