Repercussions

The commercial extermination of the American bison was not an accident — it was explicit policy. General Philip Sheridan endorsed it as the fastest way to destroy the economic and cultural foundation of Plains life. From an estimated 30–60 million animals in 1800, the southern herd was virtually gone by 1878 and the northern herd by 1883. Hunters killed millions of animals solely for their hides, leaving carcasses to rot across the Plains. Without the buffalo, Plains nations faced starvation, loss of shelter materials, loss of trade goods, and the destruction of a spiritual relationship that had defined their cultures for thousands of years. The U.S. Congress twice passed bills to protect the buffalo; President Grant refused to sign them. The extermination was the single most decisive factor in breaking armed Native resistance.

Beginning with the Fort Laramie Treaty of 1851 and accelerating through the 1860s and 1870s, the United States systematically confined Native nations to reservations — parcels of land vastly reduced from traditional territories, chosen for their marginal agricultural value and distance from settler populations. Reservations were frequently located on land unsuited for farming, the lifestyle the government simultaneously demanded. Rations promised by treaty were chronically underfunded, fraudulently distributed, and deliberately kept inadequate to create dependency. Reservation agents wielded enormous power and often used it corruptly. The reservation system was designed not merely to confine but to transform — to break communal land use, traditional governance, extended family structures, and spiritual practice.

The General Allotment Act of 1887, known as the Dawes Act, was the legislative capstone of the assimilation era. It broke up tribally held reservation land into individual 160-acre allotments assigned to Native heads of household, with 'surplus' land — often the majority — opened to white settlement. The stated goal was to turn Native people into individual farmers on the American model. The effect was catastrophic: Native landholdings fell from 138 million acres in 1887 to 48 million acres by 1934. The communal land base that had sustained tribes was fragmented and sold. Traditional governance structures, which depended on collective land stewardship, were undermined. 'Friends of the Indian' reformers who supported the Dawes Act believed they were helping; they were instead completing the dispossession that warfare had begun.

Captain Richard Pratt founded the Carlisle Indian Industrial School in Pennsylvania in 1879 on the explicit principle of 'Kill the Indian, save the man.' Children — sometimes as young as five — were forcibly removed from their families, transported hundreds of miles away, forbidden to speak their languages, forced to wear Western clothing, given English names, and punished for any expression of traditional culture. By 1900, over 20,000 Native children attended boarding schools. Physical, emotional, and sexual abuse was widespread. Children died of disease and despair; many were buried far from home in school cemeteries. The schools systematically severed the transmission of language, ceremony, kinship structures, and cultural knowledge between generations. A 2022 U.S. government report identified over 50 burial sites at former boarding schools.

The Ghost Dance movement, founded by the Paiute prophet Wovoka in 1889, spread rapidly across reservation communities as a response to the devastation of the preceding decades. Wovoka preached that righteous living, the Ghost Dance, and rejection of white ways would bring about a restoration of the old world — the return of the ancestors, the buffalo, and Indigenous sovereignty. The movement was explicitly peaceful; Wovoka himself counseled non-violence. Reservation agents and the Army interpreted it as a threat and mobilized troops across the Plains. The military response — 3,000 troops deployed in the fall of 1890 — directly caused the killing of Sitting Bull and set in motion the events leading to Wounded Knee. The Ghost Dance was suppressed by force, but its spiritual descendants persisted in the 20th century's Indigenous renewal movements.

Manifest Destiny — the belief that the United States was divinely ordained to expand across the entire continent — provided the moral and political framework for the dispossession of Native peoples. Coined by journalist John O'Sullivan in 1845, the concept fused religious determinism, racial hierarchy, and political ambition into an ideology that made conquest feel inevitable and righteous rather than chosen and violent. It allowed Americans to regard the Plains Wars not as wars of aggression against people defending their homelands, but as the natural unfolding of civilization over savagery. This ideology shaped policy, journalism, popular culture, and the self-understanding of soldiers in the field. Its legacy persists in how American history has traditionally been taught — as a story of expansion and progress rather than of dispossession and destruction.

The 1890 U.S. Census contained a single line that historian Frederick Jackson Turner would immortalize in his 1893 'Frontier Thesis': the American frontier — defined as a line of settlement beyond which population density fell below two persons per square mile — no longer existed. The frontier was, officially, closed. Turner argued that the frontier had been the defining force in American democracy, forging self-reliance and individualism. What the Census did not say was that the closing of the frontier had required the confinement of the Native peoples who had lived on that land for millennia. The same decade that marked the 'closing' saw the Dawes Act strip millions of acres of Native land, the Wounded Knee Massacre kill hundreds, and the boarding school system accelerate the destruction of Indigenous cultures.

Of the approximately 300 distinct Native languages spoken in North America at European contact, fewer than half survived into the 20th century, and most of those were critically endangered. The boarding school system was the primary mechanism of language destruction — children punished for speaking their mother tongues across generations severed the chain of transmission. With language went ceremony, oral history, ecological knowledge, relationship networks, legal traditions, and the particular ways of understanding the world embedded in each tongue. The loss was not incidental but deliberate: assimilation policy explicitly targeted language as the carrier of cultural resistance. Language revitalization has become one of the central projects of 21st-century Indigenous communities, with immersion schools, recording projects, and community programs working against time as the last fluent speakers age.

Native resistance to dispossession never stopped — it transformed. The Society of American Indians (1911), the National Congress of American Indians (1944), and the American Indian Movement (1968) represented successive generations of organized Indigenous political advocacy. The Indian Citizenship Act of 1924 granted citizenship but not full rights. The Indian Reorganization Act of 1934 reversed some Dawes Act damage. The Civil Rights era saw an explosion of Native activism: the occupation of Alcatraz (1969-71), the Trail of Broken Treaties (1972), and the occupation of Wounded Knee (1973) by AIM brought national attention to reservation conditions. Legal victories followed: the Indian Self-Determination Act (1975), the American Indian Religious Freedom Act (1978), and the Native American Graves Protection and Repatriation Act (1990) recognized rights long denied. The movement continues today in fights for water rights, land rights, sacred site protection, and the return of ancestral remains.

The Indian Reorganization Act of 1934 — the 'Indian New Deal' under Commissioner John Collier — ended the Dawes Act allotment policy, restored some tribal lands, and formally recognized tribal self-governance. But the path to genuine sovereignty has been long and contested. Termination policy in the 1950s attempted to dissolve tribal status entirely for dozens of nations. Court battles over treaty rights — fishing, hunting, water — have continued for more than a century. The Violence Against Women Act's tribal jurisdiction provisions (2013, 2022) addressed the catastrophic rates of violence against Indigenous women on reservations. The Missing and Murdered Indigenous Women crisis, disproportionate rates of poverty, suicide, and disease on reservations, and the ongoing struggle for recognition of treaty rights all trace directly to the policies and wars of the 19th century. Federal recognition remains incomplete: over 400 tribal nations are federally recognized; many more are not.
