1.2 Native American Societies Before European Contact

Diverse environments, diverse societies

Native American societies adapted to their specific environments, developing distinct economies and cultures. In the Great Plains, groups relied on hunting bison. In the Pacific Northwest, abundant salmon supported permanent villages. In the arid Southwest, peoples like the Pueblo built irrigation systems for farming maize in dry conditions.

Agricultural complexity in the East and Southwest

In the Great Basin and Great Plains, some societies were nomadic, following food sources. In contrast, Mississippian societies in the Ohio and Mississippi River valleys built large, complex settlements like Cahokia, supported by intensive agriculture (maize, beans, squash — the 'Three Sisters'), trade networks, and social hierarchies with chiefs.

Shared traits despite diversity

Despite vast differences, many Native societies shared common features: religious practices tied to land and nature, kinship-based social structures, and elaborate trading networks connecting distant groups. Population estimates before contact ranged widely, but scholars agree millions of people lived across North America, organized into hundreds of distinct linguistic and cultural groups.
