Lee County, Illinois. Located in the northern part of the state, it is part of the Dixon-Sterling Micropolitan Statistical Area. The county was formed in 1839 from territory of Ogle County and LaSalle County and is named for Revolutionary War cavalry officer "Light-Horse Harry" Lee. Its county seat and largest city is Dixon, famously the boyhood home of President Ronald Reagan.
The region was originally inhabited by the Illinois Confederation and later the Sauk and Meskwaki peoples. Following the Black Hawk War of 1832, the area was opened to American settlement, with John Dixon establishing a ferry service across the Rock River in 1830 at what would become the city of Dixon. The county was officially organized in 1839, with its early development tied to agriculture and its position along the river. A significant event was the 1917 arrest and trial of Eugene V. Debs in Dixon for an anti-war speech, a case that went to the Supreme Court of the United States in Debs v. United States. The county is also noted as the site of the 1858 Lincoln-Douglas debates in the community of Amboy.
