History[]

Greene County is named in honor of General Nathanael Greene, a hero of the American Revolutionary War.^[3] In 1821, three years after Illinois became a state, Green County was established, being carved out of what was previously Madison county and St. Clair county before that. Over the course of the next 18 years four Greene county four more counties were formed out of what was once Greene Country. These include Scott, Morgan, Macoupin and Jersey counties. This left Greene county with approximately 546 square miles of land located in western-central Illinois near the Illinois River, which was an important resource that provided both a means for travel and to ship goods. Like much of southern Illinois the earliest settlers in the county came from the upland southern states such as North and South Carolina, Virginia, Kentucky, and Tennessee. By the time of the Civil War, 1860, the population of Greene County had grown to 16,093 and 10% of the adult population had been born in the northeast, 15% were foreign born, 25% were born in southern states, and almost 50% had been born in the Midwest. Of the population born in the Midwest many could still trace their roots to the upland south, with almost 80% of them having a parents born in a southern state.^[4]

Politics[]

Greene County was reliably Democratic from the beginning through 1948; only one Republican Party nominee carried the county vote during that period. Since then it has usually voted for the Republican presidential nominee (14 of 18 elections).

As one of the most northerly “southern” counties in Illinois, Greene County was rock-ribbed Democratic for the seventy years after the Civil War, which it opposed as a “Yankee” war. Not until considerable anti-Catholic sentiment against Al Smith turned many voters to Herbert Hoover did the county support a Republican presidential nominee. However, with the coming of World War II, opposition to American involvement led to gains for Wendell Willkie and Thomas E. Dewey, although apart from the 1960 election – also influenced by Catholicism – Greene was a bellwether county throughout the period from 1928 to 2004.

In recent years, like most of rural downstate Illinois, opposition to the Democratic Party's liberal views on social issues, along with economic problems, has caused very rapid swings toward the Republican Party. Hillary Clinton’s 2016 tally of 21.68 percent of the county’s vote is 14.3 percent worse than any Democrat presidential candidate before 2012.^[16]
