History[edit | edit source]

Dearborn County was formed in 1803.[3] It was named for Dr. Henry Dearborn (DR).[4][5] Dearborn was U.S. Secretary of War at the time the County was named. Early growth was centered around Lawrenceburg which was an important railroad junction connecting two of the regions major rail lines.[6]

Dearborn County originally included what is now Ohio County when it was organized in 1803. Lawrenceburg was then designated as the county seat. However, from the start, a contention existed between the towns of Lawrenceburg and Rising Sun over that designation. The contention between the two towns was resolved in 1844 when the Indiana State legislature separated the portion of Dearborn County south of Laughery Creek and created the new county of Ohio on March 1, 1844, with Rising Sun designated as its county seat.[7]

The county government is a constitutional body, and is granted specific powers by the Constitution of Indiana, and by the Indiana Code.

County Council: The county council is the legislative branch of the county government and controls all the spending and revenue collection in the county. Representatives are elected from county districts. The council members serve four-year terms. They are responsible for setting salaries, the annual budget, and special spending. The council also has limited authority to impose local taxes, in the form of an income and property tax that is subject to state level approval, excise taxes, and service taxes.[16][17]

Board of Commissioners: The executive body of the county is made of a board of commissioners. The commissioners are elected county-wide, in staggered terms, and each serves a four-year term. One of the commissioners, typically the most senior, serves as president. The commissioners are charged with executing the acts legislated by the council, collecting revenue, and managing the day-to-day functions of the county government.[16][17]

Court: Dearborn County's courts consist of a Circuit Court (shared with Ohio County in the only such arrangement in the state[18]) and two Superior Courts. Judges are elected to six-year terms. Lawrenceburg and Aurora also have City Courts. Judges there serve four-year terms.

County Officials: The county has several other elected offices, including sheriff, prosecuting attorney, coroner, auditor, treasurer, recorder, surveyor, and circuit court clerk. Each of these elected officers serves a term of four years and oversees a different part of county government. Members elected to county government positions are required to declare a party affiliation and to be residents of the county.[17]
