USA HISTORY

Detailed explanation-1: -This treaty, signed on February 2, 1848, ended the war between the United States and Mexico. By its terms, Mexico ceded 55 percent of its territory, including the present-day states California, Nevada, Utah, New Mexico, most of Arizona and Colorado, and parts of Oklahoma, Kansas, and Wyoming.

Detailed explanation-2: -The treaty was signed on behalf of the United States, by Nicholas Trist, the State Department’s chief clerk, and by three Mexican representatives: Luis Cuevas, Bernardo Couto and Miguel Atristain.

Detailed explanation-3: -It stemmed from the annexation of the Republic of Texas by the U.S. in 1845 and from a dispute over whether Texas ended at the Nueces River (the Mexican claim) or the Rio Grande (the U.S. claim).

Detailed explanation-4: -Won by the Americans and damned by its contemporary critics as expansionist, it resulted in the U.S. gaining more than 500, 000 square miles (1, 300, 000 square km) of Mexican territory extending westward from the Rio Grande to the Pacific Ocean.
