History

[edit]

Henry County was formed on January 13, 1825, out of Fulton County, Illinois. It is named for Patrick Henry,[4] Revolutionary War firebrand and champion of individual rights, to whom the slogan "give me liberty, or give me death" is attributed. The county was settled by people from New England and western New York, descendants of English Puritans who settled New England in the colonial era. The New England settlers founded the five towns of Andover, Wethersfield, Geneseo, Morristown and La Grange.[5]

The settlement of Cambridge came about in 1843, when the owner of the land in that area (Rev. Ithamar Pillsbury) dedicated a section of his properties to a town council; lots were sold to incoming settlers, and construction of the town proper began on June 9, 1843. The incoming "Yankee" settlers made Henry County culturally similar to early New England culture.[6][7]

Politics

[edit]

Henry County's political history is fairly typical of many Yankee-settled rural counties in Illinois. After being largely Democratic in its first few elections, the county turned powerfully Republican for the 110 years following the formation of that party. The only time it did not vote Republican between 1856 and 1960 was in 1912 when the GOP was mortally divided and Progressive Theodore Roosevelt won a majority of the county's ballots. In 1964, when the Republican Party nominated the Southern-oriented Barry Goldwater, Henry County voted Democratic for the first time since 1852, but as was typical for Yankee counties it returned to the Republicans with the selection of the more moderate Richard Nixon.

In the 1980s, the transition of the Republican Party into a party largely based around Southern Evangelicals severely alienated its historic Yankee base: Henry County turned to Democrat Michael Dukakis in 1988, and voted Democratic in every election between 1988 and 2012 except that of 2004 when George W. Bush carried the county by 5.1 percent. However, concern with unemployment and trade deals in the “Rust Belt” resulted in a powerful swing to Republican Donald Trump in 2016 – the worst Democratic result in the county since Jimmy Carter in 1980. In 2020, Trump built on his win in 2016, capturing 60% of the vote - the highest Republican percentage in 40 years.
