What territories were gained after the mexican war

The territories gained after the Mexican War for the Americans were Alta California and New Mexico. Before the war, Mexico had not accepted the loss of Texas, but after the war Mexico agreed to this as well as agreeing to the border between the United States and Mexico being the Rio Grande. The United States owed Mexico fifteen million dollars for it's new territorial gains. After several disputes with Mexico, many Mexicans were granted American citizenship if they had been displaced and many of them accepted this offer.
