Jo Daviess County (/ˈdeɪvɪs/) is the northwesternmost county in the U.S. state of Illinois. According to the 2020 census, it had a population of 22,035.[1] Its county seat is Galena.[2]

Jo Daviess County is part of the Tri-State Area and is located near Dubuque, Iowa and Platteville, Wisconsin. As part of the Driftless Area, Jo Daviess County is known for its scenic stretches of road, high hills and valley views. Within Jo Daviess County lies Charles Mound, the highest natural point in Illinois, as well as eight of the ten highest points in Illinois.[3][4]

History

Jo Daviess County was formed in 1827 out of Henry and Putnam Counties. It is named for Maj. Joseph Hamilton Daveiss, United States District Attorney for Kentucky, who was killed in 1811 at the Battle of Tippecanoe.[5] The local pronunciation is "Davis". Jo Daviess County was founded exclusively by immigrants from New England. These were old stock "Yankee" immigrants, meaning they were descended from the English Puritans who settled New England in the 1600s. The completion of the Erie Canal caused a surge in New England immigration to what was then the Northwest Territory.

The end of the Black Hawk War led to an additional surge of immigration, once again coming almost exclusively from the six New England states as a result of overpopulation combined with land shortages in that region. Some of these later settlers were from upstate New York and had parents who had moved to that region from New England shortly after the Revolutionary War. New Englanders and New England transplants from upstate New York were the vast majority of Jo Daviess County's inhabitants during the first several decades of its history. These settlers 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 Jo Daviess County. The Congregational Church subsequently has gone through many divisions and some factions, including those in Jo Daviess County are now known as the Church of Christ and the United Church of Christ.

As a result of this heritage the vast majority of inhabitants in Jo Daviess County, much like antebellum New England were overwhelmingly in favor of the abolitionist movement during the decades leading up to the Civil War.[6]

In the late 1880s and early 1890s Irish and German migrants began moving into Jo Daviess County, most of these later immigrants did not move directly from Ireland and Germany, but rather from other areas in the Midwest where they had been living, particularly the state of Ohio.[7]

Major highways

In Illinois, US 20 is designated the General Ulysses S. Grant Highway (often abbreviated the U.S. Grant Memorial Highway) and is the longest route in the United States.[12] In eastern Jo Daviess County US 20 is one of the few areas that remain two-lane across the entire stretch of US 20. The road between Dubuque and Stockton was once known as the most dangerous stretch of road because of the hills and curves flanked by cliffs and valleys. Travelers were greeted with signs reminding them to drive carefully as they entered this stretch of road.
