🌽History of Native Americans in the Southwest Unit 9 – US Expansion and Mexican-American War
The US rapidly expanded westward in the early 19th century, driven by Manifest Destiny and population growth. This period saw the annexation of Texas, conflicts with Native American tribes, and technological advancements that facilitated migration.
The Mexican-American War (1846-1848) resulted from tensions over Texas and border disputes. The conflict ended with the Treaty of Guadalupe Hidalgo, ceding vast territories to the US and reshaping North America's political landscape.
Early 19th century marked a period of rapid territorial expansion for the United States
Belief in Manifest Destiny, the idea that US was destined to expand across North America, gained popularity
US population grew rapidly due to high birth rates and increased immigration (Irish, German)
Technological advancements (steamboats, railroads) facilitated westward movement
Removal of Native American tribes from their ancestral lands became a central issue
Indian Removal Act of 1830 authorized the relocation of Native Americans to territories west of the Mississippi River
Trail of Tears, the forced relocation of Cherokee, Muscogee, Seminole, Chickasaw, and Choctaw nations, resulted in thousands of deaths
Annexation of Texas in 1845 and the concept of Manifest Destiny heightened tensions with Mexico
Manifest Destiny
Manifest Destiny, a term coined by journalist John O'Sullivan in 1845, encapsulated the belief that US expansion was inevitable and divinely ordained
Proponents argued that spreading democracy, Christianity, and American values across the continent was a moral obligation
Manifest Destiny provided justification for territorial acquisition through diplomacy, purchase, or force
Idea resonated with many Americans who viewed westward expansion as a means to access new land, resources, and opportunities
Critics argued that Manifest Destiny was a thinly veiled excuse for imperialism and the displacement of Native Americans
Manifest Destiny shaped US foreign policy and led to the annexation of Texas, Oregon Country, and the Mexican Cession
Causes of US Expansion
Population growth and the need for new land and resources drove westward expansion
Economic opportunities, such as gold rushes (California) and agricultural potential, attracted settlers
Technological advancements in transportation and communication made migration easier
Completion of the First Transcontinental Railroad in 1869 greatly facilitated westward movement
Political and ideological factors, including the desire to spread democracy and American values, contributed to expansionist policies
Sectional tensions between North and South over the extension of slavery into new territories
Missouri Compromise of 1820 and the Compromise of 1850 attempted to address this issue
Belief in Manifest Destiny provided a moral and religious justification for territorial acquisition

Impact on Native American Tribes

Native Americans faced displacement, loss of land, and forced assimilation
Many tribes, such as the Navajo and Apache, saw their traditional territories divided by the new US-Mexico border
US government policies aimed at confining Native Americans to reservations and suppressing their cultural practices
Reservation system, which restricted tribes to designated areas, disrupted traditional ways of life
Boarding schools established to assimilate Native American children into white American culture
Increased settlement and resource exploitation led to conflicts between Native Americans and settlers
Gold Rush in California resulted in the displacement and violence against indigenous peoples
Treaties, such as the Treaty of Guadalupe Hidalgo, often failed to protect the rights and interests of Native American tribes
Cultural and Social Consequences
US expansion and the Mexican-American War led to significant cultural and social changes in the Southwest
Influx of American settlers, along with their language, customs, and values, transformed the region
Spanish and Mexican influences, including language, architecture, and cuisine, persisted and blended with American culture
Mestizaje, the mixing of Spanish, indigenous, and African peoples, continued to shape the region's cultural identity
Socioeconomic disparities emerged between the Anglo-American newcomers and the established Mexican and Native American populations
Access to land, resources, and political power often favored the Anglo-American settlers
Anti-Mexican sentiment and discrimination increased in the aftermath of the war
Cultural clashes and tensions between different ethnic and racial groups persisted
Legacy and Modern Perspectives
Mexican-American War and US expansion had lasting impacts on the political, social, and cultural landscape of the Southwest
Acquisition of new territories fueled debates over the extension of slavery, contributing to the growing sectional divide that ultimately led to the American Civil War
Displacement and marginalization of Native American tribes continues to shape contemporary issues and struggles for indigenous rights
Chicano Movement of the 1960s and 1970s sought to reclaim Mexican American identity and challenge discrimination
Ongoing debates over immigration, border security, and cultural identity in the Southwest
Legacy of the war remains contentious, with differing interpretations and perspectives

Others criticize it as an unjust war of aggression and a symbol of American imperialism
Impact of the Mexican-American War and US expansion continues to shape discussions on race, ethnicity, and national identity in the United States
