19th century Olathe was founded by John T. Barton in the spring of 1857. He rode to the center of Johnson County, and staked two quarter sections of land as the town site. He later described his ride to friends: "...the prairie was covered with
verbena and other wild flowers. I kept thinking the land was beautiful and that I should name the town Beautiful." Purportedly, Barton asked a
Shawnee interpreter how to say "Beautiful" in his native language. The interpreter responded, "Olathe." Olathe was incorporated in 1857, and while not the first city in Johnson County, its rapid growth led to it being named the
county seat in October 1859. Kansas militia continued to occupy the Olathe military post through the rest of the
Civil War. Confederate forces attempted two further raids against the city. The first happened on August 20–21, 1863, as Quantrill was passing through on his way to
Lawrence, Kansas (see
Lawrence Massacre). The second raid occurred October 24–5, 1864, when Confederate
Major General Sterling Price, with a force of 10,000 men, passed through on their retreat south (see
Price's Raid). With the Confederate surrender, the military post was decommissioned in August 1865. Olathe served as a stop on the
Oregon Trail, the
California Trail, and the
Santa Fe Trail. Catering to travelers was the main source of income for local stores and businesses. The
Mahaffie House, a popular resupply point for wagons headed westward, is today a registered historical site maintained by the City of Olathe. The staff wears period costumes, and stagecoach rides and farm animals make the site a favorite among children. Visitors can participate in Civil War re-enactments, Wild West Days, and other activities. After the construction of the
transcontinental railroad, the trails to the west lost importance, and Olathe faded into obscurity and remained a small, sleepy prairie town.
20th century In the 1950s, the construction of the
interstate highway system and, more directly,
Interstate 35, linked Olathe to nearby
Kansas City, Missouri. The result was tremendous residential growth as Olathe became a part of the Kansas City metropolitan area. In the 1980s, Olathe experienced tremendous commercial growth, which also drew more residents. Olathe's population is estimated to have surpassed 100,000 in 2001, and later projections showed Olathe's growth continuing as the city expanded into the farm fields south, west, and north of town. ==Geography==
