Thanks to television and the movies, the war is probably best known for a battle that did not take place during the Mexican War, the Battle of the Alamo, was actually part of the Texas War for Independence between the "Texicans" and the Mexican government, fought ten years before, in 1836.

From 1846 to 1848, the Mexican War took place between the United States and Mexico after the United States annexation of Texas in 1845, which Mexico still claimed despite the 1836 Texas revolt.

In the United States it is referred to as the Mexican War or the U.S.–Mexican War. In Mexico, it is referred to as "intervención estadounidense en México" (the American intervention in Mexico), "invasión estadounidense de México Americana" (Invasion of Mexico), and "guerra del 47" (The War of '47).

Under the Treaty of Guadalupe Hidalgo, Mexico ceded the territories of Alta California and Santa Fe de Nuevo México to the United States, and accepted the Rio Grande River as the international border, with the loss of Texas.
