It began in eighteen forty-six. A force known as the Army of the West used the Santa Fe Trail to protect American traders. It also used the trail to take control of an area that is now New Mexico and part of California. The Treaty of Guadalupe Hidalgo ended the Mexican-American war in eighteen forty-eight. It gave the United States nearly all of what is today the states of California, Nevada, Utah, Arizona, Colorado and New Mexico.

这场战争始于1846年，一支美国西部的军队试图保护行走在圣达菲路上的商人，这支军队也试图利用这条路来控制现在是新墨西哥和部分加利福尼亚的地区。1848年， Guadalupe Hidalgo 条约结束了美墨战争，这份条约给予美国现在的加利福尼亚州、内华达州、犹他州、亚利桑那州、科罗拉多州和新墨西哥州的领土。
