Dearborn County was organized in 1803 by Governor William Henry Harrison.  He named the new
                                        county after General Henry Dearborn, who the current Secretary of War (Under President Thomas
                                        Jefferson).  From the original boundaries, six other Indiana counties were carved (in part or in
                                        whole), with the present boundaries being established in 1845.  Dearborn County is made of up 14
                                        townships.

                                        Lawrenceburg was established as the county seat in 1803, at the original formation of the County.
                                        In 826, the original Courthouse, a two story frame building was destroyed by fire.  A new
                                        Courthouse was erected and served as the center of government until 1836, when the county seat
                                        was moved to Wilmington.  Wilmington remained the county seat for only eight years when it was
                                        permanently moved back to Lawrenceburg.  Since 1844, Lawrenceburg has acted as the
                                        uninterrupted seat of government for Dearborn County, with the existing Courthouse being erected
                                        in 1870.

                                        Being a river town, settlers began diverging on Lawrenceburg from their homes in the eastern and
                                        northeastern United States.  There was also a steady immigration of European settlers into Dearborn
                                        County in the mid 1800's, increasing the population of the new county 5 times over.  (In 1815 the
                                        population of the County was 4,424~~~by 1890, the population was over 23,000.)

                                        The Civil War affected Dearborn County in the 1860's when John Morgan Hunt's soldiers marched
                                        through Manchester, Jackson, Kelso, Logan and Harrison Townships, destroying several railroad
                                        bridges.  The years after the war, however, brought stability with the boom in manufacturing and
                                        distilling plants being established in this river town.

                                        Throughout the 19th and early 20th century, Lawrenceburg, Aurora and the surrounding townships
                                        were devastated by Ohio River Floods.  One of the worst occured in January, 1937.  Check out the
                                        Pictorial History of the 1937 Flood in Lawrenceburg.

                                        Dearborn County is 200 years of growth, struggle, change and survival.  Let's visit and see for
                                        ourselves.
