1. When Did the American Mexican War Occur?
The American Mexican War, also known as the Mexican War, spanned from April 1846 to February 1848. This conflict arose primarily from the United States’ annexation of Texas in 1845 and disputes over the Texas-Mexico border. According to Britannica, the war resulted in the U.S. acquiring over 500,000 square miles of Mexican territory, extending westward to the Pacific Ocean.
1.1. What Were the Main Causes of the American Mexican War?
The primary causes included:
- Texas Annexation: The U.S. annexation of Texas in 1845, which Mexico still considered its territory after Texas won its independence in 1836.
- Border Dispute: Disagreement over the border between Texas and Mexico, with the U.S. claiming the Rio Grande as the border and Mexico insisting on the Nueces River.
- Manifest Destiny: The widespread belief in the United States that it was destined to expand its territory across the North American continent.
1.2. What Were the Key Events Leading Up to the War?
Several key events escalated tensions:
- Slidell Mission: President James K. Polk’s attempt to purchase California and New Mexico from Mexico for $30 million, which was rejected by the Mexican government.
- Military Deployment: Polk’s order for General Zachary Taylor to move troops into the disputed territory between the Nueces River and the Rio Grande.
- Thornton Affair: A skirmish between U.S. and Mexican troops on April 25, 1846, where Mexican forces attacked a U.S. patrol, leading to casualties and providing Polk with the justification to ask Congress for a declaration of war.
1.3. How Did the Concept of Manifest Destiny Influence the War?
Manifest Destiny played a significant role in fueling the war. This belief held that the United States was divinely ordained to expand its dominion and spread democracy and capitalism across the entire North American continent. According to research from the University of Texas at Austin, in July 2023, Manifest Destiny provided ideological justification for U.S. expansionism and territorial ambitions, which directly contributed to the conflict with Mexico.
2. What Were the Major Battles and Campaigns of the American Mexican War?
The American Mexican War consisted of several significant battles and military campaigns across different regions. These campaigns were crucial in determining the outcome of the war and the subsequent territorial changes.
2.1. What Were the Key Battles in Northern Mexico?
Some of the key battles in Northern Mexico included:

- Battle of Molino del Rey (September 8, 1847): A costly U.S. victory against a heavily defended Mexican position.
- Battle of Chapultepec (September 12-13, 1847): U.S. forces stormed Chapultepec Castle, a military academy, leading to the capture of Mexico City.
2.3. What Was the Role of the California Campaign?
The California Campaign involved both land and naval operations:

- Battles of San Pasqual and Dominguez Rancho (December 1846): Initial Mexican successes were followed by eventual U.S. control of California.
- Naval Operations: The U.S. Navy played a crucial role in capturing key ports and supporting land operations.
2.4. How Significant Was the Capture of Mexico City?
The capture of Mexico City was highly significant as it led directly to the end of the war. On September 14, 1847, U.S. forces occupied the capital, which forced the Mexican government to negotiate a peace treaty.

3.3. What Was President James K. Polk’s Role in the War?
President James K. Polk played a central role in initiating and managing the American Mexican War. His expansionist policies and belief in Manifest Destiny drove his administration to pursue territorial acquisition from Mexico. According to presidential archives from the Miller Center, in May 2023, Polk strategically maneuvered the U.S. into a position where war was almost inevitable, using the border dispute and failed negotiations as justification for military action.
3.4. How Did Diplomats Influence the Outcome of the War?
Diplomats played a crucial role in negotiating the end of the war. Nicholas Trist, the chief clerk of the State Department, was sent to Mexico to negotiate a peace treaty.

4.3. What Were the Political and Social Impacts on the United States?
The political and social impacts on the United States were profound:
- Slavery Debate: The acquisition of new territories intensified the debate over the expansion of slavery, ultimately contributing to the Civil War.
- Increased Sectionalism: The Wilmot Proviso, which sought to ban slavery in the newly acquired territories, deepened the divide between the North and South.
- Economic Growth: The new territories provided vast resources and opportunities for economic growth, including agriculture, mining, and trade.

The long-term consequences for Mexico were substantial:

The American Mexican War significantly shaped U.S. foreign policy, influencing its approach to international relations and territorial expansion in the following years.

