What were the causes and effects of the Mexican-American War?
The Mexican-American War, fought between 1846 and 1848, was a significant conflict between the United States and Mexico that had far-reaching consequences for both countries. In this article, we will explore the causes of the war, its battles and outcomes, and the effects of the war on both Mexico and the United States.
Causes of the Mexican-American War
The Mexican-American War had multiple causes, including:
• The annexation of Texas: In 1836, Texas declared its independence from Mexico and became the Republic of Texas. The United States government later annexed Texas in 1845, sparking tension with Mexico, which had long considered Texas a province.
• The boundary dispute: The Treaty of Adams-Onís in 1819 established the border between the United States and Mexico, but there was controversy over the border between New Mexico and Texas.
• American expansionism: The United States was undergoing a period of westward expansion, with many citizens believing that it was the country’s manifest destiny to expand its territory from sea to sea.
• The Mexican economy: Mexico was facing economic difficulties, including a severe economic depression and a debt crisis. This led to the forced sale of large tracts of land to American interests, further straining relations with the United States.
Battles and Outcomes of the Mexican-American War
The war was fought on several fronts, with the following key battles taking place:
• Battles of Palo Alto, Resaca de la Palma, and Monterrey: The first three battles of the war, fought in May 1846, were a series of skirmishes between American forces and the Mexican army near the Rio Grande River. The battles were bloody, but the Mexican army retreated, giving the United States control of the territory.
• The Siege of Mexico City: After taking control of Mexico City on September 14, 1847, American forces occupied the city until they were forced to evacuate it in September 1848.
• Treaty of Guadalupe Hidalgo: The war ended with the signing of the Treaty of Guadalupe Hidalgo on February 2, 1848. The treaty marked a significant turning point in the history of both countries.
Effects of the Mexican-American War
The effects of the Mexican-American War were far-reaching and profound for both Mexico and the United States.
Effects on Mexico
• Loss of territory: The treaty ceded approximately 529,000 square miles of land to the United States, including present-day California, Nevada, Utah, Arizona, New Mexico, Texas, and parts of Colorado, Kansas, Oklahoma, and Wyoming.
• Financial losses: The war led to a severe economic crisis in Mexico, with the country’s foreign debt increasing and its currency declining in value.
• Social and political unrest: The war led to significant social and political unrest in Mexico, including a surge in violence and civil strife.
Effects on the United States
• Expansion of territory: The war led to a significant expansion of American territory, with the United States acquiring a vast amount of new land.
• End of the manifest destiny: The war marked the end of the concept of manifest destiny, as the country’s expansionist ideology gave way to a more practical and diplomatic approach to acquiring new territory.
• Increased power and influence: The war marked a significant increase in American power and influence, with the United States emerging as a dominant force in the Western Hemisphere.

The Mexican-American War was a significant conflict that had profound effects on both Mexico and the United States. The war was sparked by a combination of factors, including the annexation of Texas, the boundary dispute, American expansionism, and Mexico’s economic difficulties.
