Mississippian culture
Culture | Defunct
800 CE to 1600 CE
The Mississippian culture is a mound-building Native American culture that flourishes in what is now the Midwestern, Eastern, and Southeastern United States from approximately 800 to 1500 CE, varying regionally.
The Mississippian way of life began to develop in the Mississippi River Valley (for which it is named).
Cultures in the tributary Tennessee River Valley may have also begun to develop Mississippian characteristics at this point.
Almost all dated Mississippian sites predate the de Soto expedition of 1539-40, with notable exceptions being Natchez communities that maintain Mississippian cultural practices into the 18th century.

Long-Term Significance
By CE 819, Gulf and Western North America was a mosaic of interconnected cultures ranging from agricultural chiefdoms to mobile hunter-gatherers, linked by complex trade and communication networks spanning coasts, deserts, and river valleys.
Maize had been a minor crop in the Woodland Period, but many archaeologists believe new varieties of maize were introduced to the region that produced higher yields, allowing for a population boom.
This increase in population, combined with the potential for surplus and growing tensions over control of territory, appears to have led to large nucleated settlements throughout the eastern United States.
Although this manifested itself earliest along the Mississippi south of Iowa, the earliest Late Prehistoric cultures appeared in the western part of the state.

The Middle Mississippi peoples who succeeded the Woodland culture construct huge earthen mounds by 900, and develop complex urban areas in the region of present Illinois.
Several hundred of the so-called Mississippian societies appear by 900 in the Mississippi Valley and its major tributaries, stretching from Saint Louis, Missouri to …
…Vicksburg, Mississippi.
The basis of the Mississippian economy has largely shifted from hunting and gathering to intensive maize cultivation by 900.
Mississippian house forms have gradually become rectangular; some villages possess stockades or fortifications.

Spiro Mounds, near the modern town of Spiro in eastern Oklahoma, is the site of a series of twelve earthen burial mounds associated with the Mississippian tradition of the Mound Builders, who begin constructing mounds there in about 1000.
Inhabited from 850, Spiro is the westernmost outpost of the Mississippian culture that has spread along the lower Mississippi drainage area and its tributaries.
The vast Mississippian trading network brings obsidian from Mexico, colored flint from New Mexico, copper from the Great Lakes, mica from the Carolinas, and conch shells from the Gulf Coast.
The engravings of humans, animals, and geometric designs on the conch shells at Spiro are particularly well rendered and undoubtedly had profound symbolic significance.
The Spiro's ceremonial objects are some of the most sophisticated artforms ever found in the Mississippian region.
