Mainland Nunavut was first populated approximately 4500 years ago by the
Pre-Dorset, a diverse
Paleo-Eskimo culture that migrated westward from the
Bering Strait region, when the region was a geographical connection between Asia and America, called
Beringia. Evidence suggests the Pre-Dorset culture was seasonally mobile, moving between settlements to take advantage of resources.
Dorset culture The Pre-Dorset culture was succeeded by the
Dorset culture about 2800 years ago. Differences between the Pre-Dorset and Dorset cultures include those in
lithic technology, art, and styles of building. The Dorset culture additionally lacked the bow and arrow, which had been utilized by the pre-Dorset. The Dorset culture has been assumed to have developed from the Pre-Dorset, however the relationship between the two remains unclear.
Thule 's voyages to the region The
Thule people, ancestors of the modern
Inuit, began migrating into the
Northwest Territories and Nunavut from Alaska in the 11th century. By 1300, the geographic extent of Thule settlement included most of modern Nunavut. A number of hypotheses have been developed to explain the Thule migration. The historically dominant model posited by
Robert McGhee holds that changes in
bowhead whale populations brought about by the
Medieval Warm Period drew Thule hunters westward. Other hypotheses connect the migration to
population pressure, warfare, over-hunting, and Greenlandic iron deposits. The migration of the Thule people coincides with the decline of the Dorset, who died out between 800 and 1500. While Thule settlers may have adopted Dorset harpoon and hunting technology, there is virtually no evidence confirming contact between the two populations.
European exploration The written historical accounts of Nunavut begin in 1576, with an account by English explorer,
Martin Frobisher. Frobisher, while leading an expedition to find the
Northwest Passage, thought he had discovered gold ore around the body of water now known as
Frobisher Bay on the coast of
Baffin Island. While the ore turned out worthless, Frobisher made the first recorded European contact with the
Inuit. Other explorers in search of the elusive Northwest Passage followed in the 17th century, including
Henry Hudson,
William Baffin and
Robert Bylot. Despite these explorations, these events ultimately had no significant impact on Nunavut and its peoples. Rudimentary governance and social services were administered via trading posts owned by the HBC or religious organizations led by Christian missionaries. The fur trade ultimately led to many Inuit voluntarily or forcefully relocating to other locales along with abandoning traditional hunting and subsistence in favor of
fur trapping. Despite the
Northwest Territories government theoretically exercising control of the region, Nunavut was generally left alone until the aftermath of
World War II. ==20th century==
