History

Knox County was named in honor of Henry Knox, the first US Secretary of War. [3]

The first "Knox County" in what today is Illinois was unrelated to the modern incarnation. In 1790, the land of the Indiana Territory that was to become Illinois was divided into two counties: St. Clair and Knox. The latter included land in what was to become Indiana. When Knox County, Indiana, was formed from this portion of the county in 1809, the Illinois portions were subdivided into counties that were given other names.

The modern Knox County, Illinois, was organized in 1825, from Fulton County, itself a portion of the original St. Clair County.

Like its neighbor to the south, Fulton County, for its Spoon River Drive, Knox County is also known for a similar scenic drive fall festival the first two weekends in October, the Knox County Drive.

Politics

Knox County's political history is typical of Yankee-settled Northern Illinois. It leaned Whig during its early elections – although giving a plurality to Franklin Pierce in 1852 – and become powerfully Republican following that party's formation. Although Knox did support Progressive Theodore Roosevelt against conservative incumbent President William Howard Taft in 1912, it was Franklin D. Roosevelt’s 1932 landslide before Knox County again gave the Democratic Party so much as a plurality, and it did not give a Democratic absolute majority until Lyndon B. Johnson gained such against the anti-Yankee, Southern-leaning Barry Goldwater in 1964.

Since then, Knox County gradually trended Democratic for the following four decades, so that Michael Dukakis in his losing 1988 campaign was able to carry the county by the same margin as Johnson had done in 1964. During the 1990s and 2000s, Knox was a solidly Democratic county, voting Democratic by at least nine percentage points in every election from 1992 to 2012. The 2016 election, in the shadow of high unemployment in the “Rust Belt” saw a swing of over twenty percentage points to Donald Trump, who became the first Republican victor in the county since Ronald Reagan in 1984.
