History
Formed in 1833 from Vermilion County
An old deed may name a county that no longer exists, or a boundary that has since moved.
Champaign County was created from Vermilion County on February 20, 1833. Several attempts were made to create new counties from Champaign County's territory between 1855 and 1867, including proposed counties named Harrison, Holmes, Douglas, and Lincoln, but all required referendums that failed.
