Olathe was founded in the spring of 1857 by Dr. John T. Barton, a physician assigned to the Shawnee tribal headquarters who staked the town site at the geographic center of Johnson County along the Santa Fe Trail. The name comes from a Shawnee word understood to mean ‘beautiful.’ The town was incorporated in 1857 and reincorporated in 1858 due to questions about the legality of the original act.
