Becknell contributed to the creation of the Santa Fe Trail by being the first American trader to establish a route from Missouri to Santa Fe, New Mexico in 1821. His successful trade expedition opened up new opportunities for trade between the United States and Mexico, which led to the development of the Santa Fe Trail as a major trade route. Becknell's journey helped paved the way for other traders and settlers to follow the same path, ultimately solidifying the trail's importance in American history.
