History
Formed in 1821 from Bond County, Clark County and Madison County
An old deed may name a county that no longer exists, or a boundary that has since moved.
Pike County was named after Zebulon Pike. Soon after its creation, Pike County underwent significant boundary changes, losing territory to the creation of Fulton, Calhoun, Adams, Schuyler, Hancock, Mercer, and Warren Counties between 1823 and 1825.
