In 1786 Fort Finney was situated where the Kennedy Bridge is today to protect the area from Native Americans, and a settlement grew around the fort. The fort was renamed in 1791 to Fort Steuben in honor of Baron von Steuben. In 1793 the fort was abandoned. Precisely when the settlement became known as Jeffersonville is unclear, but it was probably around 1801, the year in which President Thomas Jefferson took office. In 1802 local residents used a grid pattern designed by Thomas Jefferson for the formation of a city. On September 13, 1803, a post office was established in the city. In 1808 Indiana's second federal land sale office was established in Jeffersonville, which initiated a growth in settling in Indiana that was further spurred by the end of the War of 1812.
