There is a historical gap between evidence of the end of the Fort Ancient presence in the Waverly area and the beginning of the presence of the Shawnee Native American tribe. It is not known whether the Shawnee were descendants of the Fort Ancient, but there are a number of similarities between the two cultures that have led some to speculate that this is the case. There is also evidence to suggest that Siouan nations such as the Mosopelea may be descendants of the Fort Ancient culture. As European settlements began to push into Ohio country, the Shawnee were driven further and further west, and there is an extensive record of the Shawnee's clashes with settlers, including Tecumseh's War and various battles of the War of 1812.
