Originally inhabited by indigenous peoples, the county's history began to take shape when European settlers arrived in the early 1800s.

Throughout the late 19th and early 20th centuries, Boone County experienced a number of significant events that shaped its history. In 1880, the Kate Shelley High Bridge was completed, a railway bridge that gained national fame when a young girl named Kate Shelley risked her own life to prevent a train disaster. This event brought national attention to Boone County and solidified its place in American folklore.

In the early 20th century, Boone County faced the challenges brought by the Great Depression and World War II. However, the county rebounded with the help of government programs, and its agricultural sector continued to thrive.
