The Monongahela culture were an Iroquoian Native American cultural manifestation of Late Woodland peoples from AD 1050 to 1635 in present-day Western Pennsylvania, western Maryland, eastern Ohio, and West Virginia. The culture was named by Mary Butler in 1939 for the Monongahela River, whose valley contains the majority of this culture's sites.

Ohio is a state in the Midwestern region of the United States. Ohio borders Lake Erie to the north, Pennsylvania to the east, West Virginia to the southeast, Kentucky to the southwest, Indiana to the west, and Michigan to the northwest. Of the 50 U.S. states, it is the 34th-largest by area. With a population of nearly 11.8 million, Ohio is the seventh-most populous and tenth-most densely populated state. Its capital and most populous city is Columbus, with other large population centers including Cleveland, Cincinnati, Dayton, Akron, and Toledo. Ohio is nicknamed the "Buckeye State" after its Ohio buckeye trees, and Ohioans are also known as "Buckeyes". Its flag is the only non-rectangular flag of all U.S. states.
