Milwaukee County

The county seat is Milwaukee, the most populous city in Wisconsin. Named after the Milwaukee River, the county was created in 1834 as part of Michigan Territory and organized the following year. The most populous county of the Milwaukee metropolitan area, as well as of the Milwaukee–Racine–Waukesha combined statistical area. Uniquely among Wisconsin counties, Milwaukee County is completely incorporated (i.e, no part of the county has the unincorporated "town" jurisdiction). There are 19 municipalities in Milwaukee County; 10 incorporated as cities and 9 incorporated as villages. After the city of Milwaukee, the most populous in 2020 were West Allis (60,325), Wauwatosa (48,387), Greenfield (37,803), Oak Creek (36,497), and Franklin (36,816).

Portions of what is now Milwaukee County are known to have been inhabited by a number of Native American tribes, including the Sauk, Meskwaki or "Fox", Menomonee, Ojibwe and Potawotami, with elements of other tribes attested as well. In 1818, when the land later to be Wisconsin was made part of Michigan Territory, territorial governor Lewis Cass created Brown County, which at that time included all the land now part of Milwaukee County. It remained a part of Brown county until 1834, when Milwaukee County was created, including the area south of the line between townships eleven and twelve north (i.e., the northern boundary of Washington and Ozaukee counties), west of Lake Michigan, north of Illinois, and east of the line which now separates Green and Rock counties. This territory encompassed all of what are now Milwaukee, Jefferson, Kenosha, Ozaukee, Racine, Rock, Walworth, Washington, and Waukesha counties, as well as large parts of the present-day Columbia, Dane and Dodge counties. Milwaukee County remained attached to Brown County for judicial purposes until August 25, 1835, when an act was passed by the Michigan territorial legislature giving it an independent organization. In 1836, the legislature divided the area south and east of the Wisconsin and Fox rivers into counties, as a consequence reducing Milwaukee County's extent to what is now Milwaukee and Waukesha counties. In 1846 Waukesha County was created by taking from Milwaukee all of the territory west of range 21, reducing Milwaukee County to its present boundaries. The county peaked in its relative importance in Wisconsin in the 1930s–1960s, when about 25% of the state's population resided in Milwaukee County. Its population has been shrinking since 1970.

According to the U.S. Census Bureau, the county has a total area of 1189 sqmi, of which 241 sqmi is land and 948 sqmi (80%) is water. It is the third-smallest county in Wisconsin by land area. It is watered by the Milwaukee, Menomonee, Kinnickinnic, and Root Rivers. The surface is undulating, and the soil calcareous and fertile. • Illustration — The city at the center is Milwaukee.

Milwaukee County is governed through an eighteen-member Board of Supervisors and by an elected county executive. County supervisors, the county executive, and the county comptroller run in nonpartisan elections while other countywide officials, such as the district attorney and sheriff, run in partisan elections. • Office — Officeholder — Party • Executive — David Crowley — | Nonpartisan • Comptroller — Liz Sumner — | Nonpartisan • Sheriff — Denita Ball — | Democratic • Clerk — George Christenson — | Democratic • Treasurer — David Cullen — | Democratic • Register of Deeds — Israel Ramon — | Democratic • Clerk of Circuit Court — Anna Hodges — | Democratic • District Attorney — Kent Lovern — | Democratic

Like most urban counties, Milwaukee County is a Democratic stronghold, having voted for the Democratic presidential nominee in every election since 1960, and in all but four since 1912. However, there have been some notable exceptions. Former County Sheriff David Clarke, while repeatedly nominated and elected as a Democrat, was initially appointed by Republican governor Scott McCallum (the successor of Tommy Thompson), stated that he considered himself nonpartisan, and espoused politically conservative positions. Former County Executive Scott Walker was a Republican member of the Wisconsin State Assembly before being elected county executive in a 2002 special election after Tom Ament's resignation in a county pension scandal, and elected to full terms in 2004 and 2008, though the office of county executive is nonpartisan. Thompson himself won Milwaukee County in his 1994 and 1998 reelection campaigns—to date, the last time a statewide Republican candidate won the county. In May 2019, the Milwaukee County executive became the first local government in the US to issue a declaration stating that racism constitutes a public health emergency.
