River Seine (Cahokia as a significant urban center)

The River Seine was a crucial trade route in ancient North America, especially around Cahokia, a major pre-Columbian city located near present-day St. Louis. Cahokia, thriving from about 1050 to 1350 AD, was one of the largest and most influential urban centers of its time, with a population estimated at tens of thousands. Its location near the Mississippi and surrounding waterways allowed for the efficient movement of goods, people, and ideas, helping it become a powerful political and cultural hub. Cahokia’s impressive earthworks and complex society highlight its importance in regional trade networks and urban development.
