Nunavut has been the homeland for Inuit for over  4,000 years. Archaeologists and geneticists are now certain that the predecessors of today’s Inuit originated in the area of the Bering Strait, which separates Asia from North America. The first indigenous group, known as Paleo-Eskimos, crossed the Bering Strait sometime around 3000 BC and moved into the Canadian Arctic Archipelago around 2500 BC, apparently because of a change in climate. From there they followed marine mammals and herds of big game land animals across all of Nunavut to Greenland. The timeline of inhabitation in this area is as follows:

• Paleo-Eskimo Culture: 2500 BC to 1500 BC
• Pre-Dorset Culture (‘Saqqaq’): 2500 BC to 500 BC
• Dorset Culture (‘Tuniit’ or ‘Sivullirmiut’): 500 BC to 1500 AD
• Thule Culture (Proto-Inuit): 1000 AD to 1600 AD
• Inuit Culture: 1600 AD to present-day

Paleo-Eskimo people inhabited the entire Arctic from Chukotka in present-day Russia across North America to Greenland prior to the rise of the ancient Thule and modern Inuit. The first known Paleo-Eskimo culture in Nunavut developed around 2500 BC.

He was found in Greenland and he belonged to the Saqqaq culture. Based on his genome, scientists conclude that his people migrated from Siberia to North America 5,000 years ago, then to Greenland 500 years later. This ancient man — dubbed ‘Inuk’ — had A+ blood type and genes suggesting he was adapted to cold weather, with brown eyes, brownish skin and dark hair, with a likelihood of male pattern baldness in his old age.

Ancient Nunavut descendants of Paleo-Eskimo people include the Pre-Dorset and Dorset cultures. The Dorset people were the last major Paleo-Eskimo culture living in the Arctic before the migration east from present-day Alaska of the Thule, the direct ancestors of the Inuit.

Dorset culture used unique technology related to hunting and tool making.

The Dorset culture (also called the Dorset Tradition) was a Paleo-Eskimo descendent group of people living in Nunavut from 500 BC to 1500 AD who preceded the arrival of the Thule people. Through contact with the more advanced Thule culture, and potentially also through intermarriage, some anthropologists believe that modern Inuit are at least related culturally and perhaps also biologically to the ancient Dorset.

They made distinctive triangular blades, soapstone lamps and engraving tools called burins. Scholars believe that the Dorset (and later the Thule) had contact with Norse sailors who visited Baffin Island from 1000 AD to 1450 AD. The Vikings derisively called these people ‘Skræling’ yet they outlasted the ancient Norse!

The Dorset were, however, nearly extinct by 1500 AD. They had difficulty adapting to the Medieval Warm Period (950 AD – 1250 AD) and were largely displaced by the superior Thule culture. Certain Inuit legends describe their ancestors driving away the people they called ‘Tuniit’ or ‘Sivullirmiut’ (first inhabitants). According to Inuit legend, they were timid giants, people who were taller and stronger than the Thule, but who were easily scared off.

The last vestige of Dorset people disappeared in the early 20th century. A small, isolated community of Dorset known as the Sallirmiut survived until the winter of 1902-1903 on Coats, Walrus and Southampton Islands in Hudson Bay near the present-day Nunavut community of Coral Harbour. DNA testing has confirmed these people were directly related to the Dorset.

The name ‘Thule’ originates from the community of Thule (renamed Qaanaaq in 1953) in northwestern Greenland where the archaeological remains of these unique people were first discovered.

Thule winter settlements usually had one to four houses sheltering up to ten people each.

The Thule people, sometimes called proto-Inuit, were the direct ancestors of all modern Inuit. They were established in coastal Alaska by 1000 AD 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 links between the Thule and the Inuit are biological, cultural, and linguistic.

Archaeological evidence has demonstrated that the Thule (and also the Dorset, but to a lesser degree) were in contact with the Norse, who had reached the shores of Canada by 1000 AD. In the Viking Sagas, this indigenous Nunavut people was also called ‘Skræling.’

Some Thule people migrated southward in the ‘Second Expansion’ or ‘Second Phase’ of their history. From 1200 AD to 1300 AD, the Thule occupied the entire area currently inhabited by the Central Inuit. By 1400 AD, the Thule had effectively replaced most of the Dorset culture. Contact with Europeans intensified in the 18th century, disrupting Thule traditions. Compounded by the climatic effects of the Little Ice Age (1650 AD – 1850 AD), many Thule communities broke apart and this nomadic indigenous people became known to Europeans and Americans as Eskimo and later, more correctly, as Inuit.

The Thule people are recognized historically for using slate knives, umiaks, sealskin floats and toggling harpoons. Their technology was superior to the Dorset culture. Thule people subsisted primarily on marine wildlife species — especially large sea mammals.

Some Thule settlements had more than a dozen houses, but were rarely used by more than fifty people at any one time. Their houses were constructed of whalebones covered with hides and sod. Archaeological remains of these ancient Thule structures, including food cache sites, kayak stands, hunting blinds, fox traps and other artifacts are found all across Nunavut.
