County of atchison

missouri

History & Founding

Located in the northwest corner of Missouri, this county holds a rich history and a distinct rural character. Established in 1847 from parts of Daviess and Buchanan counties, its creation reflects the westward expansion occurring across the United States. The county’s name honors David Atchison, a prominent Missouri senator and a champion of the Kansas-Nebraska Act. Interestingly, Atchison, during his time in the Senate, often slept during crucial debates, earning him the nickname "Old Bore." Legend has it that when he once awoke during a particularly heated discussion, he mistakenly voted in favor of a measure he vehemently opposed, highlighting the sometimes-chaotic nature of early political life. The county’s early development was intertwined with the Missouri River and the burgeoning trade routes that utilized it.

Covering 545 square miles, its terrain is predominantly flat to gently rolling farmland, typical of the region’s prairie landscape.
