2x3 North Dakota State Flag

The design for the flag of North Dakota is an almost exact copy of the unit banner carried by the state's troop contingent in the Philippine-American War. It was adopted by the North Dakota legislature on March 3, 1911, although the color was not precisely specified at that time. 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.
