The Treaty of Guadalupe Hidalgo was signed by the United States and Mexico on February 2, 1848, ending the Mexican War and extending the boundaries of the United States by over 525,000 square miles. In addition to establishing the Rio Grande as the border between the two countries, the territory acquired by the U.S. included what will become the states of Texas, California, Nevada, Utah, most of New Mexico and Arizona, and parts of Colorado and Wyoming. In exchange Mexico received fifteen million dollars in compensation for the territory and the U.S. agreed to assume claims from private citizens of these areas against the Mexican government.
