The Hopewell tradition (also incorrectly called the "Hopewell culture"^{[citation needed]}) is the term used to describe common aspects of the Native American culture that flourished along rivers in the northeastern and midwestern United States from 200 BCE to 500 CE. The Hopewell tradition was not a single culture or society, but a widely dispersed set of related populations. They were connected by a common network of trade routes, known as the Hopewell Exchange System. At its greatest extent, the Hopewell exchange system ran from the Southeastern United States into the southeastern Canadian shores of Lake Ontario. Within this area societies participated in a high degree of exchange with the highest amount of activity along waterways. The Hopewell exchange system received materials from all over the United States. Most of the items traded were exotic materials and were received by people living in the major trading and manufacturing areas. These people then converted the materials into products and exported them through local and regional exchange networks. The objects created by the Hopewell exchange system spread far and wide and have been seen in many burials outside the Midwest.
