The Santa Fe Trail …

opened on this date in 1821.

William Becknell, under forced escort by Mexican troops, arrives at Santa Fe. New Mexicans, who are still celebrating their newly won independence from Spain, quickly purchase all of his goods, which he initially intended to trade with the Indians. This marked the birth of the Santa Fe Trail, originating from Independence, Mo.
