Leif Erikson
Leif Erikson or Leif Ericson ( 970 – c. 1020) was a Norse explorer from Iceland. He was the first known European to have set foot on continental North America (excluding Greenland), before Christopher Columbus. According to the Sagas of Icelanders, he established a Norse settlement at Vinland, tentatively identified with the Norse L'Anse aux Meadows on the northern tip of Newfoundland in modern-day Canada. Later archaeological evidence suggests that Vinland may have been the areas around the Gulf of St. Lawrence and that the L'Anse aux Meadows site was a ship repair station.
Historical revisionism
In recounting the European colonization of the Americas, some history books of the past paid little attention to the indigenous peoples of the Americas, usually mentioning them only in passing and making no attempt to understand the events from their point of view. This was reflected in the description of Christopher Columbus having discovered America. The portrayal of these events has since been revised, avoiding the word "discovery."
