Randolph County, Illinois has a rich history that dates back to the early 18th century. The area that is now Randolph County was first explored by French trappers and traders in the late 1600s, but it wasn't until the early 1800s that settlers began to establish permanent communities there. The county was officially formed in 1795 and was named after Edmund Randolph, the first Attorney General of the United States.

In its early years, Randolph County was predominantly an agricultural community. The fertile soil and favorable climate made it an ideal location for farming, and many settlers grew crops such as corn, wheat, and tobacco. The county also had a strong mining industry, with coal being a major natural resource. The combination of agriculture and mining helped to fuel the economy and attract more residents to the area.

During the mid-19th century, Randolph County saw significant growth and development. The construction of railroads in the county connected it to the rest of the state and facilitated the transportation of goods. This led to the establishment of new industries, such as manufacturing and timber production. The county also experienced an influx of immigrants, particularly from Germany and Ireland, who brought new skills and cultural traditions to the area.

In the 20th century, Randolph County continued to evolve and adapt to changing economic and social conditions. The decline of coal mining and agricultural changes led to a shift towards a more diverse economy. Today, the county is known for its tourism industry, with attractions such as the Chester Bridge and Fort de Chartres drawing visitors from across the country. Randolph County also has a strong sense of community, with many residents proud of their heritage and actively involved in preserving the county's history.
