Thule people

The Thule (/ˈtuːli/ or /ˈθjuːl/) or proto-Inuit were the ancestors of all modern Inuit. They developed in coastal Alaska by AD 1000 and expanded eastwards across Canada, reaching Greenland by the 13th century. In the process, they replaced people of the earlier Dorset culture that had previously inhabited the region. The appellation "Thule" originates from the location of Thule (relocated and renamed Qaanaaq in 1953) in northwest Greenland, facing Canada, where the archaeological remains of the people were first found at Comer's Midden. The links between the Thule and the Inuit are biological, cultural, and linguistic.

Evidence supports the idea that the Thule (and also the Dorset, but to a lesser degree) were in contact with the Vikings, who had reached the shores of Canada in the 11th century. In Viking sources, these peoples are called the Skræling. Some Thule migrated southward, in the "Second Expansion" or "Second Phase". By the 13th or 14th century, the Thule had occupied an area currently inhabited by the Central Inuit, and by the 15th century, the Thule replaced the Dorset culture. Intensified contacts with Europeans began in the 18th century. Compounded by the already disruptive effects of the "Little Ice Age" (1650–1850), the Thule communities broke apart, and the people were henceforward known as the Eskimo, and later, Inuit.
