Flag of Mexico

Flag Ratio: 4:7

The flag of Mexico was first introduced in 1821 as a basic green, white, and red tricolor[?]. In 1823 the Mexican coat of arms[?], which represents the fouding of the Aztec capital Tenochtitlán[?] (now the Mexican capital, Mexico City), was added in the center white stripe. The coat of arms has changed several times since, which has been reflected in modification to the flag.
