Settler Pressure: Railroads, Cattle, Gold and the Indigenous Plains
A Cumulative Pressure
By 1850 the Indigenous peoples of the Plains had spent two centuries adapting to a horse-and-buffalo culture. By 1880 that culture had been almost destroyed. The story is not a single catastrophe. It is the story of three settler pressures — the railroad, the cattle industry and gold prospecting — stacking on top of each other, each one renewing the assault on land, food and treaties already weakened by the one before. For the 8-mark Analytical Narrative question, students need to see this as a chain, not a list.
Underneath all three pressures ran a fourth: US government policy, which kept funnelling Plains nations onto smaller and smaller reservations, paid for in unreliable annuities, and policed by Indian agents who often skimmed the food and supplies before they reached the people they were meant to serve.
Three settler pressures combined to destroy Plains Indigenous life: railroads split the buffalo herds and ferried hide hunters; the cattle industry took the grass and water; gold strikes broke treaty lines that were supposed to be permanent. Each renewed the pressure on a shrinking territory.
Railroads as Buffalo-Killers
The First Transcontinental Railroad, completed in 1869, did not just carry passengers; it physically split the great buffalo herd into northern and southern populations that never recombined. After 1870 a new generation of high-velocity rifles and the demand for tanned hides from eastern leather factories turned the bison into a commodity. Rail companies hired contracted hunters to feed crews — William ‘Buffalo Bill’ Cody killed an estimated 4,280 bison in eighteen months supplying the Kansas Pacific.
From the trains themselves, sport shooters fired into the herds for entertainment as carriages rolled past. From around 1872 hide hunters operated in teams across the southern plains, killing the southern herd by 1875. The northern herd followed by 1883. From an estimated 30 million bison in 1800, fewer than 1,000 wild animals remained by 1890. General Philip Sheridan endorsed the slaughter as a deliberate strategy. He is reported to have told the Texas legislature in 1875 to let the hunters kill, skin and sell until the buffalo was gone, because that was the only way to bring lasting peace. Without the bison, Plains nations lost food, clothing, shelter and the centre of their spiritual life.
Cattle on the Open Range
As the bison disappeared, the open range filled with cattle. The same grass that had fed the buffalo now fed the longhorn herds of John Iliff, Charles Goodnight and the eastern-funded ranches that spread across Wyoming, Montana and the Dakotas through the 1870s and early 1880s. Cattle competed for water at the same rivers and creeks the buffalo had used. Ranchers wanted Plains grass cleared of bison entirely, which they regarded as a competitor for forage.
For Indigenous peoples confined to reservations, the result was a double loss. Their hunting territory was now privately stocked with cattle they were not allowed to take, and the federal beef rations promised under treaty — sometimes spoiled, often short — were a poor replacement for the buffalo herds that had once moved through their lands. Hunger pushed nations off reservations to hunt; that hunting brought them into conflict with ranchers and the army; conflict justified further restrictions. The cycle worked against them at every step.
Weaker answers refer to ‘the Sioux’ as if all Plains nations were one. They were not. The Lakota Sioux, Cheyenne, Arapaho, Comanche, Crow and Pawnee had distinct languages, leaderships and very different relationships with the US Government. The Crow scouted FOR Custer at Little Bighorn against their Lakota rivals; the Pawnee fought as US Army auxiliaries on the central Plains. The specification deliberately uses ‘Indigenous peoples’ to underline this diversity. In a Q3 importance answer, naming a specific nation (the Lakota, the Cheyenne) signals up-to-date subject literacy and unlocks higher bands.
Gold Strikes That Broke Treaty Lines
No settler pressure broke treaty lines as quickly as gold. In the summer of 1858 prospectors found gold near Pike’s Peak in present-day Colorado — on land guaranteed to the Cheyenne and Arapaho under the 1851 first Fort Laramie Treaty. Within a year, around 100,000 prospectors had crossed those hunting grounds; the slogan ‘Pike’s Peak or Bust’ rolled across the Mississippi. The federal government answered not by enforcing the treaty but by writing a new one in 1861 that took back most of the territory it had previously guaranteed.
The pattern repeated. In 1863 the prospector John Bozeman blazed a trail north from the Oregon Trail to the new Montana goldfields, cutting straight through the Lakota Powder River country. Red Cloud’s War (1866–68) was fought to close it. In 1874 a US Army expedition under George Armstrong Custer confirmed gold in the Black Hills of Dakota — territory recognised as Lakota under the 1868 second Fort Laramie Treaty just six years earlier. Within months around 15,000 prospectors had poured in. The treaty collapsed; the Battle of the Little Bighorn (1876) followed; and the cycle covered in Lessons 11 and 12 began.
Students regularly mix up the two Fort Laramie Treaties — an error that keeps Q3 answers in the lower bands. The 1851 first treaty was a multi-nation council, organised by the US Indian agent Thomas Fitzpatrick, that recognised hunting territory and promised annuities in return for safe passage on the Oregon Trail. The 1868 second treaty ended Red Cloud’s War, closed the Bozeman Trail, and granted the Black Hills to the Lakota. Different decades, different leaders, different outcomes. A useful memory hook: 1851 was about access (a peace council), 1868 was about ownership (a Lakota victory). Every gold-strike sentence in this lesson runs against ONE of those treaties — never both at once.
US Policy: Reservations, Annuities and Indian Agents
Underneath the railroad, cattle and gold pressures, the US policy of annuity payments and concentration onto reservations was failing on its own terms. Reservations shrank with each treaty revision. Annuities arrived late, short, or spoiled. The Indian agents who managed the rations and supplies were political appointees, often unsupervised, frequently corrupt — the agent Andrew Myrick’s 1862 remark that hungry Santee Sioux farmers should “eat grass” helped trigger Little Crow’s War in Minnesota that summer.
By the late 1870s, dependence on government rations — with the buffalo gone, the open range fenced and the Black Hills overrun — was the daily reality of Plains life. Concentration was failing because each new wave of settler pressure renewed the squeeze on the same shrinking territory. For the 8-mark narrative account, chain the four pressures together rather than listing them.
Three gold strikes broke three treaty lines: Pike’s Peak (1858–59) overran Cheyenne and Arapaho hunting grounds promised in the 1851 first Fort Laramie Treaty; the Bozeman Trail goldfields (1862–63) cut Lakota Powder River country; and the 1874 Black Hills strike broke the 1868 second Fort Laramie Treaty — triggering Little Bighorn in 1876.
