Grant County, North Dakota: History
The territory of Grant County was part of Morton County until 1916. On November 7 the county voters determined that the SW portion of the county would be partitioned off to form a new county, to be named after Ulysses S. Grant, the US President from 1869 to 1877. Accordingly, the county government was organized on November 28, with Carson as the seat. The county's boundaries have remained unchanged since its creation.
