By the time the known history of the Lakes really begins their inhabitants had degenerated into warlike, ferocious savages, bent upon battle and extermination, and for the most part constantly embroiled in war of one kind or another. From Lake Ontario to the end of Superior the Lake regions were one great battle-ground, and this sanguinary history had extended so far into the past that with the coming of the first French explorers the Indians could give no comprehensive idea of when it had begun. At this time, early in the seventeenth century, the Lake country was the bone of contention among three quarters of the aborigines of North America. There was hardly a tribe that was not fighting some one of its neighbours, and the remnants of vanquished nations were constantly fleeing from their enemies and escaping total extermination by seeking safety in the West and South. In Northern Michigan and in Wisconsin there lived three branches of the Algonquin tribe, the Ottawas, the Ojibwas, and the Pottawatomies. The Ottawas had been driven westward, and the Ojibwas at this time were invading the hunting grounds of the Crees, who were entrenched on the northern shore of Lake Superior, their territory extending northward to Hudson Bay. On their west, the Ojibwas were also at war with the powerful Dakotas, who, fighting eastward from the Mississippi, had secured a foothold on Superior. To the eastward, encroaching upon the tribes of Lake Ontario, were the Iroquois, or Five Nations, consisting of the Mohawks, Oneidas, Onondagas, Cayugas, and the Senecas. Between these and the fierce Algonquins of the Upper Lakes were wedged the Hurons and the Eries, fighting vainly against the almost total extermination which became their fate a little later. It was in the war between 1650 and 1655 that both the Eries and the Neuters, on the southern shore of Lake Erie, were wiped out of existence by the Iroquois, and it was about this same time that the Hurons received their death-blow. The few that escaped fled to the Mississippi and promptly became involved in a war with the Sioux. Reduced to a pitiable remnant the once powerful Sacs and Foxes were awaiting their end along Green Bay.
