The Dorset culture (also called the Dorset Tradition) was a Paleo-Eskimo culture (500 BC to between 1000 and 1500 AD) that preceded the Inuit in the Arctic of North America. It is named after Cape Dorset in Nunavut, Canada where the first evidence of its existence was found. The culture has been defined as having four phases due to the distinct differences in the technologies relating to hunting and tool making. Artifacts include distinctive triangular end-blades, soapstone lamps, and burins.
The Dorset were first identified as a separate culture in 1925. The Dorset appear to have been extinct by 1500 at the latest and perhaps as early as 1000. The Thule people, who began migrating east from Alaska in the 11th century, ended up spreading through the lands previously inhabited by the Dorset. There is no strong evidence that the Inuit and Dorset ever met. Modern genetic studies show the Dorset population were distinct from later groups and that "[t]here was virtually no evidence of genetic or cultural interaction between the Dorset and the Thule peoples."
Inuit legends recount them encountering people they called the Tuniit (singular Tuniq) or Sivullirmiut "First Inhabitants". According to legend, the First Inhabitants were giants, taller and stronger than the Inuit but afraid to interact and "easily put to flight." Scholars now believe the Dorset and the later Thule people were the peoples encountered by Norsemen who visited the area. The Norse called these indigenous peoples skræling.
In 1925 anthropologist Diamond Jenness received some odd artifacts from Cape Dorset. As they were quite different from those of the Inuit, he speculated that they were indicative of an ancient, preceding culture. Jenness named the culture "Dorset" after the location of the find. These artifacts showed a consistent and distinct cultural pattern that included sophisticated art distinct from that of the Inuit. For example, the carvings featured uniquely large hairstyles for women, and figures of both sexes wearing hoodless parkas with large, tall collars. Much research since then has revealed many details of the Dorset people and their culture.
