🗽US History Unit 17 – Westward Expansion: America's Frontier (1840-1900)
Westward Expansion reshaped America from 1840 to 1900. Driven by Manifest Destiny, settlers pushed west, seeking land and opportunity. This era saw the California Gold Rush, Homestead Act, and completion of the Transcontinental Railroad.
The frontier's closing in 1890 marked the end of an era. While expansion brought economic growth, it also led to Native American displacement and environmental changes. The period's legacy continues to influence American identity and culture today.
Louisiana Purchase (1803) doubled the size of the United States and opened up vast new territories for exploration and settlement
Lewis and Clark Expedition (1804-1806) explored and mapped the newly acquired Louisiana Territory, paving the way for future westward expansion
Indian Removal Act (1830) authorized the forced relocation of Native American tribes from their ancestral lands in the southeastern United States to territories west of the Mississippi River
Trail of Tears (1838-1839) resulted in the forced migration of approximately 60,000 Native Americans, leading to widespread suffering and loss of life
California Gold Rush (1848-1855) attracted hundreds of thousands of prospectors and settlers to the West Coast, rapidly increasing the population and economic development of the region
Homestead Act (1862) provided 160 acres of public land to settlers who lived on and improved the land for five years, encouraging westward migration and agricultural development
Completion of the First Transcontinental Railroad (1869) connected the East and West Coasts, facilitating faster and more efficient transportation of goods and people
Closing of the Frontier (1890) marked the end of the era of westward expansion, as the U.S. Census Bureau declared that there was no longer a clear line of advancing settlement
Motivations for Westward Expansion
Manifest Destiny the belief that it was the divine right and duty of the United States to expand across the North American continent
Economic opportunities such as gold rushes, mining, and agricultural prospects attracted settlers and entrepreneurs to the West
Desire for land ownership and self-sufficiency motivated many Americans to seek out new territories and establish homesteads
Population growth and immigration in the eastern United States created a need for new land and resources
Government policies and incentives, such as the Homestead Act and land grants, encouraged westward migration
Advancements in transportation, including the development of railroads and the Oregon Trail, made travel to the West more accessible
Escape from societal constraints and the allure of adventure and a fresh start appealed to many seeking a new life in the frontier
Major Trails and Routes
Oregon Trail a 2,000-mile overland route that connected the Missouri River to the Pacific Northwest, used by hundreds of thousands of settlers, farmers, and entrepreneurs
Began in Independence, Missouri, and ended in Oregon City, Oregon
Hazards along the trail included river crossings, disease (cholera), and conflicts with Native Americans
Santa Fe Trail a 900-mile commercial highway connecting Missouri to Santa Fe, New Mexico, used primarily for trade with Mexico
California Trail a 3,000-mile route that branched off the Oregon Trail, leading to the goldfields and settlements of California
Mormon Trail a 1,300-mile path from Illinois to Utah, used by members of the Church of Jesus Christ of Latter-day Saints (Mormons) seeking religious freedom and a new home
Overland Stage Routes a network of stagecoach lines that transported passengers, mail, and goods across the frontier, connecting settlements and outposts
Pony Express (1860-1861) a short-lived but iconic mail service that used horseback riders to deliver messages between Missouri and California
Transcontinental Railroad a network of railroads that connected the East and West Coasts, completed in 1869, revolutionizing transportation and commerce in the United States
