The flag of Missouri consists of a triband of three equal horizontal stripes colored red, white, and blue, with the arms from the Great Seal of Missouri in the center. Designed by Mary Elizabeth Oliver, the red and white stripes represent valor and purity, respectively. The blue stripe represents the permanency, vigilance, and justice of the state. The three colors also highlight the French influence on the state in its early years. The Missouri flag was established on March 22, 1913, when governor Elliot Woolfolk Major signed the State flag act making it official.
