Jefferson County, Illinois

The first settler in Jefferson County is believed to have been Andrew Moore. In 1810, he settled near the southeast corner of the county, near where the Goshen Road emerges from the forest of Hamilton County into what is now known as Moore's Prairie. Moore arrived from the Goshen Settlement, near Edwardsville. His migration was therefore retrograde, from the west toward the interior of the State. In 1814, Andrew Moore departed with his eight-year-old son for Jordan's settlement, a journey from which he never returned. A skull that was believed to have been Moore's was found several years later about two miles from his cabin. Jordan's Settlement, also called Jordan's Fort, was southeast of modern Thompsonville, Illinois, about twenty miles south of Moore's cabin. This episode occurred during the War of 1812 when many of the Indian tribes were allied with the British. In 1816, Carter Wilkey, Daniel Crenshaw and Robert Cook settled in Moore's Prairie. Daniel Crenshaw moved into Moore's cabin. This settlement is believed to be the first permanent settlement in the county. Jefferson County was organized in 1819, out of parts of White, Edwards and Franklin Counties. It was named in honor of Thomas Jefferson, principal draftsman of the Northwest Ordinance, among other things. The baseline along the northern border of the County crosses the Third Principal Meridian at the northwest corner of the county.

Jefferson is politically a fairly typical “anti-Yankee” Southern Illinois county. Opposition to the “Yankee” Republican Party and that party's Civil War meant that Jefferson County voted solidly Democratic until Theodore Roosevelt carried the county in his 1904 landslide. It was to again vote Republican in the greater landslides of 1920 and 1928, but otherwise was firmly Democratic until World War II. Following the New Deal, Jefferson became something of a bellwether county, voting for every winning presidential candidate between 1928 and 2004 except in the Catholicism-influenced 1960 election, and that of 1988 which was heavily influenced by a major Midwestern drought. Disagreement with the Democratic Party's liberal views on social issues since the 1990s has caused a powerful swing to the GOP in the past quarter-century: as is typical of the Upland South, Barack Obama in 2012 and Hillary Clinton did far worse than any previous Democrat. ==Communities==
