History
Formed in 1853 from Iroquois County and Will County
An old deed may name a county that no longer exists, or a boundary that has since moved.
Kankakee County was created on April 5, 1853, from Iroquois County and Will County, though the boundaries were somewhat different from the previously proposed county authorized in February 1851. In 1855, Kankakee gained territory from a non-county area attached to Vermilion County.
