Mexican Flag Meaning:
The stripes on Mexico's flag are believed to represent the following: The green stripe represents hope; the white represents symbolizes religion; and the red represents independence and the unity of the nation. Mexico's coat of arms depicts an ancient Aztec legend that tells a tale of God telling a band of wandering Aztec Indians that when they came across an eagle eating a snake while perched on a nopal cactus growing out of a rock surrounded by water, they were to create their home. This spot eventually became Mexico City. This scenario with the eagle eating a snake is depicted on the Mexican coat of arms.
