and into the American Southeast. Also, Iroquoian expansions to the northeast of the Fort Ancients brought new Algonquian & Iroquoian neighbors into their region. We also see the Fort Ancients begin to borrow heavily from almost every culture with whom they interacted. Eastern Fort Ancients were amalgamating a mound burial with Iroquoian techniques of defleshing the dead & urn burials. Mississippian influence came up from the south. In western Ohio, there is even heavy evidence that they took on the Algonquian Green Corn Ceremony, in which part of the unripened corn crop was "sacrificed" by burning and its ashes were used to re-fertilize the fields. Around 1300, however, it appears that Mound burials were replaced entirely by the Eastern Siouan tradition of under-the-home burials (This custom also entered Monongahela society). Late phase (approx. 1450-1750 CE) Here, Fort Ancient culture was at its height. Only one known Fort Ancient tribe has been verified by name in the historical record—the Mosopelea, presumably of southeast Ohio. There is also a chance that a Siouan people called the Keyauwee, who appear alongside the Tutelo (an Eastern Siouan tribe from West Virginia) in North Carolina around 1700 could also have been of Fort Ancient stock. During the French explorations, a Ho-chunk native named Tonti told them that these people had been known as the Chonque. Mosopelea language is marked as being the only known Siouan tongue to use the "f" sound, which is far more common among the Muskogean languages of the Mississippians. Despite no historical accounts of contact existing, we see a remarkable amount of European made goods from Fort Ancient sites—including brass and steel items, as well as glassware. They even melted down old or broken goods and reforged them into new items. No single gun part has yet been discovered in conjunction with a Fort Ancient site. The Fort Ancients were heavily affected by European disease, as well as the Beaver Wars period. Carbon dating seems to dictate that they were wiped out, not altogether, but in waves. The most recent of all surviving sites date from Northern Kentucky alone—these being any from 1680 and on. There have been no real French accounts brought forward detailing contact, as they arrived in the region at that time, however the French did note that most of both sides of the Ohio River Valley was covered in similar styled villages in various states of destruction
