Passing coureurs de bois (trappers) in canoes were one thing; fresh-cut log cabins and planted fields were quite another.

The Iroquois called the river the Ohio, meaning “something big.” If relations between the French and English were complex and the rivalries of Europe convoluted, the status of Native Americans along the upper Ohio River was even more so. The dominant power in the region was the Iroquois Confederacy, a union of five nations—the Mohawk, Seneca, Oneida, Onondaga, and Cayuga—that coordinated external relations with other tribes as well as with the French and the English. When these five were joined by the Tuscarora, the empire of the Six Nations stretched from the upper Hudson River westward to the Ohio and was an immense buffer between the French and English frontiers.

As the power of the Iroquois Confederacy grew, it exerted what in European terms might be called a feudal domination over other tribes, including the Mingo, Shawnee, and Delaware. These tribes—some historians have simply lumped them together as the “Ohio Indians”—had generally been pushed westward by European settlements.

Despite numerous pronouncements of neutrality, the Six Nations were constantly wooed by both the French and the English. Historically, the Mohawk along the New York frontier were more likely to trade with and be influenced by the English, while the Seneca along lakes Ontario and Erie were more likely to look north to the French. Neutrality aside, the Six Nations referred to its commercial and strategic relationship with the English as the “Covenant Chain” and maintained a similar relationship with the French.

While generally agreeable to advantageous trading relations, the Iroquois Confederacy, like most Native Americans, came to resist European encroachments that had an air of permanency. Passing coureurs de bois (trappers) in canoes were one thing; fresh-cut log cabins and planted fields were quite another. Of course, the French, whose empire was based largely on a transitory fur trade anchored at a few key points, were of a similar mind. Thus as the dust of Aix-la-Chapelle settled, the French determined to do something about these English incursions into the Ohio Valley and strengthen their relations with the Ohio Indians before it was too late.
