How did Inuit peoples migrate to Greenland from North America?

Inuit peoples migrated to Greenland from North America by utilizing the islands of the Canadian Arctic as stepping stones. This movement was part of a series of migrations spanning thousands of years, with the most recent arrival being the Thule culture, which reached northern Greenland around 1100 CE.1

Following their arrival, the Thule people expanded and developed into the Inugsuk culture during the 12th and 13th centuries. This culture was characterized by advanced hunting techniques, utilizing kayaks, umiaks (large skin boats), and dog-drawn sleds for transportation. The Inugsuk culture eventually spread southward along the west coast of Greenland and later moved northward along the east coast, where they interacted with earlier cultural elements. By the 13th century, these expanding Inuit groups also began to interact with the Norse settlers who had established colonies on the island in the late 10th century.234
