Inuit such as the Nunatamiut (Uummarmiut), who inhabited the Mackenzie River delta area, often engaged in warfare.The more sparsely settled Inuit in the Central Arctic, however, did so less often.The most southern "officially recognized" Inuit community in the world is Rigolet in Nunatsiavut.South of Nunatsiavut, the descendants of the southern Labrador Inuit in Nunatu Kavut continued their traditional transhumant semi-nomadic way of life until the mid-1900s.The Greenlandic Inuit are descendants of indigenous migrations from Canada.They are citizens of Denmark, although not of the European Union. They had split from the related Aleut group about 4,000 years ago and from northeastern Siberian migrants, possibly related to the Chukchi language group, still earlier. They were thought to have become completely extinct as a people by about 1400 or 1500. Collins determined that, based on the ruins found at Native Point, the Sadlermiut were likely the last remnants of the Dorset culture, or Tuniit.
Martin Frobisher's 1576 search for the Northwest Passage was the first well-documented post-Columbian contact between Europeans and Inuit.In contrast to other Tuniit populations, the Aleut and Sadlermiut benefited from both geographical isolation and their ability to adopt certain Thule technologies.In Canada and Greenland, Inuit circulated almost exclusively north of the "Arctic tree line", the effective southern border of Inuit society.However, aboriginal peoples in Canada and Greenlandic Inuit view "Eskimo" as pejorative, and "Inuit" is more commonly used in self-reference for these groups.The Inuit live throughout most of Northern Canada in the territory of Nunavut, Nunavik in the northern third of Quebec, Nunatsiavut and Nunatu Kavut in Labrador, and in various parts of the Northwest Territories, particularly around the Arctic Ocean.
