Skræling (Old Norse and Icelandic: skrælingi, plural skrælingjar) is the name the Norse Greenlanders used for the peoples they encountered in North America and Greenland.[1] In surviving sources, it is first applied to the Thule people, the proto-Inuit group with whom the Norse coexisted in Greenland after about the 13th century. In the sagas, it is also used for the peoples of the region known as Vinland whom the Norse encountered during their expeditions there in the early 11th century.
