The flag of North Dakota represents the U.S. state of North Dakota. Adopted on March 11, 1911, its design is an almost exact copy of the unit banner carried by the state's troop contingent in the Philippine–American War on a blue field.
The flag design was passed by the North Dakota Legislative Assembly on March 3, 1911, although the color was not precisely specified at that time.[1] Legislation in 1943 brought the flag in line with the original troop banner, which is on display at the North Dakota Heritage Center in Bismarck. The flag also resembles the Great Seal of the United States.
The flag's official proportions are 33:26, significantly shorter than many other state flags; however, in practice, the flag is produced and sold in 5:3 ratios.[2][3] The state code specifies that the flag must be made of blue silk or some other material that is capable of "[withstanding] the elements".[4]
By law, the design of the flag is identical to that carried by the First North Dakota Infantry during the Spanish–American War and the Philippine–American War.[4]
