The Dakota Territory legislature created the county on January 4, 1873, with lands partitioned from Pembina County. It was named for George I. Foster, a pioneer and member of the Territorial legislature. Its governing structure was not completed at that time, and it was not attached to another county for administrative purposes. Its boundaries were altered in 1881, two times in 1883, and finally in 1885 its boundary was set at the present configuration. Its county organization was effected on October 11, 1883.
