In February of 1848 the United States of America and Mexico created the Treaty of Guadalupe Hidalgo. The U.S. paid Mexico 15 million dollars for California and New Mexico. The U.S. also gained present-day Arizona and parts of Colorado, Nevada and Utah. In 1853 during the Gadsden Purchase, the United States bought the lower part of Arizona from Mexico. Mexico had lost close to 55% of its territory because of the war. Mexico had lost its main northern trading town of Santa Fe. To make matters more insulting to Mexico, large of amounts of gold were discovered in California later in 1848 causing one of the biggest gold rushes in modern history.
