Ozaukee County, located in Wisconsin, has a rich history dating back to the early 19th century. The region was originally inhabited by Native American tribes, including the Potawatomi and Menominee, who utilized the land for hunting and farming. In the early 1800s, European settlers began arriving in the area, establishing small communities along the Milwaukee River.

The county was officially formed in 1853, taking its name from the Native American word "ozaskeek," meaning "yellow earth" or "fine dust." Agriculture played a significant role in the early economy, with farmers cultivating crops such as wheat, corn, and oats. The Milwaukee River also served as a vital transportation route, enabling trade and commerce to flourish.

The growth of industry in the late 19th and early 20th centuries brought about significant changes in Ozaukee County. The establishment of flour mills, sawmills, and other factories spurred economic development and attracted more settlers to the area. The village of Port Washington, located along Lake Michigan, became an important center for commerce, with its natural harbor serving as a hub for shipping and trade.

Over time, Ozaukee County continued to thrive and adapt to changing times. The construction of highways and railroads further enhanced transportation and connectivity within the region. Today, the county remains a vibrant and dynamic community, with a diverse economy that includes manufacturing, healthcare, and tourism. Its natural beauty, historic sites, and small-town charm continue to attract visitors and residents alike.
