WIS 59

Waukesha County () is a county in the U.S. state of Wisconsin. As of the 2020 United States Census, the population was 406,978, making it the third-most populous county in Wisconsin. Its median income of $88,985 placed it as the only county in Wisconsin on the list of the 100 highest-income counties in the U.S. by median income as of 2020. Its county seat and largest city is Waukesha.

Waukesha County is included in the Milwaukee metropolitan area, and is one of the three WOW counties.

History

The region was first home to Indigenous tribes like Menomonie, Ojibwe (Chippewa), Potawatomi, and Ho-Chunk (Winnebago), who practiced agriculture and trade. In 1836, Native American tribes formally lost title to the land when treaties were disregarded and were forcibly removed by the Federal Army. Prior to the 1830s, the area was unoccupied by settlers due to its inland location and the fact that the Fox River was not a water highway. The New England settlers only came to the area to set up fur trading posts between their new encampments and established cities like Milwaukee. Morris D. Cutler and Alonso Cutler, seeking claims for homesteads, were the first permanent white colonial settlers.

The part of Wisconsin that Waukesha County occupies was a part of Michigan Territory when Milwaukee County was organized in September 1834. On July 4, 1836, the Wisconsin Territory was formed, which included land that is now in the state of Minnesota. In January 1846, part of Milwaukee County was split off into Waukesha County. Curtis Reed was the first county chairman. When a vote decided the county seat, Waukesha defeated Pewaukee by two votes. The name is derived from the Potawatomi word for 'fox' because the streams in the lower part of the county drain into the Fox River.

Waukesha was a New England settlement, and Waukesha's founders were settlers from New England, particularly Connecticut, rural Massachusetts, Vermont, New Hampshire and Maine, as well as from upstate New York who were born to parents who had migrated there from New England shortly after the American Revolution. These people were "Yankees" descended from the English Puritans who settled New England in the 1600s. They were part of a wave of New England farmers who headed west into what was the wilds of the Northwest Territory during the early 1800s. Most arrived as a result of the completion of the Erie Canal as well as the end of the Black Hawk War.

The New Englanders built farms, roads, government buildings and established post routes. They brought many of their Yankee New England values, such as a passion for education that led to the establishment of many schools as well as staunch support for abolitionism. They were mostly members of the Congregationalist Church, though some were Episcopalian. Due to the second Great Awakening some converted to Methodism, and others became Baptists before moving to what is now Waukesha County. Waukesha, like much of Wisconsin, would be culturally very continuous with early New England culture for most of its early history, before the state received a substantial influx of German immigrants in the latter half of the 19th century.

Waukesha County is growing faster than the rest of Wisconsin. In the early 20th century, Waukesha County only contained about 2% of Wisconsin's population. By the year 2000, about 7% of Wisconsin's population was in Waukesha County, and the percentage has grown since.

In 2024, Waukeshaaspis, a prehistoric genus of trilobite, was named after the county.

Geography

According to the U.S. Census Bureau, the county has a total area of 581 sqmi, of which 550 sqmi is land and 31 sqmi (5.3%) is water. The Fox River runs through it.

Waukesha County is located to the west of Milwaukee and its suburban development was spurred by the construction of Interstate 94.

Lake country

Because of its large number of lakes, the northwestern corner of Waukesha County is referred to as "Lake Country" by local residents. It includes Pewaukee, Delafield, Hartland, Merton, Nashotah, Chenequa, Okauchee Lake, Oconomowoc, Summit, and Lac La Belle.

Politics

Waukesha County is the largest Republican-leaning county in Wisconsin and has been one of the most Republican suburban counties in the nation for many years. It is one of the WOW counties, which share similar traits in suburban Milwaukee. Although the county's Republican lean has somewhat lessened since the 2010s, the county is still a Republican stronghold.

It has not supported a Democrat for president since 1964, and has only supported a Democrat four other times since 1892. While other non-Southern suburban counties have moved towards Democrats since the 1990s, Waukesha and the other WOW counties have continued to vote solidly Republican. Underlining this, Lyndon Johnson's narrow win in 1964 is the last time that a Democratic presidential candidate has even garnered 40 percent of the county's vote, though Jimmy Carter, Michael Dukakis, Joe Biden, and Kamala Harris came close. In 2008, John McCain carried the county by a 25.7% margin over Barack Obama, when Obama won Wisconsin by 13.9% over McCain. In 2024, Kamala Harris became the first Democrat since 1976 to lose the county by less than 20 percentage points.

2011 Supreme Court election

The initial unofficial statewide tally in the 2011 Wisconsin Supreme Court election had Democratic challenger JoAnne Kloppenburg defeating incumbent justice David Prosser by a 204-vote margin. On the Thursday after the election, Waukesha County Clerk Kathy Nickolaus reported, among other smaller errors, a failure to report votes in the Waukesha city of Brookfield. The newly reported votes gave Prosser the lead, and he retained his seat. Media reports stemming from this incident referred to the county as "crucial Waukesha County," and the phrase has continued to be widely used in U.S. political media as an in-joke, despite the county being a Republican stronghold.