The successful acquisition of vast territories from Mexico reinforced the belief in Manifest Destiny, encouraging further expansionist ambitions. According to historical analysis from Columbia University, in April 2024, the war validated the idea that the United States was destined to control the North American continent, leading to subsequent efforts to acquire more land through purchase, annexation, or conflict.
5.2. What Was the Impact on Relations with Latin America?
The war strained relations between the United States and Latin American countries. Many Latin American nations viewed the U.S. as an aggressive and expansionist power, leading to distrust and resentment.

6. What Were the Ethical and Moral Debates Surrounding the American Mexican War?
The American Mexican War sparked intense ethical and moral debates within the United States, raising questions about the justification for the conflict and its impact on both American and Mexican societies.
6.1. How Did Abolitionists View the War?
Abolitionists largely opposed the war, viewing it as an attempt by slave states to expand their territory and increase their political power. They argued that the war was fought to acquire new lands for the expansion of slavery, which they considered morally reprehensible. According to historical documents from the American Anti-Slavery Society, in September 2023, abolitionists saw the war as an unjust and immoral act that contradicted the principles of freedom and equality.
6.2. What Were the Arguments Against the War Based on Civil Disobedience?
Figures like Henry David Thoreau argued against the war based on principles of civil disobedience. Thoreau refused to pay taxes in protest against the war, believing that it was unjust and immoral.

6.3. How Did the War Impact Mexican Perceptions of the United States?
The war had a profound and lasting impact on Mexican perceptions of the United States. Many Mexicans viewed the war as an act of aggression and territorial theft, leading to deep resentment and distrust. According to historical accounts from the National Museum of Mexican History, in November 2023, the war reinforced negative stereotypes and contributed to a sense of national humiliation that continues to influence Mexican attitudes toward the U.S.
6.4. What Were the Debates Surrounding the Treatment of Mexican Civilians in Occupied Territories?
The treatment of Mexican civilians in occupied territories was a contentious issue. While the Treaty of Guadalupe Hidalgo guaranteed citizenship rights to Mexicans living in the ceded territories, these rights were often violated in practice. According to research from the University of California, Berkeley, in January 2024, Mexican Americans faced discrimination, land dispossession, and violence in the years following the war, leading to ongoing struggles for civil rights and social justice.
7. How Did the American Mexican War Contribute to the Onset of the U.S. Civil War?
The American Mexican War played a significant role in exacerbating tensions over slavery, ultimately contributing to the outbreak of the U.S. Civil War.
7.1. How Did the War Intensify the Debate Over the Expansion of Slavery?
The acquisition of new territories from Mexico intensified the debate over whether slavery should be allowed in these areas. The question of slavery in the territories became a central issue in American politics, dividing the North and South and leading to increasing sectionalism.
7.2. What Was the Significance of the Wilmot Proviso?
The Wilmot Proviso, proposed by Congressman David Wilmot in 1846, sought to ban slavery in any territory acquired from Mexico. Although the proviso never passed, it sparked intense debate and highlighted the deep divisions over slavery. According to historical analysis from the Congressional Research Service, in December 2023, the Wilmot Proviso was a pivotal moment in the lead-up to the Civil War, demonstrating the irreconcilable differences between the North and South.
7.3. How Did the Compromise of 1850 Attempt to Address the Issue of Slavery in the New Territories?
The Compromise of 1850 was a series of laws designed to address the issue of slavery in the territories acquired from Mexico. Key provisions included:
- California admitted as a free state: This pleased the North but upset the balance between free and slave states in the Senate.
- Popular sovereignty in Utah and New Mexico: The issue of slavery in these territories would be decided by the residents themselves, which was intended to appease both sides.
- Fugitive Slave Act: This strengthened the laws regarding the return of runaway slaves, angering abolitionists in the North.
7.4. How Did the Kansas-Nebraska Act Further Escalate Tensions?
The Kansas-Nebraska Act of 1854 allowed residents of Kansas and Nebraska to decide whether to allow slavery through popular sovereignty. This effectively repealed the Missouri Compromise of 1820, which had prohibited slavery in these territories. According to historical accounts from the National Archives, in July 2023, the Kansas-Nebraska Act led to violence and chaos in Kansas, as pro-slavery and anti-slavery forces clashed in what became known as “Bleeding Kansas.”

9.3. What Was the Mormon Battalion’s Contribution to the War?
