History

Unlike most of Illinois, much of Northern Illinois was not submerged in a shallow prehistoric sea. As a result, bedrock found in the area now bounded as Boone County is almost entirely Ordovician, as opposed to nearby counties like McHenry and Carroll which contain large areas of later Silurian bedrock. Till and outwash from the Illinoian glaciation covers area bedrock to a depth of several hundred feet. The county's proximity to the driftless area protected the region somewhat from the more recent Wisconsin glaciation. As a result, the county's northern townships resemble a driftless-like area, with higher peak elevations and more surface detail compared to the southern townships dominated by the broad flood plains of the Kishwaukee River and its tributaries.

By the time of the first identified human settlements, the region was made up of thickly wooded forested hills and grassy prairie plains. Archeological study at the Koster Site seems to indicate that humans had established complex societies ten thousand years ago along the river basins of the Illinois and Mississippi. By the time of European exploration, Upper Mississippian culture collapsed; westward expansion forced many Algonquin-speaking nations into conflict with each other as they moved after encroachment of their lands. Potowatomi and Mascouten tribes were still living in the region when white settlers arrived and statehood was declared in 1818.

As a political institution, Boone County was formed on March 3, 1836, out of Winnebago County. It was named for Kentucky frontiersman Daniel Boone.
The first non-Native American settlers arrived in what is now Boone County in 1835. They arrived as a result of the end of the Black Hawk War as well as the completion of the Erie Canal. They consisted entirely of settlers from New England. These were "Yankee" settlers, that is to say they were descended from the English Puritans who settled New England in the colonial era. They were primarily members of the Congregational Church though due to the Second Great Awakening many of them had converted to Methodism and some had become Baptists before coming to what is now Boone County. When the New England settlers arrived in what is now Boone County there was nothing but a dense virgin forest and wild prairie. In the late 1870s immigrants began arriving from Germany and Ireland.

Politics

As a historic Yankee settlement, Boone County in its early years was a major base for the Free Soil Party, being one of nine Illinois counties to vote for Martin van Buren in 1848. Its Free Soil affinities meant Boone became one of the first strongholds of the Republican Party and remained overwhelmingly Republican for the following century, although it did vote for Progressive Theodore Roosevelt in 1912 when the Republican Party was severely split. Between at least 1892 and 1928 no Democratic presidential candidate ever managed twenty percent of the county's vote, and in the century up to 1960 no Democrat reached thirty percent – a degree of GOP loyalty comparable to such famous bastions as Owsley County in Kentucky, Grant County in West Virginia, or Avery County in North Carolina. Even Barry Goldwater, who alienated the Yankee Northeast so much as to lose all but one county there, still won Boone County by 15.6 percentage points, and between 1968 and 1988 no Democrat did better than Jimmy Carter’s 40.2 percent.

The shift of the Republican Party towards an expanded Southern and Western base, and particularly its growing strength with social conservatives, alienated the Yankee North during the 1990s and 2000s, but Boone County remained in Republican hands. The candidacy of Ross Perot in 1992 and 1996 caused George H. W. Bush and Bob Dole both to win Boone County with mere pluralities against Bill Clinton, and in 2008, Illinois resident Barack Obama became the only Democrat to carry the county since James K. Polk in 1844. The 2010s have seen a reversal of this Democratic trend due to concern over employment declines in the “Rust Belt."
