Kenosha County, Wisconsin: History
The Potowatomi inhabited the area that would become Kenosha County for centuries prior to the acquisition of the area in 1833. The city of Kenosha was founded in 1835, and Kenosha County was formed from Racine County on January 30, 1850. Its location led to development and factories being built in the 19th century. Manufacturing continued to be a key component of the economy into the 20th century.
