The Mexican-American War began on April 25, 1846, and ended on February 2, 1848, with the signing of the Treaty of Guadalupe Hidalgo. This conflict arose from territorial disputes following the annexation of Texas by the United States. The war resulted in significant territorial gains for the U.S., including present-day California, Arizona, New Mexico, and parts of Colorado, Utah, and Nevada.
