In 1858, settlers from Lawrence founded the Salina Town Company with a wagon circle, under constant threat of High Plains tribal attacks from the west. It was named for the salty Saline River. Saline County was soon organized around this township, and in 1870, Salina incorporated as a city. As the westernmost town on the Smoky Hill Trail, Salina boomed until the Civil War by establishing itself as a trading post for westbound immigrants, gold prospectors bound for Pikes Peak, and area American Indian tribes. It boomed again from the 1940s-1950s when the Smoky Hill Army Airfield was built for World War II strategic bombers. It is now a micropolis and regional trade center for North Central Kansas.
