History

In 1803, following Ohio’s admission to the Union, a wedge, or pie shaped, remnant of the former Northwest Territory along Ohio’s southwestern border was ceded to Indiana Territory and organized as Dearborn County. It was named after Henry Dearborn who was U.S. Secretary of War at that time. Lawrenceburg was then designated as the county seat.

All or part of seven other present day counties were carved from the original county with the present boundaries being established in 1845. The region, nicknamed the “Gore”, slices through the present-day counties of Dearborn, Franklin, Ohio, Randolph, Switzerland, Union, Wayne and Fayette. Subdivision of Dearborn County began in 1811 with the formation of Franklin and Wayne Counties, followed by Switzerland in 1814.

Early growth in the region was centered on Lawrenceburg which became an important railroad junction connecting two of the regions major rail lines. A contention existed between the towns of Lawrenceburg and the mostly German-speaking immigrants that dominated Rising Sun over the favored status of Lawrenceburg as the county seat. The rivalry 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 last and smallest Indiana county, county of Ohio on March 1, 1844, with Rising Sun designated as its county seat.
