The “Indian wars,” so mythologized in western folklore, were a series of sporadic, localized, and often brief engagements between U.S. military forces and various Native American groups. The more sustained and more impactful conflict, meanwhile, was economic and cultural. The vast and cyclical movement across the Great Plains to hunt buffalo, raid enemies, and trade goods was incompatible with new patterns of American settlement and railroad construction. Thomas Jefferson’s old dream that Indian groups might live isolated in the West was, in the face of American expansion, no longer a viable reality. Political, economic, and even humanitarian concerns intensified American efforts to isolate Indians on reservations. Although Indian removal had long been a part of federal Indian policy, following the Civil War the U.S. government redoubled its efforts. If treaties and other forms of persistent coercion would not work, more drastic measures were deemed necessary. Against the threat of confinement and the extinction of traditional ways of life, Native Americans battled the American army and the encroaching lines of American settlement.

In one of the earliest western engagements, in 1862, while the Civil War still consumed the nation, tensions erupted between Dakota Sioux and white settlers in Minnesota and the Dakota Territory. The 1850 U.S. census recorded a white population of about 6,000 in Minnesota; eight years later, when it became a state, it was more than 150,000. The influx of American farmers pushed the Sioux to the breaking point. Hunting became unsustainable and those Sioux who had taken up farming found only poverty. Starvation wracked many. Then, on August 17, 1862, four young men of the Santee band of Sioux killed five white settlers near the Redwood Agency, an American administrative office. In the face of an inevitable American retaliation, and over the protests of many members, the tribe chose war. On the following day, Sioux warriors attacked settlements near the Agency. They killed 31 men, women and children. They then ambushed a U.S. military detachment at Redwood Ferry, killing 23. The governor of Minnesota called up militia and several thousand Americans waged war against the Sioux insurgents. Fighting broke out at New Ulm, Fort Ridgely, and Birch Coulee, but the Americans broke the Indian resistance at the Battle of Wood Lake on September 23, ending the so-called Dakota War, also known as the Sioux Uprising.

Buffalo Soldiers, the nickname given to African-American cavalrymen by the native Americans they fought, were the first peacetime all-black regiments in the regular United States army. These soldiers regularly confronted racial prejudice from other Army members and civilians, but were an essential part of American victories during the Indian Wars of the late nineteenth and early twentieth centuries. “[Buffalo soldiers of the 25th Infantry, some wearing buffalo robes, Ft. Keogh, Montana] / Chr. Barthelmess, photographer, Fort Keogh, Montana,” 1890. Library of Congress.

More than two thousand Sioux had been taken prisoner during the fighting. Many were tried at federal forts for murder, rape, and other atrocities. 303 were found guilty and sentenced to hang, but at the last moment President Lincoln commuted all but 38 of the sentences. Terrified Minnesota settlers and government officials insisted not only that the Sioux lose much of their reservations lands and be removed further west, but that those who had fled be hunted down and placed on reservations as well. On September 3, 1863, after a year of attrition, American military units surrounded a large encampment of Dakota Sioux. American troops killed an estimated 300 men, women, and children. Dozens more were taken prisoner. Troops spent two days burning winter food and supply stores, all to pacify the Sioux resistance. Conflict still smoldered for decades.Further south, tensions flared in Colorado. In 1851, the Treaty of Fort Laramie had secured right-of-way access for Americans passing through on their way to California and Oregon. But a gold rush in 1858 drew approximately 100,000 white goldseekers and they demanded new treaties be made with local Indian groups to secure land rights in the newly created Colorado Territory. Cheyenne bands splintered over the possibility of signing a new treaty that would confine them to a reservation. Settlers, already wary of raids by powerful groups of Cheyennes, Arapahos, and Comanches, meanwhile read in their local newspapers sensationalist accounts of the Sioux uprising in Minnesota. Militia leader John M. Chivington warned settlers in the summer of 1864 that the Cheyenne were dangerous savages, urged war, and promised a swift military victory. Sporadic fighting broke out. Although Chivington warned of Cheyenne savagery, the aged Cheyenne chief Black Kettle, believing that a peace treaty would be best for his people, traveled to Denver to arrange for peace talks. He and his followers traveled toward Fort Lyon in accordance with government instructions but on November 29, 1864, Chivington ordered his seven hundred militiamen to move on the Cheyenne camp near Fort Lyon at Sand Creek. The Cheyenne tried to declare their peaceful intentions but Chivington’s militia cut them down. It was a slaughter. Black Kettle and about two hundred other men, women, and children were killed.

