History

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. Rising tensions across the nation over the issue of slavery led to numerous clashes between abolitionist settlers and neighboring slave state Missouri. These clashes further escalated and become a part of the greater conflict known as Bleeding Kansas. With the admission of Kansas into the Union as a free state in 1861, violence began to dissipate. Peace continued to elude Olathe for many years to come, however. In 1861, Union officials and local military forces created a military post in the city. It housed one company of troops along with the local militia.

On September 6, 1862, William Quantrill led a surprise raid of guerrilla Confederates against the city, which resulted in a half dozen deaths and the destruction of most of the city. Quantrill captured the outpost and tried forcing the men to swear an oath to the Confederacy. The oath was deemed invalid in November 1862, since the guerrillas were not considered legitimate enemy military units. 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.

21st century

In 2008, the U.S. Census Bureau ranked Olathe the 24th-fastest growing city in the nation. The same year, CNN and Money ranked Olathe number 11 on its list of the “100 Best Cities to Live in the United States.”
