Inuit (‘the people’) are a group of culturally similar indigenous peoples inhabiting the Arctic and subarctic regions of Greenland, Labrador, Quebec, Nunavut, the Northwest Territories, particularly around the Arctic Ocean, and Alaska.

Greenlandic Inuit are descendants of Thule migrations from Canada by 1100 CE. In 1985, Inuit of Greenland were classified as Danish citizens and, as such, remain citizens of the European Union. In the United States, the Alaskan Iñupiat are traditionally located in the Northwest Arctic Borough, on the Alaska North Slope, and on Little Diomede Island.

Many individuals who would have historically been referred to as “Eskimo” find that term offensive or forced upon them in a colonial way; “Inuit” is now a common autonym for a large sub-group of these people. The word “Inuit” (varying forms Iñupiat, Inuvialuit, Inughuit, etc.), however, is an ancient self-referential to a group of peoples which includes at most the Iñupiat of northern Alaska. Therefore, the Aleut (Unangan) and Yupik peoples (Alutiiq/Sugpiaq, Central Yup’ik, Siberian Yupik), who live in Alaska and Siberia, at least at an individual and local level, generally do not self-identify as “Inuit”.
