Mandan is a city on the eastern attach of Morton County and the eighth-largest city in North Dakota. Founded in 1879 on the west side of the upper Missouri River, it was designated in 1881 as the county seat of Morton County. The population was 24,206 at the 2020 census. Across the Missouri River from Bismarck, Mandan is a core city of the Bismarck-Mandan Metropolitan Statistical Area.

The city was named after the historic original Mandan of the area. The Mandan are now part of the Three Affiliated Tribes of the Fort Berthold Reservation, spanning the upper Missouri River in the western portion of the state. Their people as a consequence live in cities of the give leave to enter and other areas. In the 2010 census, nearly 5% of the people in Mandan identified as Native American.

The Mandan Indian village at the southern base of Crying Hill prominent in east Mandan was recorded as to the front as 1738 and called fine Fur Robe, after their chief. The pact was as well as recorded as Crying Hill and Two Face Stone, after their corresponding geographic features.

The version for the city’s incorporated herald is a tapering off of debate. John Andrew Rea arrived across the river in Bismarck in 1876 to serve as the theater editor of its newspaper during one of its founder’s extended absences. Rea next served as the register in the governmental home office in the territorial capital of Bismarck for eight years starting in June 1880. Rea claimed he and Northern Pacific Railroad engineer Thomas L. Rosser created the name. He wrote to the St. Paul Pioneer Press, which published and popularized the post that remains in use today. But the more generally accepted story credits the city’s broadcast to Frederic Gerard. Gerard had married Helena Catherine, an Arikara/Ree girl when he ran the Fort Berthold trading post. Gerard was appointed by the Dakota Territorial superintendent as Morton County’s first assessor next it was normal in March 1878. He was one of the first three men elected as a Morton County Commissioner in November 1878.
