Dearborn County was created on March 7, 1803 and was formed from Clark County . The County was named for U.S. Secretary of War Henry Dearborn.
The County Seat is Lawrenceburg. The first Courthouse was half of a double log cabin belonging to Doctor Jabez Percival, one of the associate judges. Lawrenceburg is the County Seat, however, Rising Sun was ambitious to be the County Seat and wanted to have a new county formed, of which it could be the County Seat if it could not wrest the honor from Lawrenceburg. Through this struggle, Lawrenceburg lost the County Seat for a few years. On September 26, 1836, Wilmington became the seat of justice, where it remained until April 1, 1844, when Lawrenceburg again became the County Seat, through an act of the Legislature of January 3, 1844.
