Ohio Hopewell

The Hopewell tradition (also called the Hopewell culture) describes the common aspects of the Native American culture that flourished along rivers in the northeastern and midwestern United States from 200 BC to 500 AD, in the Middle Woodland period. 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 as far south as the Crystal River Indian Mounds into the southeastern Canadian shores of Lake Ontario in the north. 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 what is now 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.

Although the origins of the Hopewell are still under discussion, the Hopewell culture can also be considered a cultural climax.

Hopewell populations originated in western New York and moved south into Ohio, where they built upon the local Adena mortuary tradition. Or, Hopewell was said to have originated in western Illinois and spread by diffusion ... to southern Ohio. Similarly, the Havana Hopewell tradition was thought to have spread up the Illinois River and into southwestern Michigan, spawning Goodall Hopewell. (Dancey 114)
