The Mississippi River is located along the western border of Mercer County and is part of the Yellowbanks Territory, named by the Sauk and Fox Indians because of the yellow, sandy soil along the riverbank. Named after Revolutionary War hero General Hugh Mercer, Mercer County was chartered in 1835 as part of the old Northwest Territory and the Military Tract. As of 2010, the population was 16,434 a drop of 523 from 2000. The county seat is Aledo.
