Obj 1–2: Great Plains & Manifest Destiny
The Great Plains were the last settled area because early explorers like Major Stephen Long called it a "Great American Desert" — hostile climate, few trees, and perceived as unfit for farming. By the 1840s, economic opportunity and ideology shifted American thinking.
Manifest Destiny was coined by magazine editor John O'Sullivan in 1845 — the belief that Americans were divinely ordained to expand democratic institutions across the continent, exposing Native peoples to Protestant values and "civilizing" development. The federal government used it to justify westward expansion, especially during the Civil War.

Obj 3a: Farming — Homestead Act
Congress passed the Homestead Act (1862) — any head of household or individual over 21 (including women and African Americans) could claim 160 acres of public land, live on it for 5 years, and own it. The Pacific Railway Act (1862) was passed the same year, enabling a transcontinental railroad.
Challenges: Harsh weather, droughts, insects (grasshopper plagues), isolation, and debt. Eastern farming techniques did not work on the dry plains.
Innovations: Steel plow (broke tough sod), windmill (water access), dry farming techniques, and barbed wire (cheap fencing without trees).

Obj 3b: Mining — Gold & Silver
Major strikes: Comstock Lode (Nevada, 1859) — massive silver deposit; Pike's Peak, Colorado (1859) — gold rush. Mining towns were rough boomtowns that grew explosively and often collapsed just as fast. Life was dangerous, transient, and male-dominated. "Wildcatting" — risky exploratory drilling — was the norm.

Obj 3c: Ranching — Cowboys & Railroads
The cattle industry exploded after the Civil War. Cowboys drove herds north on the Chisholm Trail to railroad towns (Abilene, Dodge City). The railroad was essential — it connected ranchers to eastern markets. The myth: romantic, free, heroic cowboy. The reality: dangerous, low-paid, often minority (many cowboys were Black or Hispanic), seasonal labor with grueling long drives.

Obj 4: Plains Indians & the Dawes Act
Plains Indians (Sioux, Cheyenne, Comanche) were nomadic, centered on buffalo hunting. The U.S. government systematically destroyed the buffalo herds to undermine Native life. Conflicts included the Sand Creek Massacre (1864), the Battle of Little Bighorn (1876) — Custer's Last Stand, where Sioux and Cheyenne defeated the 7th Cavalry — and the Wounded Knee Massacre (1890).
The Dawes Severalty Act (1887): broke up tribal communal lands into individual 160-acre plots to force assimilation. "Surplus" land sold to white settlers. Devastated tribal culture and self-governance. Native Americans not granted formal citizenship until 1924.
