The Mormon Battalion was a group of over 500 Mormon volunteers who were mustered into service for the Mexican War (1846-1848). Mustered in at Council Bluffs, Iowa, the Mormon Battalion was the answer to President Brigham Young's request of the United States government to provide aid to migrating Mormons. He believed that the Mormons agreeing to help the United States government would, in turn, protect them from groups wanting to persecute them for their religious beliefs. Although the Mormons may have been leery of assisting a government who had not stopped their persecutions at the hands of citizens in Missouri, Brigham Young encouraged the men to organize a battalion as their patriotic duty.

Battalion members carried on various duties, including garrison duty in California and helping to build forts, courthouses, and houses in California. Members of Company A of the Battalion were responsible for opening the first wagon route from California to Utah in 1848. Members of the Battalion were mustered out on July 1847 in California.

The men of the Battalion marched over 2,000 miles, one of the longest military marches in history. They marched from Council Bluffs, Iowa to Fort Leavenworth, Kansas. Then from Santa Fe, New Mexico they marched to San Diego, California.

Mormon men were not the only participants in the Battalion, some wives and over 50 children were also part of the makeup of this group.
