In the mid-1800s, Iowa was a major hub for the Underground Railroad, a network of secret routes and safe houses used by enslaved African Americans to escape to freedom in the North.
Hardin County, Iowa, located in the heart of the state, has a rich history dating back to its establishment. The county was officially created in 1851 when it was separated from territory that would become Webster County. The area was named after Colonel John J. Hardin, a prominent figure in the Black Hawk War.

The early settlers of Hardin County were mostly farmers looking for fertile land to cultivate. They faced several challenges, including harsh weather conditions and scarcity of resources. Despite these difficulties, the county gradually prospered due to the construction of railroads in the late 19th century, making it easier for goods and people to travel in and out of the area.

Like many other counties in Iowa, Hardin County became a hub for agricultural production, with corn and soybeans being the main crops. The economy of the county was further boosted by the establishment of various manufacturing industries, including meatpacking plants, grain elevators, and furniture factories.

In addition to its economic growth, Hardin County is known for its historical sites and landmarks. One notable attraction is the Eldora City Hall, built in 1874, which is listed on the National Register of Historic Places. Another famous site is the Squirrel Hollow County Park, a popular destination for outdoor enthusiasts, offering camping, hiking, and fishing opportunities.

Today, Hardin County remains a vibrant and flourishing community, preserving its historical heritage while embracing modern advancements. With its beautiful landscapes, strong agricultural roots, and friendly residents, the county continues to be a desirable place to live, work, and visit.
