Enormous changes affected the inhabitants of the Eastern Woodlands area during the eleventh through fifteenth centuries AD. At this time many groups across this area (known collectively to archaeologists as Oneota) were aggregating and adopting new forms of material culture and food technology. This same period also witnessed an increase in intergroup violence, as well as a rise in climatic volatility with the onset of the Little Ice Age. In "Indigenous Life around the Great Lakes," Richard W. Edwards explores how the inhabitants of the western Great Lakes region responded to the challenges of climate change, social change, and the increasingly violent physical landscape.
