The Treaty of Guadalupe Hidalgo, signed between Mexico and the United States on February 2, 1848, at the end of the War of American Intervention, established that Mexico ceded to the Americans almost half of its territory, which included the totality of what Today are the states of California, Arizona, Nevada, Utah and part of Colorado, New Mexico and Wyoming. As compensation, the United States paid 15 million dollars for damages to the Mexican territory during the war. Among the aspects of the treaty are the following: the Rio Bravo del Norte or Río Grande was established as the dividing line between Texas and Mexico; the protection of the civil and property rights of Mexicans who remained in the new US territory was stipulated. In addition, the United States agreed to patrol its side of the border, and the two countries agreed to settle future disputes under compulsory arbitration.
