Common perceptions of American history often anchor on dates like 1776 (Declaration of Independence) and 1492 (Columbus's arrival).
However, true American history begins around 15,000 years ago with the settlement of the Americas by the first peoples.
Diverse and complex native societies existed long before European contact, adapting to their environments.
Arrival of First Peoples
Scholarly Debate: Theories exist regarding the initial migration to the Americas:
Land Bridge Theory: About 12,000 years ago, during an ice age, lowered sea levels may have revealed a land bridge between Asia and the Americas.
Recent archaeological findings suggest that people may have arrived even earlier and could have used boats.
By the late 1400s, estimates suggest around 50 million people lived in the Americas, with 4-6 million residing in North America.
Development of Societies
A significant change occurred around 5000 BCE with the domestication of maize (corn) in Mexico.
Transition from hunter-gatherer societies to settled agricultural communities, allowing the formation of villages and complex societies, although hunting and gathering continued alongside agriculture.
Major Native Societies by Region
Southwest (Example: Ancestral Puebloans)
Adaptation to a dry climate through complex irrigation systems for maize cultivation.
Dwellings often consisted of large cave complexes, supporting greater population densities once agriculture flourished.
Great Plains
Predominantly continued hunting and gathering lifestyle focused on hunting bison with portable dwellings (teepees).
Northwest
Fishing provided abundant food sources; farming led to the establishment of large settlements (e.g., Cahokia).
Cahokia had a population that could reach 25,000-40,000 at its peak.
Mississippian Culture and East Coast Societies
Utilized three-sister farming: planting corn, beans, and squash together.
Benefits include:
Corn provides a trellis for beans.
Squash protects the roots of corn.
This method promoted a nutritious diet and supported a high population density.
Impact of European Contact
By the late 1400s and 1500s, native societies had evolved for over 14,000 years.
The arrival of Europeans brought unprecedented changes, including new pathogens, plants, and animals that drastically altered the Americas and its indigenous populations.
