History & Politics[]

Ogle County was formed in 1836 out of Jo Daviess and LaSalle Counties, and named in honor of Captain Joseph Ogle, a veteran of the Revolutionary War who came to Illinois in 1785. Ogle did not have an organized government until 1837, so for a year it remained attached to Jo Daviess County. The county was divided three years later in 1839, when Lee County was formed.

Ogle County is one of the most consistently Republican counties in the nation when it comes to Presidential elections. In the last 150 years Theodore Roosevelt's 1912 run as a Progressive was the only time a non-Republican carried the county. No Democratic candidate has ever won the county, which favored the Whig Party before the Republican Party was formed.[2] It is also represented by Republican Donald A. Manzullo as a county in Illinois's 16th congressional district.
