The Hopewell culture was a Native American culture from prehistoric North America. It was centered mainly in what is now the Midwest of the United States, though its influence was felt in many other areas because of trading networks. The Hopewell are believed to have been in existence from around 200 BCE until 500 CE. The best known remains of the Hopewell culture are the earthen mounds that they built in various places across the Midwest. Many of these mounds held burials which are the major source of artifacts that give us what information we have about this culture.
