9th millennium BC in North American history
The 9th millennium BC in North American history provides a time line of events occurring within the present political boundaries of United States (including territories) from 9000 BC through 8001 BC in the Gregorian calendar. Although this time line segment may include some European or other world events that profoundly influenced later American life, it focuses on developments within Native American (and Polynesian) communities.
