MEXICO FLAG - NATIONAL MEXICAN FLAG POSTCARD

The Flag of Mexico is a vertical tricolor of green, white, and red with the national coat of arms charged in the centre of the white stripe. While the meaning of the colours has changed over time, these three colours were adopted by Mexico following independence from Spain during the country's War of Independence. The current flag was adopted in 1968, but the overall design has been used since 1821, when the First National Flag was created. The current law of national symbols, Law on the National Arms, Flag, and Anthem, that governs the use of the national flag has been in place since 1984. At the time of the flag's adoption, the Italian tricolor was not in use: the flag now contains the coat of arms, in order to distinguish it from that of Italy. Red, white, and green are the colours of the national liberation army in Mexico. The central emblem is the Aztec pictogram for Tenochtitlan (now Mexico City), the centre of their empire. It recalls the legend that inspired the Aztecs to settle on what was originally a lake-island. The form of the coat of arms was most recently revised in 1968. Aztec legend held that they should found their city on the spot where they saw an eagle on a nopal, eating a snake. Ribbon in the national colours are at the bottom of the coat of arms.
