What it IS: An analysis of how conquest functioned in practice
Key premise: Battles matter as moments that reveal larger strategies—but policy, environment, law, and culture ultimately proved more decisive.
Political, Social, and Economic Systems
Native nations governed themselves independently with their own laws, leadership structures, and diplomatic relations. They made treaties as equals with European powers and the U.S. government—evidence that even the U.S. recognized their political legitimacy.
Key point: U.S. officials often misread decentralized authority as political weakness rather than structural difference.
Plains economies organized around:
Wealth and status tied to kinship, mobility, and animals—NOT land ownership
The buffalo provided virtually everything Plains peoples needed:
This is why destroying the buffalo was such an effective weapon of conquest.
Women exercised substantial influence through kinship networks and marriage alliances
To dismantle these societies, the United States did not simply need military victory—it needed to undermine the ecological, economic, and social foundations of Native autonomy.
This explains why conquest took so many forms beyond battlefield combat.
When Battles Matter—and When They Don't
Native resistance failed not due to lack of courage—but due to asymmetries in logistics, population, and environmental control.
Battles punctuate the story, but policy finishes it.
On June 25–26, 1876, Lakota, Northern Cheyenne, and Arapaho forces defeated the U.S. Army’s 7th Cavalry under Lt. Col. George A. Custer near the Little Bighorn River in present-day Montana.
The battle grew out of the Great Sioux War (1876–77), sparked in part by U.S. efforts to force Lakota people onto reservations and seize the Black Hills after gold was discovered there.
Why it shocked Americans: Custer and over 200 soldiers were killed—an unexpected defeat that dominated national headlines.
Historical significance: The victory demonstrated the real strength of Indigenous resistance, but it also helped justify a major U.S. escalation—more troops, intensified campaigns, and increased pressure that pushed many Native communities onto reservations within a few years.
On December 29, 1890, U.S. soldiers massacred approximately 250-300 Lakota men, women, and children at Wounded Knee Creek, South Dakota.
The Lakota were being disarmed after practicing the Ghost Dance—a spiritual movement promising renewal. The military interpreted religious practice as military threat.
Historical significance: Marks the violent end of organized armed resistance on the Plains and coincides with intensified assimilation efforts.
Economic and Ecological Warfare
Destroyed the foundation of Plains economies
Transformed the Great Plains environment
Eliminated sacred and ceremonial center of life
Where military conquest proved costly or incomplete, environmental destruction succeeded.
Many historians describe this as genocide
Historian Benjamin Madley documents that California's Indigenous population fell from approximately 150,000 in 1846 to 30,000 by 1873—an 80% decline in less than 30 years.
This included:
Madley's book is titled An American Genocide (2016)—the scholarly consensus increasingly supports this characterization.
Why did U.S. officials and commercial interests systematically destroy the buffalo herds?
Containment and Dependency
Dependency was not an accident but a structural feature. Reservations were designed to manage Native peoples, not preserve Native cultures.
Results: Native land holdings fell from 138 million acres in 1887 to 48 million acres by 1934
Founded by the Paiute prophet Wovoka around 1889, the Ghost Dance spread rapidly among Plains peoples experiencing devastation from conquest.
Core beliefs:
This was a peaceful religious movement—the violence came entirely from the U.S. military's response.
Conquest operated through multiple mechanisms:
