3. Early Cultures

Between 35,000 BCE and 10,500 BCE, people from Siberia migrated to North America by crossing the Bering Strait into Alaska, which was dry land during the Ice Age due to lower sea levels. Linguistic evidence suggests they likely arrived in multiple waves, spreading across the continent.

This period, known as the "Paleo-Indian" era, is the longest phase of North American prehistory, lasting from around 35,000 BCE to 8000 BCE (or even 4500 BCE in some areas).

During this time, the indigenous people were hunter-gatherers, primarily focusing on hunting large animals (megafauna) such as woolly mammoths, mastodons, camels, bison, giant sloths, giant beavers, and musk oxen. They also faced dangerous predators like saber-toothed tigers, American lions, and giant short-faced bears. Up until around 9200 BCE, they used wooden spears with fire-hardened tips for hunting and employed stone and bone tools for tasks like chopping and scraping. In addition to hunting, their diet included a variety of wild plants, including seeds, berries, roots, and bulbs.

 3.1. Adena culture

From about 1000 BC some groups began supplementing their hunter-gatherer way of life with small-scale farming. This allowed villages to grow, often semi-permanent in nature: they moved to new locations as local soils became exhausted. The people of the Adena culture, which flourished between 1000 BCE and 200 CE, and which originated in the Ohio Valley before spreading out into neighboring areas, carried on the tradition of mound building – but with a difference. Whereas previously these earthworks seem to have been purely ceremonial, they are now burial mound.

The Adena earthworks were larger and more complex than those of the Poverty Point culture, and this must reflect a more complex society. The grave goods show that some individuals enjoyed higher status and wealth than others.

3.2.  Hopewell culture

As time went by farming became more important to the economy of the people of the eastern woodlands. The Adena culture was eventually displaced by the Hopewell culture, which emerged around 200 BCE and came to an end about 700 CE. This shared many features with the Adena, but on a larger and more sophisticated scale; it also covered a much larger area than the Adena had done.

3.3.Mississippian culture

Eventually the Hopewell culture was succeeded by another, the Mississippian. And just as the Hopewell had been more advanced than the Adena, so the Mississippian was more advanced than the Hopewell.

Whilst the Mississippian culture carried on many of the traditions pioneered by the Adena and Hopewell, it also displayed new features, possibly derived from contact with the Mesoamerican world to the south. Most notably, the Mississippians  constructed  not  just  burial  mounds,  but  temple  mounds  as  well  –  a  strikingly Mesoamerican characteristic.

The Mississippian people's society was the most complex of all the “mound-building” cultures of the eastern woodlands, and was moving towards urbanism. Indeed, their larger settlements, the most famous example being Cahokia, on the banks of the Mississippi, were the size of major European cities of the time, though lacking the density of true urban settlements.

 The Mississippian culture as a whole lasted until just before contact times, though remnants of it, for example amongst the Natchez people, endured into the 18th century.

3.4. Hohokam culture

To the west of the Mogollon, the Hohokam culture developed around 100 BC, exhibiting many similarities to other regional cultures. A key aspect of Hohokam society was their reliance on irrigation-based agriculture. The Hohokam culture abruptly declined around 1500 CE. Their descendants are typically identified as the Akimel O'odham (Pima) and Tohono O'odham (Papago) tribes. The Hohokam culture abruptly declined around 1500 CE.

5.3. Anasazi Culture

The Anasazi culture was the most advanced of the southwestern cultures. It emerged to the north east of the Hohokam culture, and at about the same time as. It was from c. 750 CE, however, that the Anasazi developed a new kind of architecture, the pueblo, for which their descendants are still famous.

As the Anasazi people increasingly established their communities, the production of trade items expanded. They crafted beautiful and practical baskets and sandals. Eventually, they acquired skills to produce and decorate pottery and jewelry. They also discovered how to cultivate cotton and weave it. They also learned how to use the bow and arrow.

 5.4. Post-Anasazi Southwest

The Anasazi culture began to go into decline from about 1300. Many of the survivors moved south and settled in the Rio Grande and Little Colorado valleys. Here they maintained the cultural traditions of the Anasazi and became ancestral to present-day Pueblo peoples such as the Zuni, Keres, Tiwa and Hopi. Most modern pueblos are located on mesa tops. There are also some villages situated in the desert lowlands, or along rivers. These displayed other types of houses – pole-framed huts covered with plant mats or earth.

Maize was the most important of all crops, probably providing more nutrition than all the other crops combined. After maize, the most important food crops were beans and squash. Other crops were not grown for food. Fiber plants such as cotton were a major source of fabrics – only in the southwest of North America were true looms in use. Also, dye plants, ornamental plants, medicinal herbs and stimulants (such as tobacco) were grown.

 Other groups have arrived in the region in more recent times, from c. 1000 CE onwards. These came in from the north, following a nomadic hunter-gatherer lifestyle. Later they took to raiding farming settlements to supplement their diets, and may have played an important part in the decline of the older, more settled cultures. These peoples included the Apache and the Navajo (Dineh). The latter, after contact with the Spanish and their sheep, eventually took to a herding lifestyle.

5.6. Californian cultures

The Californian coast also gave rise to a dense hunter-gatherer-fisher population. This landscape was not as mountainous as the northwest, nor the tree cover as dense (and in the south almost disappears). This made wood resources less available. Though wood plank houses similar to those of the Northwest were by no means unknown, particularly in the north, the inhabitants constructed many other kinds of dwellings as well. Among the most common were cone-shaped structures made from poles, and covered with brush, grass and reeds. There were also domed earth-covered pit-houses.

4. Conclusion

The early history of America, from its prehistoric roots to the colonial era, laid the groundwork for the nation's development. Indigenous cultures demonstrated remarkable adaptability and innovation, while European colonization introduced new social, economic, and political structures. These periods also brought profound challenges, including displacement, conflict, and the establishment of slavery. Understanding this history helps us appreciate the complexities of America's past and its enduring impact on modern society.
