The vikings attempting to settle in north america were defeated by which group?

Thule

Explanation:

The Vikings, or Norse, were the first Europeans that managed to reach North America, long before Columbus did, though unlike him, they were keeping it as a secret. They built three permanent settlements on Greenland, and several short term along the eastern coast of North America though never really settled on the continent itself. The Vikings managed to survive for around four centuries on Greenland, and they managed to prosper during this time because they had lot of things to trade with mainland Europe. Unfortunately for them, they were not in good relations with the Thule people, which are the ancestors of the Inuit/Eskimo people. It is suggested that a conflict occurred between the two groups and that the winners were the Thule people, putting end to the Viking settlements in North America.
