In 1889, the Kansas and Arkansas Valley Railroad built a line through this area. It constructed a switch at the present townsite, which it named Comana Switch. A small community sprung up here, which soon became known as Delaware. The name became permanent when a post office was established by that name on March 19, 1898. Discovery of oil nearby in 1904 briefly turned Delaware into a boom town with four thousand residents. However, the bubble burst and the population quickly fell to 108 by November, 1907. The population has fluctuated since then, though generally declining from an official high of 804 in 1920.
