Here is a Cultural Literacy worksheet on the Santa Fe Trail. William Becknell pioneered this road in 1821 as a commercial route between St. Louis, Missouri and Santa Fe, New Mexico (which wasn’t, of course, a state at that time–it became a state in 1912). Along with the freight that moved along this road, inevitably, settlers began to follow. This was the beginning of the United States’ endeavor to help itself to territory that was at the time part of Mexico–which of course culminated in the Mexican-American War.
