Wichita was founded in 1864 as a trading post on the site of a village of the Wichita Indians. It owed its early development to the  Texas cattle  trade along the Chisholm Trail and to the rapid spread of agricultural settlement along the Atchison, Topeka and Santa Fe Railway, then under construction. In its early years Wichita was a stopover on cattle drives to Abilene (Kansas) and other points as the railroad moved west; in 1872 the line reached Wichita, and the city became a major cattle-shipping centre. By 1875 farmers’ fences were obstructing the movement of beef herds, but grain became an important commodity.
