Ohio County, Indiana

Ohio county owes its existence to a county seat fight, which had been waged in Dearborn County for many years prior to 1844, when Ohio county was formally organized by an act of the Legislature. There can be no question but that Ohio County was the direct result of the three-cornered struggle between Lawrenceburg, Wilmington and Rising Sun for the honor of being the county seat of Dearborn County. The final outcome of the struggle resulted in an act of the Legislature, passed January 15, 1844, establishing Ohio County, with Rising Sun as its county seat.

The first term of court in Ohio County convened on the second Monday of December, 1844, at which time Asaph Buck was the only resident member of the Ohio County bar. At this first court, Miles C. Eggleston was the President Judge and Samuel Fulton and Thomas H. Gilmore were the Associate Judges.

Ohio County is the smallest county is the state in terms of both area and population. The Ohio County Courthouse was built in the county seat of Rising Sun in 1845. It is a two-story Greek Revival brick building measuring about 60 feet by 40 feet, including the portico supported by Doric pillars. This courthouse is still in use and is the oldest continuously-used courthouse in the state.

Ohio County has two schools managed by a single school corporation. The Ohio County Elementary-Middle School served a total of 636 students during the 2009-2010 school year. Rising Sun High School served a total of 264 students during the same period.
