The flag of Mexico (Spanish: Bandera de México) is a vertical tricolor of green , white , and red with the national coat of arms charged 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 . The form of the coat of arms was most recently revised in 1968, but the overall design has been used since 1821, when the First National Flag was created. Red , white , and green are the colors of the national liberation 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 an eagle sitting on a cactus while devouring a serpent that signaled to the Aztecs where to found their city , Tenochtitlan. A ribbon in the national colors is at the bottom of the coat of arms . Throughout history , the flag has changed several times, as the design of the coat of arms and the length -width ratios of the flag have been modified. However, the coat of arms has had the same features throughout: an eagle , holding a serpent in its talon, is perched on top of a prickly pear cactus ; the cactus is situated on a rock that rises above a lake . The coat of arms is derived from an Aztec legend that their gods told them to build a city where they spot an eagle on a nopal eating a serpent, which is now Mexico City .
