History
Formed in 1837 from Putnam County
An old deed may name a county that no longer exists, or a boundary that has since moved.
Bureau County was created from Putnam County on April 3, 1837 and named after Pierre Bureau. In 1839, the county gained territory from both Jo Daviess and La Salle Counties, and also received additional land from Putnam County.
