Mexican American War

The Mexican-American War (1846-1848) was a conflict between the United States and Mexico, primarily over territorial disputes after the U.S. annexed Texas. Tensions rose due to differing claims on land and the desire of the U.S. to expand westward, an idea known as Manifest Destiny. The war resulted in significant U.S. victories, leading to the Treaty of Guadalupe Hidalgo, in which Mexico ceded large territories, including present-day California, Arizona, and New Mexico, to the U.S. This war intensified debates over slavery and contributed to tensions that ultimately led to the American Civil War.
