The Treaty of Guadalupe Hidalgo

The Treaty of Guadalupe Hidalgo, signed in 1848, ended the Mexican-American War and established a new border between the United States and Mexico. This treaty resulted in the U. S. acquiring over 500,000 square miles of territory, including present-day California, Nevada, Utah, Arizona, and parts of Colorado and New Mexico. The treaty was significant not only for expanding U. S.

territory but also for creating new challenges regarding the status of individuals living in the newly acquired lands, including questions about citizenship and rights.
