Edited sentence: Benjamin Drake, writing in 1848, records that the Michigamie, along with the other bands in the Illinois Confederation, had been attacked by a general confederation of the Sauk, Fox, Sioux, Chippewa, Ottawa, and Potawatamies, along with the Cherokee and Choctawa from the south.In the 17th century, the Illinois suffered from a combination of exposure to Eurasian  infectious diseases, to which they had no natural immunity, and warfare by the expansion of the Iroquois into the western Great Lakes region.Many of the Illinois migrated to present-day eastern Kansas to escape the pressure from other tribes and encroaching European settlers.The Iroquois had hunted out their traditional lands and sought more productive hunting and trapping areas (see, Beaver Wars).They sought furs to purchase European goods in the fur trade
