Beginning around 4,000 - 5,000 years ago new features of subsistence, technology, and society began to appear at somewhat different times in different parts of North America. Settlements became larger, and there were more of them. Many settlements were located in ecotones, areas where two or more environments came together. By settling in such prime locations, people could exploit a wider variety of resources without having to relocate their homes. Over time, smaller camps were established in other areas, forming satellite communities. Eventually, each major community was surrounded by peripheral settlements and new forms of social and political relationships emerged, especially non-egalitarian political systems. Accompanying these changes were marked differences in wealth as well as access to goods and services, both within and between communities, resulting in some societies becoming highly stratified, with elites, nobles, commoners, poor, and vagabonds, and in some communities, occupational specialist guilds arose.

Great elaboration of technology
Shortly after 1000 B.C., three important innovations
took hold in many societies in the Eastern Woodlands: pottery manufacture,
deliberate cultivation of native plants, and burials under funerary mounds.
Together, these three innovations launched Native American societies in
the east on a multi-faceted path of cultural change and elaboration, culminating
in the highwater mark societies of the Mississippian cultural tradition.
In eastern North America many groups began to supplement their gathering and hunting diet by the deliberate planting of native plants. The seeds (sunflower, goosefoot, marsh elder, gourd) eventually taken under domestication were collected from wild stands along river floodplains for centuries before they were cultivated deliberately. This development occurred within a number of more-or-less isolated gathering-and-hunting cultures living in small river valleys, with the cultivated plants filling a small niche in an otherwise very diverse diet of wild plant foods, fish, waterfowl, and game animals.
Accompanying the rise of supplementary cultivation and
more intensive exploitation of wild food resources was greater sedentism,
regular social interaction and economic exchange, some degree of social
ranking, and increased ceremonialism, especially surrounding burial and
life after death. Shortly after 3000 years ago, powerful chiefdoms
arose in the midwestern and southeastern parts of the U.S., societies among
whom elaborate burial customs and the building of earthen burial mounds
and earthworks were commonplace (giving rise to the common name "The
Moundbuilders"). The best known of these moundbuilding cultures were
the Adena and Hopewell centered in the Ohio
Valley. The Adena lasted from about 1000 B.C. to A.D. 200; the Hopewell,
from about 300 B.C. to A.D. 700. Although they shared many cultural traits
and coexisted for several centuries, their exact relationship is not known
nor do we know where either of the two cultural systems originated.
Adena
The Adena were gatherers and hunters and also may have
engaged in incipient agriculture - growing sunflowers, pumpkins, gourds,
and goosefoot. But it is their earthworks, found in and around their villages,
that affirm their high degree of social organization. Conical and dome-shaped
burial mounds grew larger and more ambitious over the centuries and towards
the end of Adena times, high mounds were constructed over multiple burials,
with the corpses usually placed in log-lined tombs. The grave goods associated
with burials tells us that there were social inequalities in the culture,
while the raw material from which many of the grave goods were made speaks
to long-distance trading networks.
Hopewell
Hopewell culture sites contain many of the same elements
as the Adena, but were generally on an enhanced scale--more, large earthworks;
richer burials; intensified ceremonialism; greater refinement in art; a
stricter class system and increased division of labor; more agriculture;
a far-flung trading network; and Hopewell-associated sites cover a much
larger territory. The Hopewell, like the Adena, constructed a variety of
earthworks, many covering multiple burials, as well as large geometric earthwork
enclosures.
Mississippian
Around 1200 years ago the focus of power (economic, religious, political)
shifted to the Mississippi Valley and the southeastern part of the U.S.
with the rise of the Mississippian tradition, fostered in
part by the introduction and widespread cultivation of maize &beans
that helped support higher population densities and more complex social
&economic &political organizations.
The Mississippian tradition represents the highwater
mark of eastern North American Indian civilizations. Like their predecessors,
the Adena &Hopewell, the Mississippian people relied heavily on seasonal
crops of nuts, fruits, berries, &seed-bearing plants as well as hunting
turkey, migratory waterfowl, &deer. But they were primarily agriculturalists,
raising maize, squashes, &beans. This new subsistence pattern transformed
society. Settlements became more complex with formal layouts of house groupings
around open plazas and large earthen platform mounds. Society became more
hierarchical as powerful religious &secular elites emerged.
In the southwestern region of what is now the U.S.,
similar agricultural societies were emerging. Maize agriculture reached
this area from Mexico sometime aroud 3200 years ago and by 2300 years ago
sedentary farming villages were scattered throught the region, eventually
giving rise to the several great southwestern farming based traditions including:
Hohokam, Mogollon, Anasazi, and Salado.
Hohokam
The Hohokam tradition emerged between 2000 and 1500
years ago in central and southern Arizona and lasted until about 450 - 500
years ago. When archaeologists first excavated Hohokam settlements they
believed that the people were immigrants from northern Mexico who brought
their extensive irrigation agriculture, ball courts, and earthen platform
mounds with them. This scenario is no longer believed. Instead, the Hohokam
tradition is now seen as an indigenous development from local populations
who enjoyed complex trading &ceremonial relationships with people all
over the southwest and northen Mexico, borrowing ideas &items of material
culture when it suited them and blending them with their own to create a
vibrant culture.
Hohokam subsistence was based on maize, beans, gourds,
cotton, &other crops, as well as on gathering. Crops were planted to
coincide with the semiannual rainfall &flooding patterns, cultivating
floodplains &catching runoff from local storms with dams, terraces,
&other water catchment devices. They also practiced irrigation from
flowing streams, building canals (some as much as 10-15 kilometers long)
to carry water from streams and rivers to their fields.
Mogollon
The Mogollon tradition emerged from Archaic roots between
2300 &1800 years ago &lasted until between 1200 &550 years ago
when it became part of the Anasazi tradition. Centered in western New Mexico,
the Mogollon was an agricultural tradition in which gathering &hunting
were always important. Unlike the Hohokam who depended extensively on irrigation
and water catchment devices, Mogollon agriculture was primarily rainfall
based.
Anasazi
The best known &most intensively studied of the
three archaeological traditions of the southwestern U.S. is the Anasazi,
believed by most archaeologists to be ancestral to the cultures of the various
Puebloan nations: the Hopi, the Zuni, and those groups living along the
upper reaches of the Rio Grande River in New Mexico. Like the Hohokam &Mogollon,
Anasazi roots lie in Archaic cultures that flourished in &around the
Four Corners area where Arizona, New Mexico, Colorado, &Utah meet. Even
after taking up maize agriculture seriously some 1600 years ago, the Anasazi
still made heavy use of wild vegetable foods. Like the Hohokam, they also
used irrigation and water impoundment techniques where practicable, but
most of their farming depended on dry agriculture &seasonal rainfall.
Before 1200 years ago, the Anasazi lived in semi-subterranean pithouses.
But shortly thereafter, the basic Anasazi settlement pattern evolved and
above-the-ground houses were substituted for the pithouses, which developed
into kivas,
subterranean ceremonial structures found in every large village. By 1000
years ago, large settlements of contiguous dwellings (which the Spanish
called "pueblos") became the rule with clusters of rooms serving
as homes for separate families or lineages. Around 900 years ago, the population
congregated in fewer but larger pueblos located in densely populated areas
with some pueblos located under cliff overhangs, the so-called cliff dwellings.
It was around this time that the so-called "great houses" developed.
One of these, Pueblo Bonito (pictured above), was a huge D-shaped structure
of 800 rooms rising several stories. Within the pueblo were large open courtyards
and several kivas, one of which was 60 feet in diameter with wide masonry
benches encircling the interior.
