Coles County was organized by on December 25, 1830, from
Clark and
Edgar counties. It was named after
Edward Coles, the second governor of Illinois, from 1822 to 1826. The majority of the American settlers who founded Coles County were either from the six
New England states, or were born in
upstate New York to parents who had moved to that region from New England shortly after the
American Revolution. They were part of a wave of farmers who headed west into the frontier of the
Northwest Territory during the early 1800s. The completion of the
Erie Canal led to an increase in such migrants heading west. When these settlers originally reached what is today Coles County, they found dense virgin forest and prairie. The New England settlers laid out farms, constructed roads, erected government buildings and established post routes. They brought with them many of their "Yankee" values, such as staunch support for
abolitionism as well as a passion for education. They quickly established schools in their communities. They were mostly members of the
Congregationalist Church, though some were
Episcopalian. As a result of the
second Great Awakening, many had become
Baptists or switched to Protestant denominations such as
Methodism or
Presbyterianism before moving to what is now Coles County. The prevalence of settlers with New England heritage resulted in their establishing a culture that was continuous with that of New England for the first several decades of its history. As a result of this, county residents largely supported abolitionism in the antebellum period, and also the Republican Party as of the 1850s and 1860s. Beginning in 1849, numerous German immigrants arrived in Coles County, refugees from the rebellions the year before in various principalities. This population overwhelmingly supported the abolition of slavery. Irish Catholic immigrants who had fled the famine in their country also settled here. Illinois Democratic Senator
Stephen Douglas was extremely popular amongst Irish Catholic immigrants in Coles County at this time. During the Civil War the Irish Catholic community of Coles County would overwhelmingly be
Copperheads.
