How did the Treaty of Guadalupe Hidalgo affect Mexico?

The Treaty of Guadalupe Hidalgo, signed in 1848, significantly impacted Mexico by ceding approximately half of its territory to the United States, including present-day California, Arizona, New Mexico, Nevada, Utah, and parts of Colorado and Wyoming. This loss of land diminished Mexico's economic resources and territorial claims, leading to a period of instability and conflict within the country. Additionally, the treaty exacerbated national identity issues and fueled resentment toward the United States, influencing Mexico's political landscape for years to come.
