History

Formed in 1826 from Clark County and Edgar County

An old deed may name a county that no longer exists, or a boundary that has since moved.

Vermilion County was created from Clark County and non-county area detached from Edgar County on January 18, 1826. Over the following decades, Vermilion County lost territory to the creation of La Salle, Champaign, Iroquois, Will, Livingston, Kankakee, and Ford counties, with the last territorial loss occurring in 1859.
