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.

The Federal Union: A History of the United States to 1877 (originally published as "The Federal Union: A History of the United States to 1865)" is history of the United States written by John D.

Four revised editions followed that also covered the Reconstruction Era up to 1877, and accordingly were published with an updated subtitle. The fifth and final edition appeared in 1970.
