The Mexican-American War was a conflict that occurred between the United States and Mexico from 1846 to 1848.
The issue of Texas, which had previously declared its independence from Mexico in 1836 and was subsequently acquired by the United States in 1845, was the primary reason that the war was waged.
Mexico did not acknowledge Texas as being a part of the United States and considered the annexation of Texas to be an act of aggression against Mexico.
During the course of the conflict, there were a number of notable engagements that took place, including:
- The Battle of Palo Alto
- The Battle of Buena Vista
- The Battle of Chapultepec.
The United States of America emerged triumphant and coerced Mexico into signing the Treaty of Guadalupe Hidalgo. This treaty gave the United States control over a significant portion of Mexico’s territory.
The war was met with strong opposition in both the United States of America and Mexico, and it had a considerable effect on the political and social landscape of both nations.
