What Caused the Mexican-American War? Overview, Course, and Results

Causes of the Mexican-American War

The Mexican-American war was a conflict between the United States and Mexico, fought from April 1846 to February 1848. One of the main causes of the war was the annexation of the republic of Texas by the U.S. in 1845. This act was highly controversial and led to tensions between the two countries.

Another cause of the Mexican-American war was a dispute over the border of Texas. Mexico claimed that their border ended at the Nueces River, while the U.S. claimed that it ended at the Rio Grande. This disagreement over territory further escalated the conflict between the two nations.

Course of the Conflict

The Mexican-American war began in April 1846 when U.S. troops crossed the Rio Grande into the disputed territory. This incursion by American forces triggered a series of battles between the two countries, with Mexico ultimately being outmatched by the superior military strength of the United States.

During the course of the war, the U.S. forces captured key Mexican cities such as Monterrey and Mexico City. The conflict came to an end in February 1848 with the signing of the Treaty of Guadalupe Hidalgo, which officially ended the hostilities between the two nations.

Results of the Mexican-American War

As a result of the Mexican-American war, Mexico was forced to cede a significant portion of its territory to the United States. This territory included present-day California, Nevada, Utah, Arizona, New Mexico, and parts of Colorado and Wyoming.

The war also had a lasting impact on the relationship between the United States and Mexico, with tensions remaining high between the two countries for many years to come. The Mexican-American war is a significant event in the history of both nations and continues to shape their political and cultural landscape.
