图勒人是所有现代因纽特人的祖先。他们在公元1000年左右发展于阿拉斯加地区，后扩展到加拿大地区，于13世纪到达格陵兰。在这期间，他们取代了多尔塞特文化。有确信的证据表明他们与维京人有联系。

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.
