Flag of Mexico

The nationalflag of Mexico (Spanish: bandera nacional de México) is a vertical tricolor of green, white, and red with the national coat of armscharged in the center of the white stripe. While the meaning of the colors has changed over time, these three colors were adopted by Mexico following independence from Spain during the country's War of Independence, and subsequent First Mexican Empire.

Red, white, and green are the colors of the national army in Mexico. The central emblem is the Mexican coat of arms, based on the Aztec symbol for Tenochtitlan (now Mexico City), the center of the Aztec Empire. It recalls the legend of a golden eagle sitting on a nopal cactus while devouring a serpent that signaled to the Aztecs where to found their city, Tenochtitlan.
