From 1846 to 1848 the United States fought a war with Mexico. North Americans now know the conflict as the Mexican War, or the Mexican-American War. As a result of the war, the United States took over the land that later became New Mexico, Utah, Nevada, Arizona, California, Texas, and western Colorado.
The Mexican-American War Begins On April 25, 1846, Mexican cavalry attacked a group of U.S. soldiers in the disputed zone under the command of General Zachary Taylor, killing about a dozen. They then laid siege to an American fort along the Rio Grande.
