History of Olathe, KS

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.

According to the City of Olathe, the city became the official county seat of Johnson County in October 1859 and has remained so ever since. The 2024 estimated population is approximately 149,035, making Olathe the fourth-most populous city in both Kansas and the Kansas City Metropolitan Statistical Area.
