History of Waukesha County

Early Days and Native American Tribes

Long ago, the land that is now Waukesha County was covered in forests and prairies. Many Native American tribes lived here, including the Menomonie, Ojibwe (Chippewa), Potawatomi, and Ho-Chunk (Winnebago). They farmed the land and traded goods with each other.

In 1836, these tribes lost their rights to the land. Treaties were ignored, and the U.S. Army forced them to leave. Before the 1830s, few settlers lived here because it was inland. The Fox River was not a major travel route for boats.

First Settlers and County Formation

The first European settlers came from New England. They set up trading posts between their new camps and bigger cities like Milwaukee. Morris D. Cutler and Alonso Cutler were the first permanent white settlers. They came to claim land for their homes.

The area was first part of Michigan Territory and then Wisconsin Territory. In January 1846, Waukesha County was officially created from part of Milwaukee County. Curtis Reed was the first leader of the county. When it was time to choose a county seat, Waukesha won by just two votes over Pewaukee.

The name "Waukesha" comes from a Potawatomi word meaning 'fox'. This is because the streams in the southern part of the county flow into the Fox River.

New England Influence

Many of Waukesha's first settlers were "Yankees" from New England. They came from places like Connecticut, Massachusetts, Vermont, New Hampshire, and Maine. Others came from upstate New York, whose parents had moved there from New England. These people were descendants of the English Puritans who settled New England in the 1600s.

They moved west into the Northwest Territory in the early 1800s. Many arrived after the Erie Canal was finished and the Black Hawk War ended. These New Englanders built farms, roads, and government buildings. They also set up mail routes.

They brought their values with them, like a strong belief in education. This led to many schools being built. They also strongly supported ending slavery. Most were members of the Congregationalist Church. Some later became Methodists or Baptists. For a long time, Waukesha kept a lot of its early New England culture. Later, many German immigrants moved to Wisconsin in the late 1800s.

In 2024, a very old sea creature called a trilobite was named Waukeshaaspis after the county.

Geography and Nature

Waukesha County covers about 581 square miles. Most of this is land (550 square miles), and about 31 square miles (5.3%) is water. The Fox River flows through the county.

The county is located west of Milwaukee. The building of Interstate 94 in Wisconsin helped the area grow with many new neighborhoods and towns.
