History

edit

The area's first non-native settlers were mostly from the six New England states.[3] The early nineteenth century saw a wave of westward movement from New England, due largely to completion of the Erie Canal and the end of the Black Hawk War.[4][5]

The area that included present-day Lee County was delineated as St. Clair County in 1809. In 1823, a large section of northern St. Clair County was partitioned off as Fulton County. In 1825, the northwestern portion of that county was partitioned off as Putnam County. In 1831, the area was further partitioned into Jo Daviess County. A section of that county was partitioned off in 1836 as Ogle County, and in 1839 the bottom half of Ogle County was split off as Lee County. It is largely understood that the county's name honors "Lighthorse Harry" Lee, an officer in the American Revolutionary War.[6] An alternative theory suggests the name honors Richard Henry Lee, a member of the Continental Congress (the Declaration of Independence was adopted pursuant to the Lee Resolution).

President Ronald Reagan lived in Dixon as a boy and attended Dixon High School.[7]

Lee County is, together with neighboring Ogle County, the most consistently Republican county in Illinois. It is one of very few counties in the United States to have never supported a Democrat for President since the Civil War. The only occasion when the Republican candidate did not win the county in this time was in 1912, when Theodore Roosevelt carried it while running as a member of the Progressive Party, unofficially known as the "Bull Moose" party.

As of 2018, Lee County is in the 16th congressional district, the 45th legislative district, and the 74th and 90th representative districts.[19]
