Marion County was created on April 1, 1822 and was formed from Delaware New Purchase. The Delaware New Purchase: Set up in 1820, portions were set apart as the entire counties of Allen, Bartholomew, Hamilton, Henry, Johnson, Marion, Rush, and Shelby. Parts of the counties of Delaware, Hendricks, Madison, and Morgan also were located in the Delaware Purchase. In 1827, the name of the tract was changed to the Adams New Purchase. The County was named for Gen. Francis Marion, the "Swamp Fox" of the American Revolutionary War.
The County Seat is Indianapolis as well as the State Capitol. The original Courthouse, built in 1824, also served as the State Capitol until 1835. This building was often used as a public hall, and for many years was frequently used as a house of worship, until it was torn down in 1870 to make way for its replacement. McCormick's Rock, located on the east bank of the White River, at White River State Park, commemorates the site of John McCormick's cabin. He and two brothers with their families were the first European settlers of Indianapolis. He was one of the first three county commissioners of Marion County and it was in his home that Indianapolis was chosen State Capital. The engineer who laid out the plans for Indianapolis stayed with John Wesley McCormick, Jr. to do his work.
