History

Formed in 1851 from Ramsey County and Washington County

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

Chisago County was created on May 1, 1851 from Ramsey County and Washington County. The county was organized for county government and judicial purposes in 1852. Over subsequent decades, Chisago County's boundaries changed through various attachments and detachments of neighboring territories for judicial and administrative purposes, including exchanges with Pine, Itasca, Benton, Buchanan, St. Louis, and Kanabec counties.
