The Great Lakes also called the Laurentian Great
Lakes and the Great Lakes of North America, are a series
of connected freshwater lakes placed mainly
in the upper mid-east region of North
America, on the Canada–United States border, which associate
to the Atlantic Ocean over the Saint Lawrence River. Containing of
Lakes Superior, Michigan, Huron (or Michigan–Huron), Erie,
and Ontario, they form the biggest group of freshwater
lakes on Earth by whole area, and second largest by total volume containing 21%
of the world's surface fresh water by volume. It would be that the encroachment of Europeans
forced many native tribes that had up until this point been rivals to form
alliances in order to stop the spread of European settlement.
