1. What Were the Main Causes of the Mexican-American War?
The main causes of the Mexican-American War were the annexation of Texas by the United States in 1845 and a border dispute. The war resulted from the US annexation of Texas and a dispute over whether Texas ended at the Nueces River (as Mexico claimed) or the Rio Grande (as the U.S. claimed).
1.1 Texas Annexation
The annexation of Texas by the United States in 1845 significantly heightened tensions with Mexico. Mexico had never formally recognized Texas’ independence after the Texas Revolution in 1836 and viewed the annexation as an act of aggression. This move by the U.S. was seen as a direct challenge to Mexico’s territorial integrity.
1.2 Border Dispute
The dispute over the Texas-Mexico border further fueled the conflict. The United States claimed the border was the Rio Grande, while Mexico insisted it was the Nueces River, further north. This disagreement led to conflicting claims over a substantial territory, setting the stage for military confrontation.
1.3 Manifest Destiny
Manifest Destiny, the belief that the United States was destined to expand across the North American continent, played a crucial role in the lead-up to the war. This ideology drove American expansionist ambitions and justified the acquisition of new territories, including those claimed by Mexico.
1.4 Failed Negotiations
Diplomatic efforts to resolve these disputes failed. The United States sent John Slidell to Mexico to negotiate the purchase of California and New Mexico and to settle the border issue. However, the Mexican government refused to meet with Slidell, leading to further deterioration of relations and paving the way for war.
2. What Were the Key Battles and Military Campaigns?
The key battles and military campaigns of the Mexican-American War included significant victories for the United States, shaping the war’s outcome and territorial changes. Zachary Taylor’s campaigns, the capture of Mexico City, and the battles in California were particularly decisive.
2.1 Zachary Taylor’s Campaigns
Zachary Taylor, a prominent U.S. general, led successful campaigns in northern Mexico. His victories at Palo Alto and Resaca de la Palma in May 1846 secured American control over the disputed territory north of the Rio Grande. These early wins were crucial in establishing American dominance in the region.
2.2 Battle of Buena Vista
In February 1847, Taylor faced a much larger Mexican army at Buena Vista. Despite being outnumbered, his forces achieved a decisive victory. This battle solidified Taylor’s reputation and further weakened Mexican resistance in the north.
2.3 Winfield Scott’s Veracruz Campaign
Winfield Scott launched an amphibious invasion of Veracruz in March 1847. The city quickly fell to American forces after a siege. This campaign opened a direct route to Mexico City and shifted the war’s focus to the heart of Mexico.
2.4 Capture of Mexico City
Scott’s campaign culminated in the capture of Mexico City in September 1847. Key battles at Cerro Gordo, Contreras, Churubusco, and Chapultepec led to the city’s fall. This victory effectively ended the war, forcing Mexico to negotiate a peace settlement.
2.5 California Campaign
Meanwhile, in California, American forces, including the U.S. Navy and local militias, gained control over the territory. Key events included the Bear Flag Revolt and battles at San Pasqual and Los Angeles. By early 1847, California was firmly under U.S. control.

Under the treaty, Mexico ceded a vast territory to the United States, including present-day California, Nevada, Utah, most of Arizona, and parts of New Mexico, Colorado, and Wyoming. This area totaled over 500,000 square miles, significantly expanding the U.S.

The treaty included provisions to protect the rights of Mexican citizens living in the ceded territories. They were given the option to become U.S. citizens or retain their Mexican citizenship. The treaty aimed to safeguard their property rights and cultural heritage.
3.4 Border Establishment
The treaty officially established the Rio Grande as the border between Texas and Mexico. This resolved the long-standing border dispute that had been a major cause of the war.
3.5 Legacy of the Treaty
The Treaty of Guadalupe Hidalgo had a lasting impact on both the United States and Mexico. For the U.S., it fulfilled Manifest Destiny and facilitated westward expansion. For Mexico, it represented a significant loss of territory and had long-term economic and political consequences.
4. What Were the Territorial Results of the War?

Mexico lost nearly half of its territory, a devastating blow to its national pride and economy. The loss of these lands had long-term consequences, contributing to political instability and economic hardship.

The slavery debate led to the formation of new political parties, such as the Free Soil Party, which opposed the expansion of slavery. These parties played a crucial role in reshaping the political landscape and setting the stage for the Civil War.
7.4 Compromise of 1850
The Compromise of 1850 was an attempt to resolve the issue of slavery in the newly acquired territories. It included measures such as the admission of California as a free state and the passage of the Fugitive Slave Act. However, these measures only provided a temporary respite.
