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.
In 1845, America tried buying huge parts of Mexican land that included present day California and New Mexico. When Mexico refused to part with its land, America tried using force. Mexico and America both maintained that the border was theirs. This led to the beginning of the Mexican America War that would last for two years (1846-48). America won the war decisively. Mexico had to give up California, New Mexico, Utah, Nevada and parts of Colorado, Wyoming and Arizona.
