The official flag of New Mexico, a subnational polity of the United States, consists of a red sun symbol of the Zia people on a field of gold (yellow). It was officially adopted in 1925 to highlight the state's Native American and Hispano heritage: It combines a symbol of the Puebloan people, who have ancient roots in the state, with the colors of the flag of Spain, which established and ruled Nuevo México for over two and a half centuries. The New Mexico flag is among the most unique and iconic in the U.S., and has been noted for its simple and aesthetic design.
