## History

The first American settlement in the area now known as Scott County was Clark's Ferry or Clark's Landing (now Buffalo) in 1833. Other early towns included Davenport (now the county seat and largest city) and the town of Rockingham (which ceased to exist in 1847). The area was fully surveyed in 1837, and the county was established by the Wisconsin territorial legislature in that same year. Scott County is named for General Winfield Scott, who was the presiding officer at the signing of the peace treaty ending the Black Hawk War.
By 1900 the population of the county was 51,500, and by 1950 it was over 100,000. Scott County now comprises part of the Quad City region, which includes the cities of Davenport and Bettendorf (in Iowa) and Rock Island, Moline and East Moline (in Illinois).
The present Scott County Courthouse was completed in 1955 and expanded along with the jail in 2007. The old section of the Scott County Jail was listed on the National Register of Historic Places in 1983. The courthouse was included as a contributing property in the Davenport Downtown Commercial Historic District in 2020.

## Politics

For most of its history, Scott County was primarily a Republican county. From 1880 to 1984, it only supported a Democrat for president nine times, six of which were national Democratic landslides. In more recent elections, the county has become consistently Democratic in presidential elections like many other midsize urban counties nationwide, with the party's candidates winning the county in every presidential election from 1988 on. Despite these victories, their margins of victory have not been as wide as in many other counties of similar composition, especially in 2016 when Hillary Clinton only won the county by 1,291 votes; yet Scott County remains relatively Democratic-leaning. However, in the 2022 elections, Republicans swept Scott County, with the county voting for the Republican candidates for all statewide offices, as well as for Republican Mariannette Miller-Meeks for U.S. House of Representatives. Notably, Republican governor Kim Reynolds won the county with a margin of over 10 points.
In 2024, Republican Donald Trump flipped Scott County in a presidential race for the first time in 40 years when it was won by Ronald Reagan in his landslide 1984 victory.
