History

Keokuk 2
Keokuk (Sauk chief) by George Catlin

Keokuk County was formed in 1837. It was named for the eponymous chief of the Sac Indians, who advocated peace with the white settlers. In May 1843, the county opened for public settlement and was self-governed from 1844. Previously it was governed by Washington County. After a debate lasting a few years for the location for the county seat, the right went to Sigourney in 1856.

Keokuk County is unusual in that it has two county fairs. The Keokuk County Fair is held in What Cheer and immediately followed by the Keokuk County Expo which is held in Sigourney.

The Keokuk County Courthouse in Sigourney was built in 1911. It has been listed on the National Register of Historic Places since 1981.
