Ambrotype of an Ojibwa Man wearing western dress and snow goggles, c. 1850 The Ojibwe (also Ojibwa or Ojibway) or Chippewa (also Chippeway) are the largest groups of Native Americans–First Nations north of Mexico. They are divided between Canada and the United States. In Canada, they are the second-largest population among First Nations, surpassed only by Cree. In the United States, they had the fourth-largest population among Native American tribes, surpassed only by Navajo, Cherokee and the Lakota. Because many Ojibwe were historically formerly located mainly around the outlet of Lake Superior, which the French colonists called Sault Ste. Marie, they referred to the Ojibwe as Saulteurs. Ojibwe who subsequently moved to the prairie provinces of Canada have retained the name Saulteaux. Ojibwe who were originally located about the Mississagi River and made their way to southern Ontario are known as the Mississaugas.
