Primary Sources: Wars & Conflicts

The Mexican-American War fought from 1846 to 1848, stemmed from tensions over the annexation of Texas and territorial disputes along the U.S.-Mexico border. American expansionist fervor and Manifest Destiny fueled the conflict, leading to significant battles such as the Siege of Fort Texas and the Battle of Buena Vista. The war concluded with the signing of the Treaty of Guadalupe Hidalgo, in which Mexico ceded vast territories, including California, New Mexico, and Texas, to the United States in exchange for $15 million. The war's outcome reshaped the map of North America and exacerbated tensions over slavery in the United States.
