🗽US History Unit 17 – Westward Expansion: America's Frontier (1840-1900)

Key Events and Timeline

• 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

Impact on Native American Populations

• Displacement and forced relocation of Native American tribes from their ancestral lands to make way for American settlers and economic interests
  • Indian Removal Act (1830) and the Trail of Tears (1838-1839) resulted in the forced migration of thousands of Native Americans
• Loss of traditional hunting grounds and resources due to the encroachment of settlers and the development of agriculture and industry
• Decimation of Native American populations through warfare, conflict, and the introduction of European diseases (smallpox, measles)
  • Sand Creek Massacre (1864) and the Battle of Little Bighorn (1876) were notable conflicts between Native Americans and the U.S. military
• Assimilation policies and attempts to eradicate Native American culture through the establishment of Indian boarding schools and the suppression of traditional practices
• Broken treaties and the failure of the U.S. government to honor agreements made with Native American tribes regarding land rights and sovereignty
• Reservation system the confinement of Native American tribes to designated areas, often with limited resources and opportunities
• Long-term effects on Native American communities, including poverty, cultural loss, and intergenerational trauma

Economic Developments

• Gold rushes (California, Colorado, Black Hills) attracted thousands of prospectors and led to the rapid growth of mining towns and regional economies
• Agricultural expansion the development of large-scale farming and ranching operations in the Great Plains and the West, supported by the Homestead Act and advancements in technology
  • Introduction of new crops and livestock (wheat, cattle) adapted to the climate and conditions of the frontier
• Transcontinental Railroad construction created jobs, stimulated commerce, and opened up new markets for goods and resources
• Industrialization the growth of manufacturing and processing industries in the West, such as lumber, meatpacking, and textiles
• Rise of commercial centers and cities (San Francisco, Denver, Seattle) that served as hubs for trade, finance, and transportation
• Expansion of international trade, particularly with Asia and the Pacific, through ports on the West Coast
• Economic disparities and the concentration of wealth in the hands of a few powerful individuals and corporations, such as railroad tycoons and mining magnates

Political Consequences

• Expansion of U.S. territory and the incorporation of new states into the Union (Texas, California, Oregon)
  • Compromise of 1850 a series of measures designed to address the issue of slavery in the newly acquired territories
• Sectional tensions between the North and South over the extension of slavery into western territories, contributing to the outbreak of the Civil War (1861-1865)
  • Kansas-Nebraska Act (1854) and the concept of popular sovereignty heightened tensions and led to violent conflicts (Bleeding Kansas)
• Displacement and disenfranchisement of Native American tribes, as the U.S. government prioritized the interests of settlers and economic development over treaty obligations
• Growth of the federal government's power and influence in the West through the establishment of territories, military presence, and land management policies
• Emergence of new political movements and parties, such as the Populist Party, that advocated for the interests of farmers and workers in the frontier
• Debates over the role of the federal government in regulating and supporting western development, such as the funding of internal improvements (canals, roads)

• Challenges to traditional gender roles and the expansion of opportunities for women in the frontier, such as the right to vote in western territories (Wyoming, 1869)
  • Annie Oakley and Calamity Jane as famous examples of women who defied conventional norms in the West
• Boom and bust cycles of frontier settlements, as communities rapidly grew and declined based on the availability of resources and economic opportunities
• Social stratification and income inequality in frontier societies, with a small elite controlling much of the wealth and power
• Romanticization of the frontier experience in popular culture, literature (dime novels), and later in films and television (Western genre)
