TOWNS
Formed in 1821, the county is named after the Sangamon River flowing through it; name is derived from a Pottawatomie Indian word meaning "where there is plenty to eat," or "good hunting ground." Actually, the county was initially named "Sangamo" with the "n" added some time later, for reasons unknown.
Springfield, the State Capital of Illinois, is also the seat of government for Sangamon County.
