History

[edit]

Winnebago County was formed on January 16, 1836, out of Jo Daviess and LaSalle counties. It was named for the Winnebago Tribe of American Indians. At the time the county was founded its inhabitants consisted almost entirely of New Englanders and New England transplants from upstate New York.[2] These were "Yankee" settlers, meaning they were descended from the English Puritans who settled New England during the early 1600s. They made up virtually all of Winnebago County's inhabitants during the first several decades of its history. In this regard the county was similar to most of the northern portion of the state of Illinois, and almost all of the neighboring state of Wisconsin. After the conclusion of the Black Hawk War there was an additional surge of immigration from New England. As a result of this heritage the inhabitants of Winnebago County considered themselves, and functioned as, a cultural expansion of early New England culture.[3] In the presidential election of 1860, Abraham Lincoln won 3,985 votes in Winnebago County, whereas Stephen A. Douglas only won 817 votes.[4]

Politics

[edit]

For many years, Winnebago County was rather conservative for an urban county. From the 1850s to 1988, it backed the Republican candidates for president at every election except the national Democratic landslides of 1936 and 1964. In the 1990s, it became a swing county, backing the national winner in every presidential election from 1992 to 2012, though only three did so with a majority and only once by more than six percentage points. In 2016, Hillary Clinton won the county by only 89 votes over Donald Trump, affected by the relatively large third-party vote that year.

Underlining how Republican Winnebago County once was, only three Democrats have represented a significant portion of the county in Congress since the 1850s.
