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.

Mitchell County, located in north-central Iowa, has a rich and diverse history dating back to the 19th century. The area was initially inhabited by various Native American tribes, including the Dakota Sioux and Winnebago. The first European settlement in the county occurred in 1851 when Robert Mitchell established a farm along the Winnebago River, eventually leading to the county being named after him in 1855.

The establishment of Mitchell County as an official government entity came in 1854. The county seat was initially located in Osage, which remains the county's largest city. The early years were characterized by the growth of small towns, such as St. Ansgar and Riceville, as well as the development of agriculture as the main economic activity. Immigrants from Europe, particularly Germany, played a significant role in settling the county and contributing to its agricultural development.

By the late 19th century, railroads connected Mitchell County to larger markets, enabling the expansion of trade and the introduction of new industries. The railroad also facilitated the growth of Mason City, a neighboring city that became a significant economic hub for the region. This period also saw advancements in education and infrastructure, including the construction of schools and the improvement of roads.

In the 20th century, Mitchell County faced challenges brought by the Great Depression and changes to the agricultural industry. However, the county managed to adapt and diversify its economy. Manufacturing, healthcare, and tourism emerged as important sectors. Presently, Mitchell County continues to thrive as a picturesque area known for its scenic natural areas, historical sites, and strong sense of community.
