History
Formed in 1857 from Calhoun County, Jackson County and Riley County
An old deed may name a county that no longer exists, or a boundary that has since moved.
Pottawatomie County was created by Kansas Territory from parts of Calhoun (now Jackson) and Riley counties. In 1860, a small area was lost to Shawnee County, and the following year Pottawatomie became a county in the state of Kansas.
