The Mexican Cession became part of the United States as a result of the Treaty of Guadalupe Hidalgo, signed in 1848, which ended the Mexican-American War. Following the U.S. victory in the war, Mexico ceded a vast territory that included present-day California, Nevada, Utah, Arizona, and parts of Colorado and New Mexico. In exchange, the U.S. paid Mexico $15 million and assumed certain claims of American citizens against the Mexican government. This territorial acquisition significantly expanded U.S. territory and intensified debates over slavery in the newly acquired lands.
