County QuickFacts: CensusBureau Quick Facts
Created as Mountraille County by the 1872-73 Dakota Territorial legislature and named for Joseph Mountraille, a Metis voyageur of some prominence, but the boundaries were different from what they are today, extending from the Missouri River north to the border with Canada. It remained a county when North Dakota became a state in 1889, but in 1892 North Dakota Legislature authorized neighboring Ward County to take over all of Mountrail's territory, and the county was eliminated. Its re-establishment as Mountrail County resulted from an effort to partition Ward County during the November 1908 general election which resulted in the county's existence being officially proclaimed on January 25, 1909. Government organized: January 29, 1909. County Seat: Stanley, 1909-present.
