Mexican flag is full of national symbolism. The green strip represents the Independence Movement. The white stripe represents the purity of the Catholic faith. The red stripe represents the Spaniards that joined in the quest for Independence and the blood of the national heroes. The emblem-shield symbolizes the Aztec heritage.
