History Of The Cheyenne Tribe

Researching Plains Tribal History Is Messier Than You Think

I spent three weeks last year trying to track down reliable primary source material on Cheyenne military society structure before the reservation era. Most people writing about this just repeat the same five or six secondary sources without actually checking where those claims originated. The Cheyenne, like most Plains nations, had an oral tradition that European-American historians initially treated as myth rather than documented history. That bias still shows up in textbooks today. The History Of The Cheyenne Tribe covers thousands of years, but the well-documented period really begins around the 1600s when they migrated from the Upper Mississippi woodlands into the Great Plains. Before acquiring horses, they were a semi-sedentary people who farmed maize and lived in earth lodges. The horse transformed everything. By the early 1700s, they were fully nomadic bison hunters, and that cultural shift rearranged their entire social and political structure. Here is the part most simplified accounts skip: the Cheyenne did not arrive on the Plains as a single unified tribe. They were a confederacy that absorbed smaller groups, including remnants of the Hodenosaunee (Huron) who had been displaced from the east. The Dog Soldiers, often portrayed as a singular militant faction in popular media, were actually one military society among several, and their political influence waxed and waned depending on the era and the specific conflict.

I ran into a real problem when trying to verify the timeline of the Cheyenne division into Southern and Northern bands. The split is commonly dated to the 1820s or 1830s, but the sources disagree, and the splitting was not a formal event. It was a gradual migration pattern driven by internal debate over how to respond to encroaching settlers and U.S. military pressure. The Southern Cheyenne moved south into Kansas and Colorado territory, while the Northern Cheyenne stayed closer to the Yellowstone River. Some bands simply chose different leaders and different strategies. I ended up cross-referencing three separate ethnographic records from the 1880s and comparing them against treaty documents from the National Archives. The dates never quite line up, and that is normal for this kind of research. The Cheyenne sacred artifacts, particularly the Sweet Grass Bundle and the Arrow Fetish, are central to understanding their spiritual and political life. These were not decorative objects. They functioned as constitutional documents in a practical sense. The bundle could be carried into council to legitimize decisions, and certain articles of the treaty negotiations in the 1850s and 1860s were framed as commitments made under the authority of these sacred items. Treaties written by Indian agents often failed to capture this dimension, which is why the Cheyenne frequently disagreed with the U.S. government about whether agreements had been honored. The government was looking for signatures on paper. The Cheyenne were looking at whether ceremonial obligations had been fulfilled. Sand Creek in 1864 is one of the most poorly understood events in American western history. Colonel John Chivington attacked a camp of Cheyenne and Arapaho who believed they were under U.S. protection. The chief Peace John had raised both the American flag and a white flag. Chivington ordered the attack anyway, killing an estimated 150 to 200 people, mostly women and children. The survivors described the scene in subsequent investigations, and a joint congressional committee was formed. Chivington was never prosecuted. This event, rather than any Cheyenne aggression, triggered the escalating cycle of violence that followed across the Southern Plains.

The War of 1865 to 1869, sometimes called the Southern Cheyenne War, saw coordinated action between the Cheyenne, Arapaho, and Lakota. The Battle of the Washita in 1868, where Custer attacked Black Kettle's village, is usually presented as a military victory. Black Kettle had signed the 1867 Treaty of Fort Laramie and was trying to maintain peace. Custer killed roughly 100 people, most of them non-combatants. The Cheyenne response was not irrational. They had been trying diplomacy for years and were being attacked regardless. One thing I always check when reading about this period is whether the author distinguishes between the Dog Soldiers and the broader Cheyenne leadership. The Dog Soldiers were a military society that gained increasing political power from the 1850s onward, particularly among the Southern Cheyenne. They were not the entire tribe making decisions. The older civil chiefs, the So’aa'e or "People," still held significant authority, especially in matters of peace and religion. Conflict between these two governance streams is a recurring theme, and many historical accounts collapse them into a single monolithic group. That is inaccurate and it changes how you interpret their actions. The reservation period began in earnest after the 1868 Treaty of Fort Laramie established the Cheyenne and Arapaho reservation in southern Nebraska. When gold was discovered in the Pike's Peak region and pressure mounted to open that land, the U.S. government negotiated the 1876 Treaty, also known as the Treaty of Little Bighorn, which ceded the Sand Creek area and opened the reservation to settlement. This is where the land loss accelerated rapidly. By the 1880s, the Southern Cheyenne and Southern Arapaho were confined to what is now south-central Oklahoma. The Northern Cheyenne, led by Dull Knife and Little Wolf, resisted removal and attempted a famous escape back to Montana in 1879. About 94 people made it back to the Northern Cheyenne reservation near the Big Horn Basin in Wyoming, where they remain today.

Language is another area where general sources get things wrong. Cheyenne, or Tsėhésenėstsestȯtse, is an Algonquian language. It is not related to Lakota or Hidatsa, which are often grouped together in discussions of Plains cultures. The linguistic distance matters because it shapes how oral histories are structured and preserved. Cheyenne has a complex verb system that encodes evidentiality, meaning the grammar itself signals whether the speaker directly witnessed an event or is relaying information. This affects how historians should read translated accounts. A narrative might describe something the speaker was not personally present for, and that nuance gets lost in English translation. I encountered this directly when reading a 19th-century missionary transcript of a Cheyenne elder's account of the Sand Creek aftermath. The English version read like a firsthand witness report, but the original Cheyenne verb forms indicated the speaker was recounting what others had told them. That is a subtle grammatical distinction that completely changes how you weight the source. I flagged it in my notes and adjusted my interpretation accordingly. This is the kind of thing you miss if you are reading only secondary translations without checking the linguistic markers. The Peacemaker religion, also known as the Sweetgrass Church, emerged in the late 19th century as a response to cultural disruption. It combines traditional Cheyenne spirituality with elements of Christianity and emphasizes healing, sobriety, and community restoration. It remains active today and is one of the continuous religious traditions that survived the boarding school era and the suppression of Native ceremonies. Understanding this movement is important because it shows how Cheyenne governance and identity adapted rather than simply disappeared.

Current population estimates place the combined Cheyenne and Arapaho enrollment at roughly 16,000 to 18,000, with the majority living in Oklahoma and a smaller but politically significant population in Montana. The Cheyenne River Sioux and other neighboring tribes share some cultural overlap but are distinct nations with their own histories and sovereignty. I have seen too many casual references that conflate Plains tribes into a single category. They are not interchangeable. Each has its own political structure, treaty relationships, and legal standing. For anyone doing serious research, the best starting point is the collection of Cheyenne oral narratives recorded by John G. Neihardt and later scholars at the State Historical Society of North Dakota, along with the archived interviews from the WPA Federal Writers' Project that include firsthand accounts from Cheyenne elders born in the mid-1800s. The National Anthropological Archives also holds correspondence from early ethnographers like James Mooney, though you have to read those documents critically because their framing reflects the biases of their time. Cross-referencing with Cheyenne-authored and Cheyenne-edited works, including writings by Richard Erdoes and later scholars like David Treuer, gives you a much more complete picture than relying on old government reports alone. The main limitation across all of this is that pre-contact Cheyenne history is reconstructed from linguistics, archaeology, and later oral tradition. There is no written record from before European contact. Archaeological evidence places them in the Minnesota-Wisconsin area before the westward migration, but the exact timing and route are still debated among historians. This uncertainty is real and it should be stated plainly rather than smoothed over with confident language that sounds better in a textbook.
