The Treaty of Guadalupe Hidalgo was extremely important for both the United States and Mexico. This treaty was signed in order to mark the end of the Mexican-American War in 1848.
The treaty gave $15 million USD to Mexico. However, it also led to an enormous loss of territory for Mexico. Mexico gave up the land that nowadays corresponds to half of New Mexico, most of Arizona, Nevada, and Utah and Colorado. It also gave American citizenship to many of the people in those areas.
The adoption of such large numbers of people brought a cultural change to the United States. Moreover, the country also adopted many of the cultural practices that were common in these regions. The treaty had a large effect on the future of the country, as it pushed the agenda of imperialism and Manifest Destiny.

With the defeat of its army and the fall of its capital, Mexico entered into negotiations to end the war. The treaty called for the U.S. to pay US$15 million to Mexico and to pay off the claims of American citizens against Mexico up to US$5 million. It gave the United States the Rio Grande as a boundary for Texas, and gave the U.S. ownership of California and a large area comprising roughly half of New Mexico, most of Arizona, Nevada, and Utah, and parts of Wyomingand Colorado. Mexicans in those annexed areas had the choice of relocating to within Mexico's new boundaries or receiving American citizenship with full civil rights.
The U.S. Senate advised and consented to ratification of the treaty by a vote of 38–14. The opponents of this treaty were led by the Whigs, who had opposed the war and rejected Manifest destiny in general, and rejected this expansion in particular. The amount of land gained by the United States from Mexico was increased as a result of the Gadsden Purchase of 1853, which ceded parts of present-day southern Arizona and New Mexico to the United States.
