Treaty of Guadalupe Hidalgo Signed: Mexico Loses Half Its Territory
Mexico and the United States sign the Treaty of Guadalupe Hidalgo to end the Mexican-American War, compelling Mexico to cede over half its territory including present-day California, Nevada, Utah, and parts of Arizona, New Mexico, Colorado, and Wyoming. This massive land transfer solidified U.S. dominance across the continent while leaving a deep demographic and cultural imprint on the Southwest that persists today.
