History
Formed in 1837 from Dubuque County and Cedar County
An old deed may name a county that no longer exists, or a boundary that has since moved.
Keokuk County was created by Wisconsin Territory from Dubuque and Cedar counties in 1837, initially not fully organized and attached to Cedar for temporary purposes. When Iowa Territory was formed from Wisconsin Territory on July 3, 1838, Keokuk became an Iowa Territory county. The county was fully organized and detached from Washington County on March 1, 1844, and became an Iowa county when the state of Iowa was created on December 28, 1846.
