The Miamis, the most powerful of the confederates, were subdivided into the Eel Rivers, the Weas, and the Piankeshaws. The Kickapoos, a small tribe which lived on the Sangamon, and the Vermilion of the Wabash, were associated generally with the Potawatomi, and were always the allies of the English. The Winnebagoes of Wisconsin were of the linguistic family of the Sioux; were generally associated with the confederates against the Americans, and many of their distinguished warriors fought against General Harrison at Tippecanoe. The decadent tribes known in early times as the Illinois, did not play a conspicuous part in the history of the northwest. While the limits of the various tribes may not be fixed with precision, and the boundary lines were often confused, still there were well recognized portions of the northwest that were under the exclusive control of certain nations, and these nations were extremely jealous of their rights, as shown by the anger and resentment of the Miamis at what they termed as the encroachment of the Potawatomi at the Treaty of Fort Wayne, in 1809. The Wyandots, for instance, were the incontestable owners of the country between the Cuyahoga and the Au Glaize, in the present state of Ohio, their dominion extending as far south as the divide between the waters of the Sandusky river and the Scioto, and embracing the southern shore of Lake Erie from Maumee Bay, to the mouth of the Cuyahoga. Large numbers of them were also along the northern shores of Lake Erie, in Canada. Their territory at one time probably extended much farther south toward the Ohio, touching the lands of the Miamis on the west, but certainly embracing parts of the Muskingum country, to which they had invited the ancient Delawares, respectfully addressed by them as "grandfathers." Intermingled with the Wyandots south and west of Lake Erie were scattered bands of Ottawas, but they were tenants of the soil by sufferance, and not as of right.
