The Hopewell tradition, also called the Hopewell culture and Hopewellian exchange, describes a network of precontact Native American cultures that flourished in settlements along rivers in the northeastern and midwestern Eastern Woodlands from 100 BCE to 500 CE, in the Middle Woodland period. The Hopewell tradition was not a single culture or society but a widely dispersed set of populations connected by a common network of trade routes.
