US HISTORY

• Boomtowns (Comstock Lode/Strike)

Boomtowns were rapidly growing towns that sprang up near mining sites.

The Comstock Lode (1859) was a massive silver strike in Nevada.

It attracted thousands of prospectors and led to the creation of Virginia City.

Boomtowns often turned into ghost towns once resources were depleted.

• Miners (what were they called...)

Often referred to as “Forty-Niners” during the 1849 California Gold Rush, and prospectors or placer miners in general.

They searched for gold, silver, and other valuable minerals.

Life was harsh and dangerous—long hours, cave-ins, and exposure to toxic materials.

Many were immigrants from places like China, Mexico, and Europe.

• Open Range Grassland

Vast areas of unfenced public land in the West, used for cattle grazing.

Cowboys and ranchers would let cattle roam freely.

Ended in the late 1800s due to overgrazing, barbed wire fences, and harsh winters.

Essential to the cattle industry and cowboy culture.

• Homestead Act (1862)

Gave 160 acres of free land to any U.S. citizen willing to farm it for 5 years.

Encouraged westward migration and settlement of the Great Plains.

Many settlers struggled due to harsh conditions, lack of resources, and isolation.

Benefited some, but also displaced Native American tribes.

• Dawes Act (1887)

Aimed to assimilate Native Americans by breaking up tribal lands.

Gave individual Native families 160-acre plots; surplus land was sold to settlers.

Undermined tribal culture and led to loss of Native American land.

Was part of a broader U.S. policy of forced assimilation.

• Sand Creek Massacre (1864)

A brutal attack by U.S. troops on a peaceful Cheyenne and Arapaho village in Colorado.

Led by Colonel John Chivington; hundreds of Native men, women, and children were killed.

Sparked outrage and intensified conflict between Native tribes and the U.S. government.

• Impact of Westward Expansion

Displacement and suffering of Native American tribes.

Rapid industrial and agricultural growth.

Environmental changes from farming, mining, and railroads.

Creation of new states and infrastructure.

Led to conflict (Indian Wars), cultural changes, and reshaping of American identity.
