History

Settlement of the county accelerated after the Black Hawk War and during the era of the Homestead Act precedents that reshaped Midwestern land tenure, attracting settlers from states such as Ohio, Indiana, and Kentucky. The county was named for Francis Marion, a militia officer from the American Revolutionary War whose reputation influenced place names across the United States, similar to counties honoring George Washington, Thomas Jefferson, and Benjamin Franklin. Early economic and social life was tied to riverine routes feeding into the Mississippi River system and later to railroads like the Chicago, Burlington and Quincy Railroad and the Chicago, Rock Island and Pacific Railroad, which spurred town growth. Architectural remnants from the 19th century include structures influenced by styles popular during the Gilded Age and movements tied to the National Register of Historic Places preservation efforts.
