History of Native Americans in the United States

The history of Native Americans in the United States began before the founding of US, tens of thousands of years ago with the settlement of the Americas by the Paleo-Indians. The Eurasian migration to the Americas occurred over millennia via Beringia, a land bridge between Siberia and Alaska, as early humans spread southward and eastward, forming distinct cultures and societies. Archaeological evidence suggests these migrations began 20,000 years ago and continued until around 12,000 years ago, with the earliest inhabitants classified as Paleo-Indians, who spread throughout the Americas, diversifying into numerous culturally distinct nations. Major Paleo-Indian cultures included the Clovis and Folsom traditions, identified through unique spear points and large-game hunting methods, especially during the Lithic stage.

Around 8000 BCE, as the climate stabilized, new cultural periods like the Archaic stage arose, during which hunter-gatherer communities developed complex societies across North America. The Mound Builders created large earthworks, such as at Watson Brake and Poverty Point, which date to 3500 BCE and 2200 BCE, respectively, indicating early social and organizational complexity. By 1000 BCE, Native societies in the Woodland period developed advanced social structures and trade networks, with the Hopewell tradition connecting the Eastern Woodlands to the Great Lakes and the Gulf of Mexico. This period led to the Mississippian culture, with large urban centers like Cahokia—a city with complex mounds and a population exceeding 20,000 by 1250 CE.

From the 15th century onward, European contact drastically reshaped the Americas. Explorers and settlers introduced diseases, causing massive Indigenous population declines, and engaged in violent conflicts with Native groups. By the 19th century, westward U.S. expansion, rationalized by Manifest destiny, pressured tribes into forced relocations like the Trail of Tears, which decimated communities and redefined Native territories. Despite resistance in events like the Sioux Uprising and Battle of Little Bighorn, Native American lands continued to be reduced through policies like the Indian Removal Act of 1830 and later the Dawes Act, which undermined communal landholding.

In the 20th century, Native Americans served in significant numbers during World War II, marking a turning point for Indigenous visibility and involvement in broader American society. Post-war, Native activism grew, with movements such as the American Indian Movement (AIM) drawing attention to Indigenous rights. Landmark legislation like the Indian Self-Determination and Education Assistance Act of 1975 recognized tribal autonomy, leading to the establishment of Native-run schools and economic initiatives. Tribal sovereignty has continued to evolve, with legal victories and federal acknowledgments supporting cultural revitalization.

By the 21st century, Native Americans had achieved increased control over tribal lands and resources, although many communities continue to grapple with the legacy of displacement and economic challenges. Urban migration has also grown, with over 70% of Native Americans residing in cities by 2012, navigating issues of cultural preservation and discrimination. Continuing legal and social efforts address these concerns, building on centuries of resilience and adaptation that characterize Indigenous history across the Americas.
