US Expansionism and Manifest Destiny in the 19th Century

Overview of US Imperial Expansion in the 19th Century

Focus on the themes of expansionism and imperialism in relation to the US and its impacts on Latinx and Chicanx studies.

Key historical events and concepts:

• Manifest Destiny

• The U.S.-Mexico War (La Guerra)

• Forced migrations and the effects of conquest.

Manifest Destiny

Definition: The belief that it was the divinely ordained right of the United States to expand its territory across the continent, often viewed as an imperative justified by both economic and religious factors. This ideology inspired a sense of entitlement among Anglo Americans, framing the expansion as a way to spread democracy and civilization.

• Used to justify the displacement of indigenous peoples, leading to widespread and systematic removal from ancestral lands. The rhetoric of Manifest Destiny framed indigenous peoples as obstacles to progress.

• Views of Land Use: Many Anglo Americans regarded uncultivated land as wasted, believing it should be cultivated for agriculture and settlement. This perspective stemmed from a Eurocentric view of land ownership as private property, contrasting sharply with the communal relationships that many Native American tribes held with their ancestral lands.

• Ideological Underpinning: Manifest Destiny instilled a sense of duty among Anglo Americans, convincing them that they were not merely expanding territory, but were civilizing the continent through their expansionist efforts.

Consequences of Manifest Destiny

• Clashing Worldviews Regarding Land Ownership and Usage:

  • Anglo Americans saw themselves as entitled to claim vast tracts of land, while indigenous peoples had a deeply rooted sense of connection and stewardship towards the land.

  • This ideological conflict led to violent confrontations and acts of brutality against Native peoples, often labeled as justifiable in the name of progress and civilization.

Historical Context of U.S.-Mexico Relations

• Pre-war tensions stemmed from growing U.S. expansionist ambitions and the contentious annexation of Texas in 1845, driven by the belief that it was America’s destiny to occupy the land.

• Mexican View: Contrary to U.S. belief, Mexico regarded Texas as an integral part of its nation, leading to tensions as American settlers moved into the region under the auspices of Manifest Destiny.

• Troops were positioned in contested territories, particularly along the Rio Grande, leading to skirmishes that escalated into the declaration of war.

The U.S.-Mexico War (1846-1848)

• Timeline: 1846: Formal declaration of war; 1848: Treaty of Guadalupe Hidalgo signed, formally ending the conflict.

• Key Events:

  • U.S. troops, led by General Zachary Taylor and later General Winfield Scott, moved strategically into Mexico, capturing key cities including Veracruz and Mexico City, showcasing military superiority.

  • The war completed American territorial expansion from coast to coast, significantly altering the geopolitical landscape of North America.

• The Treaty of Guadalupe Hidalgo: Resulted in the cession of approximately 55% of Mexico’s territory to the U.S., including present-day California, Nevada, Utah, Arizona, and portions of Colorado and New Mexico.

Impacts on Indigenous Peoples and Legacy

• The war and subsequent treaty led to the establishment of the U.S.-Mexico border, fundamentally altering the lives of many inhabitants who suddenly became foreigners in their own land, complicating issues of citizenship and land rights.

• Cultural Implications: The memory of the land loss influenced Mexican American identity formation and activism, playing a critical role in the Chicano civil rights movement and asserting claims to land and cultural heritage in the 20th century.

• The repercussions of territorial expansion also fueled tensions leading to the Civil War, particularly regarding the political power structure and the contentious issue of slavery in newly acquired territories.

Ninos Heroes

• Event: Youth cadets defending Chapultepec Castle against U.S. forces during the war, often celebrated in Mexican culture as an emblem of bravery and resistance.

• Significance: Recognized in Mexico on September 13 as a national holiday, the actions of these youthful defenders symbolize the fight against foreign invasion and the defense of national sovereignty.

The Treaty of Guadalupe Hidalgo

• Resulted in a considerable territorial loss for Mexico, establishing a new border shaped largely by access to resources and geopolitical interests.

• Defined territories that now encompass much of the U.S. Southwest; the socio-political ramifications are still felt today.

• Set the stage for ongoing socio-political dynamics between the U.S. and Mexico, influencing immigration patterns, bilateral relations, and cross-border cultural exchanges.

Consequences of the War

• Formation of a new U.S. territorial identity as an imperial power capable of military conquest and territorial negotiation.

• Continued expansionist policies initiated during this period laid the groundwork for future invasions and colonization in Latin America, fostering an attitude of interventionism in U.S. foreign policy.

• Development of socio-economic structures supported by U.S. interests in resource extraction from Central America and the Caribbean, establishing long-term economic dependencies and exploitative practices.

Key Themes for Future Study

• Examining the effects of U.S. territorial expansion on young Latin American republics in the 19th century, including the rise of nationalism and the struggle for sovereignty.

• The concept of being "foreigners in their native lands" among Chicanos and how this idea has influenced cultural and political movements throughout the 20th century.

• Continued relevance of Manifest Destiny in modern U.S. foreign policy discussions, as it reflects underlying ideologies that shape American interventionist tendencies in international relations today.
