5th Millennium BCE in North American History

The 5th millennium BCE in North American history provides a timeline of events occurring within the North American continent from 5000 BCE through 4001 BCE in the Gregorian calendar. This time period (from 5000 BCE-4001 BCE) is known as the Middle Archaic. Although this timeline segment may include some European or other world events that profoundly influenced later American life, it focuses on developments within Native American communities. The archaeological records supplements indigenous recorded and oral history.

Because of the inaccuracies inherent in radiocarbon dating and in interpreting other elements of the archaeological record, most dates in this timeline represent approximations that may vary a century or more from source to source. The assumptions implicit in archaeological dating methods also may yield a general bias in the dating in this timeline.
