The New Mexico state emblem is features the ancient Zia sun symbol, which originates from the indigenous Zia people of New Mexico. The symbol is a red circle with groups of four rays pointing in four directions, representing the four cardinal directions, the four seasons, the four periods of the day, and the four stages of life. Adopted in 1925, the Zia sun symbol on the state flag reflects New Mexico's Native American heritage and its reverence for the harmony and balance of life.
