History
The earliest inhabitants of Linn County, prior to Anglo settlement, were the Sac and Fox tribes. Relations were described by 20th century historians as amicable. Native Americans provided food and furs to whites in exchange for merchandise.<ref>Template:Cite book</ref>
Linn County was created as a named but unorganized area on December 21, 1837, as a part of Wisconsin Territory. It became part of Iowa Territory on July 4, 1838, when the territory was organized.<ref>Template:Cite web</ref> Linn County was organized by the first legislative assembly of the Iowa Territory on January 15, 1839. A site was selected for its first county seat along Indian Creek, and was named Marion, after the Revolutionary War general Francis Marion. As early as 1855, there were debates over moving the county seat to the fast-growing Cedar Rapids, southwest of Marion, but it was not until November 6, 1919, that there were enough votes in favor of the move (9,960 to 4,823).<ref>Template:Cite web</ref> The first rail line was built through Cedar Rapids in 1859, and made the town (and the county) a major commercial hub in eastern Iowa.
Many areas of the county were damaged by the flooding of Cedar River in June 2008, and again during the August 2020 Midwest derecho.
