What was a major outcome of the Treaty of Guadalupe Hidalgo?

The Treaty of Guadalupe Hidalgo, signed in 1848, was significant because it formally ended the Mexican-American War, which had been fought between the United States and Mexico from 1846 to 1848. One of the most important outcomes of the treaty was the territorial changes it brought about; it resulted in the United States acquiring a vast amount of land from Mexico, including present-day California, Nevada, Utah, Arizona, and parts of Colorado and New Mexico. This territorial expansion was crucial in shaping the future of the United States, contributing to its growth as a nation and intensifying debates over slavery in the newly acquired territories. The treaty not only marked the conclusion of hostilities but also set the stage for significant changes in U.S.-Mexico relations and the demographic landscape of the region.
