Steele County, North Dakota: History
The Dakota Territory legislature created the county on June 2, 1883, with territories partitioned from Griggs and Traill counties. It was not organized at that time but was attached to Traill for administrative and judicial purposes. It was named for businessman Edward H. Steele, who had pushed for its creation.
On June 13, 1883, the county organization was affected and Steele County was detached from Traill County; Sherbrooke, North Dakota was chosen as the county seat. In 1897 the town of Finley was founded, and by 1919 its growth had eclipsed Sherbrooke to the point that the county seat was transferred to Finley. The county's boundaries have been unchanged since its creation.
