Beginning in the 1670s, the French began to explore and colonize the country of Ohio and Illinois from the Mississippi and Ohio rivers, and they founded the Tassinong Post to trade with western tribes. The Iroquais destroyed them to keep control of the fur trade with the Europeans. The Iroquois drove the Mannahoac tribe out of the northern region of Piedmont in 1670 and claimed the country as a hunting ground by the right of conquest. The English recognized this claim in 1674 and 1684, but acquired the land of the Iroquois by treaty of 1722. After the effective destruction of the Wendat nation and neutrality, the Haudenosaunee extended its attacks against the Mohicans, Sokoki and Abenaki. While in Quebec, they rushed to Tadoussac and north across Mistassini Lake. Despite fierce opposition from Susquehannock and Erie, the Haudenosaunee Confederacy made peace with the French in 1653. After concentrated hedenosaunee attacks the Erie 1657 was absorbed. New hostilities in 1659/60 on a broad front weighed heavily on the Confederacy, and the Haudenosaunee again sought peace with the French. But a contract that embraces all groups was not concluded until 1667, after the Carignan-Saliéres regiment set fire to Mohawk villages and food supplies.
By 1675, the Haudenosaunee had absorbed the Susquehannock to the south and moved westward into the Ohio Valley, where they fought the nations of Illinois and Miami. The Iroquais attempted to expand their territory to the Ohio Country and monopolize the fur trade with European markets. Originally, they were a confederation of the Mohawk, Oneida, Onondaga, Cayuga and Seneca tribes that inhabit the Upstate lands of New York, on the shores of Lake Ontario, east of Lake Champlain and Lake George on the Hudson River and the lower mouth of the St. Lawrence River. The Iroquois Confederacy, led by the Mohawks, mobilized against the Huron, mostly algonquians and Iroquois, and against the related tribes of the Great Lakes region. The Iroquais were supplied with weapons by their Dutch and English trading partners; the Algonquians and Huron were supported by the French, their main trading partner. By the middle of the 17th century, the Haudenosaunee had exhausted the number of beavers in its native country. They have therefore launched a campaign to expand their territory and gain access to new hunting and fishing areas. After Dutch traders on the Hudson River (now in New York) supplied them with firearms, the Haudenosaunee began to exercise its military strength. In 1628 they pushed the Mohicans eastward and in the 1630s the Mohawks began to invade the Algonquins in the Ottawa Valley. In the early 1640s, the Mohawk and Oneida colonies attacked settlements in New France and attacked the Algonquian allies of the St.
Lawrence Valley colony. The French decided to be directly involved in the conflict. The Huron and the Iroquais had between 25,000 and 30,000 members.  The Huron and Susquehannocks formed an alliance against Iroquois aggression in 1647, and their warriors were more numerous. The Huron attempted to break up the Iroquois Confederacy by negotiating a separate peace with the Onondaga and Cayuga tribes, but the other tribes intercepted their messengers and ended negotiations.
