The legislature of the Dakota Territory designated Bowman (named for Edward M. Bowman, a member of the territorial House of Representatives during the 1883 session) as a separate county on March 8, 1883, although it was not organized at that time. In 1885, its boundaries were altered to cede territory to Billings and Villard Counties (Villard itself was eliminated in 1887). In 1891, and again in 1896, the South Dakota legislature eliminated the not-yet-organized Bowman County, due to scant settlement in the area, but these actions either were not put into effect (the 1891 vote) or were overturned in judicial appeal (the 1896 vote).
