Treaty of Guadalupe Hidalgo (1848)(1848) treaty signed by the U.S. and Mexico that officially ended the Mexican-American War; Mexico had to give up much of its northern territory to the U.S (Mexican Cession); in exchange the U.S. gave Mexico $15 million and said that Mexicans living in the lands of the Mexican Cession would be protected This treaty was negotiated by the chief clerk of the State Department, Nicholas P. Trist, after a few failed attempts at an armistice. He signed the treaty on February 2nd, 1848. The treaty was very successful, giving America claim to Texas, and all of the land west of Texas stretching up to Oregon, including California. The U.S. paid $15 million for the land, which increased the size of the country by about 1/3. Some were resentful of the victory over Mexico and the terms of the treaty because they thought that the U.S. should get all of Mexico. Others were angry because they thought Polk hadn't followed the "Anglo-Saxon spirit of fair play."
