County Seat: Redfield
Square Miles: 1,504
Organized by the Territorial Legislature in 1879, it was named for the Secretary of State of Dakota Territory. History dates back to the Mound Builders perhaps 5,000 years ago, the Rees, then the Sioux. An annual trading fair took place in the early 1800's at Armadale Island. Council Rock to the south was known as the Indian capital of the Dakotas.
A hotly contested election for the county seat nearly caused armed battle between Old Ashton and Redfield until a final election in 1886 gave Redfield the victory.
