Linn County is one of the most naturally beautiful and historically significant counties in Kansas. It is particularly well known for its pre-Civil War and Civil War history, which earned this area the name "Bleeding Kansas."
Linn County was home to the original Kansas Jayhawkers, the site of the Marais des Cygnes Massacre, one of the triggers of the Civil War, and the location of the only Civil War battlefield in Kansas.
The confluence of the Marais des Cygnes River and Big Sugar Creek resulted in natural wetlands which are now protected as a wildlife refuge.
The county is now experiencing rapid growth due to its proximity to the Kansas City metropolitan area, and to the US 69 corridor which runs through the eastern part of the county.
