     The Missouri Legislature defined boundaries of Highland County during the session of 1842-43, but there was not sufficient population to permit full organization so it remained attached to Linn County for Civil and Military purposes. By 1844 the State Census showed enough population to fully form the county. E.M.C. Morelock, a representative from Highland County, which was still attached to Linn County, had an act approved on February 14, 1845 organizing Sullivan County. The County was named for Revolutionary War Soldier, General Sullivan.

     Many of our local communities were formed between 1845 and 1900, several of the earliest homes in the county still stand today and many of the earliest records from the County's beginning are archived in our County Courthouse. The County Seat is centrally located in Milan, which boasts one of the oldest, original town squares in the area, with some of the buildings being nearly 140 years old.
