Corydon has a rich history dating back to the American Revolution when the region was captured by George Rogers Clark from the British, bringing it under the control of the United States.
In the early 1800s the family of Edward Smith moved into land on the edge of a fertile valley near a large spring, now the site of the county fairgrounds. William Henry Harrison, Governor of the Indiana Territory, often stopped to rest at their home while traveling between the east and Vincennes. One day while at their farm, he discovered a spot where the Big Indian Creek and Little Indian Creek join to become the Indian Creek, and decided it would make a good spot for a town. Local legend says that one day he decided that he would build a town on that land and suggested that the family's daughter, Jenny Smith, name the proposed town. Taking the name of a shepherd from Harrison's favorite hymn, called Pastoral Elegy, she chose the name "Corydon". Harrison thought the name was fitting, and thus began the history of Corydon.
