History of Johnson County

Johnson County was organized in 1812 out of Randolph County. It was named for Richard Mentor Johnson, who was then a U.S. Congressman from Kentucky. In 1813, Johnson commanded a Kentucky regiment at the Battle of the Thames, after which he claimed to have killed Tecumseh in hand-to-hand combat. Johnson went on to become Vice President of the United States.