The Sand Creek Massacre was a national scandal, alternately condemned and applauded. News of the massacre reached other native groups and the American frontier erupted into conflict. Americans pushed for a new “peace policy.” Congress, confronted with these tragedies and further violence, authorized in 1868 the creation of an Indian Peace Commission. The commission’s study of American Indian decried prior American policy and galvanized support for reformers. After the inauguration of Ulysses S. Grant the following spring, Congress allied with prominent philanthropists to create the Board of Indian Commissioners, a permanent advisory body to oversee Indian affairs and prevent the further outbreak of violence. The Board effectively Christianized American Indian policy. Much of the reservation system was handed over to Protestant churches, which were tasked with finding agents and missionaries to manage reservation life. Congress hoped that religiously-minded men might fare better at creating just assimilation policies and persuading Indians to accept them. Historian Francis Paul Prucha believed that this attempt at a new “peace policy… might just have properly been labelled the religious policy.” Many female Christian missionaries played a central role in cultural re-education programs that attempted to not only instill Protestant religion but also impose traditional American gender roles and family structures. They endeavored to replace Indians’ tribal social units with small, patriarchal households. Women’s labor became a contentious issue, for very few tribes divided labor according to white middle-class gender norms. Fieldwork, the traditional domain of white males, was primarily performed by native women, who also usually controlled the products of their labor, if not the land that was worked, giving them status in society as laborers and food providers. For missionaries, the goal was to get Native women to leave the fields and engage in more proper “women’s” work–housework. Christian missionaries performed much as secular federal agents had. Few American agents could meet Native Americans on their own terms. Most viewed reservation Indians as lazy and thought of Native cultures as inferior to their own. The views of J. L. Broaddus, appointed to oversee several small Indian tribes on the Hoopa Valley reservation in California, are illustrative: in his annual report to the Commissioner of Indian Affairs for 1875, he wrote, “the great majority of them are idle, listless, careless, and improvident. They seem to take no thought about provision for the future, and many of them would not work at all if they were not compelled to do so. They would rather live upon the roots and acorns gathered by their women than to work for flour and beef.”

In 1874, Quanah Parker (of Comanche and English-American ancestry) led a Comanche war party into northern Texas to avenge their slain relatives. This failed attempt led to the reversal of federal policy in Washington, and eventually depleted the food source and economic livelihood of the Comanches. Parker afterwards became chief over all Comanches on the newly settled Oklahoma reservation, and, through smart investing, soon was the single richest native American of the late nineteenth century.

If the Indians could not be forced through kindness to change their ways, most agreed that it was acceptable to use force, which native groups resisted. In Texas and the Southern Plains, the fierce Comanche, Kiowa, and their allies had wielded enormous influence. The Comanche in particular controlled huge swaths of territory and raided vast areas, inspiring terror from the Rocky Mountains to the interior of Northern Mexico to the Texas Gulf Coast. But after the Civil War, the U.S. military refocused its attention on the Southern Plains.

The American military first sent messengers to the Plains to find the elusive Comanche bands and ask them to come to peace negotiations at Medicine Lodge Creek in the fall of 1867. But terms were muddled: American officials believed that Comanche bands had accepted reservation life, while Comanche leaders believed they were guaranteed vast lands for buffalo hunting. Comanche bands used designated reservation lands as a base from which to collect supplies and federal annuity goods while continuing to hunt, trade, and raid American settlements in Texas.

Confronted with renewed Comanche raiding, particularly by the famed war leader Quanah Parker, the U.S. military finally proclaimed that all Indians who were not settled on the reservation by the fall of 1874 would be considered “hostile.” The Red River War began when many Comanche bands refused to resettle and the American military launched expeditions into the Plains to subdue them, culminating in the defeat of the remaining roaming bands in the canyonlands of the Texas Panhandle. Cold and hungry, with their way of life already decimated by soldiers, settlers, cattlemen, and railroads, the last free Comanche bands were moved to the reservation at Fort Sill, in what is now southwestern Oklahoma.

On the northern Plains, the Sioux people had yet to fully surrender. Following the troubles of 1862, many bands had signed treaties with the United States and drifted into the Red Cloud and Spotted Tail agencies to collect rations and annuities, but many continued to resist American encroachment and a large number of Sioux refused to sign and remained fiercely independent. These “non-treaty” Indians, such as those led by famous chiefs Sitting Bull and Crazy Horse, saw no reason to sign treaties that they believed would not be fully honored.

Then, in 1874, an American expedition to the Black Hills of South Dakota discovered gold. White prospectors flooded the territory. Caring very little about Indian rights, and very much about getting rich, they brought the Sioux situation again to its breaking point. Aware that U.S. citizens were violating treaty provisions, but unwilling to prevent them from searching for gold, federal officials pressured the western Sioux to sign a new treaty that would transfer control of the Black Hills to the United States while General Philip Sheridan quietly moved U.S. troops into the region. Initial clashes between U.S. troops and Sioux warriors resulted in several Sioux victories that, combined with the visions of Sitting Bull, who had dreamed of an even more triumphant victory, attracted Sioux bands who had already signed treaties but now joined to fight.

In late June 1876, a division of the 7th Cavalry Regiment led by Lieutenant Colonel George Armstrong Custer was sent up a trail into the Black Hills as an advance guard for a larger force. Custer’s men approached the village known to the Sioux as Greasy Grass, but marked on Custer’s map as Little Bighorn, and found, given the influx of “treaty” Sioux, as well as aggrieved Cheyenne and other allies, had swelled the population of the village far beyond Custer’s estimation. Custer’s 7th Cavalry was vastly outnumbered and he and 268 of his men were killed.

Custer’s fall shocked the nation. Cries for a swift American response reprisals filled the public sphere and military expeditions were sent out to crush native resistance. The Sioux splintered off into the wilderness and began a campaign of intermittent resistance but, outnumbered and suffering after a long, hungry winter, Crazy Horse led a band of Oglala Sioux to surrender in May of 1877. Other bands gradually followed until finally, in July 1881, Sitting Bull and his followers at last laid down their weapons and came to the reservation. Indigenous powers had been defeated. The Plains, it seemed, had been pacified.
