The Mexican-American War, which lasted from 1846 to 1848, opened up vast territories to American settlers, including present-day California, Arizona, New Mexico, Nevada, Utah, and parts of Colorado and Wyoming. The conflict concluded with the Treaty of Guadalupe Hidalgo, which ceded these lands to the United States, significantly expanding its territory and facilitating westward expansion. This acquisition played a crucial role in shaping the future of the nation and contributed to the concept of Manifest Destiny.
