Why was the Santa Fe trail the shortest of all trails?

The Santa Fe Trail was considered the shortest of all major trails because it connected the eastern United States directly to Santa Fe, New Mexico, using a relatively straight path across the plains and mountains. This route minimized the distance compared to other trails that detoured through rugged terrain or followed less direct paths. Established in the early 19th century, it facilitated trade and transportation between the U.S. and Mexico, making it an essential artery for commerce. Its efficiency contributed to its popularity among traders and settlers.
