Adena culture: The Adena culture was a Native American culture that existed from 1000 BCE to 200 BCE, in a time known as the Early Woodland period. The Adena culture refers to what were probably a number of related Native American societies sharing a burial complex and ceremonial system.
Coles Creek culture: The Coles Creek culture is an indigenous development of the Lower Mississippi Valley that took place between the terminal Woodland period and the later Plaquemine culture period. The period is marked by the increased use of flat-topped platform mounds arranged around central plazas, more complex political institutions, and a subsistence strategy still grounded in the Eastern Agricultural Complex and hunting rather than on the maize plant as would happen in the succeeding Plaquemine Mississippian period. The culture was originally defined by the unique decoration on grog-tempered ceramic ware by James A. Ford after his investigations at the Mazique Archeological Site. He had studied both the Mazique and Coles Creek Sites, and almost went with the Mazique culture, but decided on the less historically involved sites name. It is ancestral to the Plaquemine culture. Hohokam culture Edit
Hohokam culture: The Hohokam was a culture centered along American Southwest.The early Hohokam founded a series of small villages along the middle Gila River. They raised corn, squash and beans. The communities were located near good arable land, with dry farming common in the earlier years of this period.[19] They were known for their pottery, using the paddle-and-anvil technique. The Classical period of the culture saw the rise in architecture and ceramics. Buildings were grouped into walled compounds, as well as earthen platform mounds. Platform mounds were built along river as well as irrigation canal systems, suggesting these sites were administrative centers allocating water and coordinating canal labor. Polychrome pottery appeared, and inhumation burial replaced cremation. Trade included that of shells and other exotics. Social and climatic factors led to a decline and abandonment of the area after 1400 CE.
Ancestral Puebloan culture: The Ancestral Puebloan culture covered present-day Four Corners region of the United States, comprising southern Utah, northern Arizona, northwestern New Mexico, and southwestern Colorado.[20] It is believed that the Ancestral Puebloans developed, at least in part, from the Oshara Tradition, who developed from the Picosa culture. They lived in a range of structures that included small family pit houses, larger clan type structures, grand pueblos, and cliff sited dwellings. The Ancestral Puebloans possessed a complex network that stretched across the Colorado Plateau linking hundreds of communities and population centers. The culture is perhaps best known for the stone and earth dwellings built along cliff walls, particularly during the Pueblo II and Pueblo III eras. Three UNESCO World Heritage Sites located in the United States are credited to the Pueblos: Mesa Verde National Park, Chaco Culture
Mississippian culture: The Mississippian culture which extended throughout the Ohio and Mississippi valleys and built sites throughout the Southeast, created the largest earthworks in North America north of Mexico, most notably at Cahokia, on a tributary of the Mississippi River in present-day Illinois.
Iroquois culture: The Iroquois League of Nations or "People of the Long House", based in present-day upstate and western New York, had a confederacy model from the mid-15th century. It has been suggested that their culture contributed to political thinking during the development of the later United States government. Their system of affiliation was a kind of federation, different from the strong, centralized European monarchies.
