The Vikings traded, hunted with the Arctic inhabitants and fought with the Indians
After establishing settlements in Iceland and Greenland in the ninth and tenth centuries A.D., the Vikings reached what is now Newfoundland, Canada, around A.D. 1000. In the 13th century, the Inuit and Thule Norse hunted walruses in the high Arctic, according to a new study. Medieval walrus ivory may indicate trade between the Norse and Native Americans hundreds of years before Columbus, the study found.
