The department played a significant role in the War of 1812, with notable battles including the Battle of Lake Erie and the Battle of New Orleans, led by Andrew Jackson and William Henry Harrison. The department also oversaw the Mexican-American War, which resulted in the Treaty of Guadalupe Hidalgo and the acquisition of a significant amount of new territory, including present-day California, Nevada, Utah, Arizona, New Mexico, Texas, and parts of Colorado, Kansas, Oklahoma, and Wyoming.
