Adopted in 1991. The Territory of Nevada was separated from the Utah Territory and incorporated in 1861. Nevada was admitted to the Union as the 36th state in 1864. In both 1864 and 1867 additional land was transferred to the state from portions of the Utah and Arizona Territories. The first 3 flags of Nevada were adopted in 1905, 1915, and 1929. The 1929 flag background color remained blue, but the flag's design changed dramatically. Two sprays of sagebrush crossed to form a wreath in the upper left portion of the flag.
