Corydon is a town in Harrison Township, Harrison County, Indiana, United States, founded in 1808, and is known as Indiana's First State Capital. After Vincennes, Corydon was the second capital of the Indiana Territory from May 1, 1813, until December 11, 1816. After statehood, the town was the capital of Indiana until January 10, 1825, when it moved to Indianapolis. The town remains the county seat of Harrison County and had a population of 3,122 at the 2010 census.
Corydon's history dates to the American Revolution, when the area was captured by George Rogers Clark from the British, bringing it under the control of the fledgling United States.
In the early 1800s Edward Smith brought his family to settle the edge of a fertile valley near a large spring, the site of the today's county fairgrounds. William Henry Harrison, Governor of the Indiana Territory, often stopped to rest at their home while travelling to and from Vincennes. Harrison chanced on the spot where Big Indian Creek and Little Indian Creek join to become the Indian Creek. Tradition says he decided to build a town there and asked Edward Smith's daughter, Jenny, to name it. She chose the name Corydon from Harrison's favorite hymn, the Pastoral Elegy.
