Treaty of Peace, Friendship, Limits, and Settlement Between the United States of America and the Mexican Republic, 1848

The Treaty of Guadalupe-Hidalgo

The Treaty of Guadalupe Hidalgo ended the war between Mexico and the United States, and established major changes in the relative power of the two nations. In this treaty, a defeated Mexico ceded roughly half of its territory to the United States in exchange for peace and fifteen million dollars. The treaty promised full citizenship to the Mexican residents of the ceded territories, although some Americans considered Mexicans racially inferior and unfit to participate in democracy. The U.S. Congress later rejected the section of the treaty that would have guaranteed the recognition of Spanish and Mexican land titles.
