Which treaty was signed at the end of the Mexican war?

The treaty signed at the end of the Mexican-American War was the Treaty of Guadalupe Hidalgo, which was ratified in 1848. This treaty resulted in the United States acquiring a significant portion of Mexico's northern territory, including present-day California, Arizona, New Mexico, Nevada, Utah, and parts of Colorado and Wyoming. In exchange, the U.S. paid Mexico $15 million and assumed certain claims of American citizens against Mexico. The treaty significantly expanded U.S. territory and set the stage for further westward expansion.
