History

When in December 1837, a new county was to be split off from the over-large Iowa County, William Boyles of Monroe, as the Representative of the area, was allowed to choose a name. He chose Green County, after the verdant color of the vegetation there. Another member suggested that it be modified to "Greene" after General Nathanael Greene, who commanded the Southern Campaign in the American Revolutionary War but Boyles insisted on his original choice.The story that it was named for General Greene still persists in some circles.

Politics
Until the 1992 presidential election, Green County voters primarily backed the Republican Party candidate in national elections. Prior to that year, the only times they failed to win the county were in the midst of a divided party vote in 1912, the presence of Wisconsinite Robert La Follette on the ballot in 1924, & national Democratic Party landslides in 1932, 1936, & 1964. From 1992 onward, the county has backed the Democratic candidate in every presidential election, though their margins of victory have been often relatively narrow.
