Moundbuilder societies

Moundbuilder societies were ancient Native American cultures known for constructing large earthen mounds across North America, especially in the Ohio River Valley and southeastern U.S. They flourished from about 1000 BCE to 1700 CE. These mounds served various purposes, including religious ceremonies, burial sites, and social or political gatherings. Notable groups include the Adena, Hopewell, and Mississippian cultures. The mounds demonstrate their advanced societal organization, craftsmanship, and spiritual practices. The societies declined or transformed before European contact, leaving behind a significant archaeological legacy that helps us understand early Native American achievements.
