Between 1821 and 1880, the Santa Fe Trail was primarily a commercial highway connecting Missouri and Santa Fe, New Mexico. From 1821 until 1846, it was an international commercial highway used by Mexican and American traders. In 1846, the Mexican-American War began. The Army of the West followed the Santa Fe Trail to invade New Mexico. When the Treaty of Guadalupe ended the war in 1848, the Santa Fe Trail became a national road connecting the United States to the new southwest territories. Commercial freighting along the trail continued, including considerable military freight hauling to supply the southwestern forts. The trail was also used by stagecoach lines, thousands of gold seekers heading to the California and Colorado gold fields, adventurers, fur trappers, and emigrants. In 1880 the railroad reached Santa Fe and the trail faded into history.

The Pony Express National Historic Trail was used by young men on fast paced horses to carry the nation's mail across the country, from St. Joseph, Missouri to Sacramento, California, in the unprecedented time of only ten days. Organized by private entrepreneurs, the horse-and-rider relay system became the nation's most direct and practical means of east-west communications before the telegraph. Though only in operation for 18 months, between April 1860 and October 1861, the trail proved the feasibility of a central overland transportation route, and played a vital role in aligning California with the Union in the years just before the Civil War.
