Harrison County, Indiana: History
Humans first entered what would become Indiana near the end of the last ice age. This region was of particular value to the early humans because of the abundance of flint. There is evidence of flint mining in local caves as early as 2000 BCE; the stone was used to produce crude tools. Passing migratory tribes frequented the area which was influenced by succeeding groups of peoples including the Hopewells and Mississippians. One flint-working and camping location is the Swan's Landing Archeological Site, one of the most important Early Archaic archaeological sites in eastern North America. Permanent human settlements in the county began with the arrival of American settlers in the last decade of the 18th century.
The area became part of the United States following its conquest during the American Revolutionary War. Veterans of the revolution received land grants in the eastern part of the county as part of Clark's Grant. Daniel Boone and his brother Squire Boone were early explorers of the county, entering from Kentucky in the 1780s. Harvey Heth, Spier Spencer, and Edward Smith were among the first to settle in the county beginning in the 1790s. Smith built the first home in the area of Corydon.
Harrison County was originally part of Knox County and Clark County but was separated in 1808. It was the first Indiana county formed by the Indiana territorial legislature instead of the Governor, and the fourth to be formed in the future state of Indiana (after Knox and Clark; also Dearborn County was formed in 1803 when the eastern territory borderline with Ohio was adjusted to transfer the "Gore" to Indiana Territory). Portions of the county were later separated into parts of Crawford, Floyd, Washington, Jackson, Clark, Lawrence, Perry, Scott and Orange Counties. The county was named for William Henry Harrison, the first governor of Indiana Territory, a General in War of 1812, hero of Tippecanoe, and the 9th U.S. President. Harrison was the largest land holder in the county at the time and had a small estate at Harrison Spring. …
