History
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.
In May 1812, Congress passed an act which set aside lands in Arkansas, Michigan, and Illinois as payment to volunteer soldiers in the War of 1812. Mercer County was part of this "Military Tract."
Seven years after Illinois became a state, Mercer County was founded. It was formed from unorganized territory near Pike County on January 13, 1825.
