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 majority of the area became part of the United States in 1848 at the conclusion of the Mexican-American War (although part had been claimed by Texas in 1836 after becoming independent from Mexico).
