who was president of mexico during the mexican american war
Mexican–American War Once the U.S. declared war on Mexico, Antonio López de Santa Anna wrote to the Mexican government, saying he no longer had aspirations to the presidency, but would eagerly use his military experience to fight off the foreign invasion of Mexico as he had before. President Valentín Gómez Farías, a civilian, was desperate enough to accept the offer and allowed Santa Anna to return. Meanwhile, Santa Anna had secretly been dealing with representatives of the U.S., pledging that if he were allowed back in Mexico through the U.S. naval blockades he would work to sell all contested territory to the United States at a reasonable price.[58] Once back in Mexico at the head of an army, Santa Anna reneged on both agreements. He declared himself president once again and unsuccessfully tried to fight off the U.S. invasion.
Treaty of Guadalupe Hidalgo 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 Wyoming and 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.
