Between 1821 and 1880, the Santa Fe Trail was primarily a commercial highway connecting Missouri and Santa Fe, New Mexico. When the Treaty of Guadalupe Hidalgo ended the war in 1848, the Santa Fe Trail became a national road connecting the United States to the new southwest territories. 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.
