Jennings County was created on February 1, 1817 and was formed from Jackson and Jefferson Counties. The County was named for the first Governor of Indiana, Jonathan Jennings.
The County Seat is Vernon, was laid out in 1815 by Colonel John Vawter, and the first settlers were himself and Achilles Vawter; by 1849 it had 35 brick and 65 frame houses with 520 inhabitants. There were attempts to remove the county seat from Vernon, the geographical center of the county, to North Vernon - the most populated city in the county. One reason was that some taxpayers did not want to pay any more money on renovating the courthouse which was built in 1859-61. Another reason was to move it to the more populated town. On July 22, 1919, a special election was held to decide if the seat should be removed. If the vote for removal was 60% or more, the change was to have taken place. On that date, the vote for removal received 2,217 votes (59.6%) and the vote for no removal received 1,512 votes (40.4%). However, there was allegations of illegal balloting and 182 votes were in dispute. The case was taken to court where it linger for 25 years, until in September of 1948 when Judge Fred S. Matthews declared that too much time had elapsed and there was not enough witnesses to verify to the voter irregularity and declared, "Vernon is and remains the county seat of Jennings County." Vernon can claim many firsts: The elevated railroad and underpass, known locally as "the Arch", were the first west of the Alleghenies and are still in use; it also was the first Indiana town to have a public playground; the first all-woman jury trial, held on June 6th, 1921, just after the ratification of the 19th amendment; the first woman's club, the "Clionian Society" established before 1859. With a 2003 population of 319, Vernon is the smallest County Seat in Indiana.
