Mercer County
Founded January 13, 1825
Seat Aledo

Mercer County is named for Hugh Mercer (1726–1777), a physician and general during the American Revolution who died from wounds suffered at the Battle of Princeton.
Although the county was created in 1825, its government was not organized for several years; for administration purposes it was attached first to Schuyler County (until 1826), then to Peoria (until 1831), and finally to Warren County. The organization of the county government was completed in 1835, after a large influx of settlers following the Black Hawk War.
