Mexico - Evolution of the Mexico National Flag and Coat of Arms

The first Europeans to visit the coast were Francisco Fernández de Córdoba in 1517 and Juan de Grijalva in 1518; conquest began in 1519 and Hernán Cortés defeated the Mexica on August 23, 1521. Such is a brief space of time in which this land was brought under the dominion of Spain, which continued to rule over it for the next three hundred years. Growing discontent with Spanish rule led in due course to open revolt, the beginning of which is marked by the issuing of the Grito de Dolores on 16 September 1810; final independence came on 27 September 1821 and the country became an Empire under General Agustín de Iturbide. This, however, was short lived and gave place in 1823 to a republic; in 1864 an empire once more arose under the ill-fated Maximilian, only to be replaced again by a republic in 1867.

In 1968, the national flag was adapted for all purposes: state flag, civil flag, war flag, state ensign, civil ensign and war ensign.

In preparation for the 1968 summer Olympic games, Mexico rewrote its flag legislation not only by designing a new eagle / snake / cactus coat of arms but also by dropping officially the "plain" tricolor and adopted the flag with the arms as the one for all purposes.

By decree of Lic. Gustavo Díaz Ordaz, dated September 17, 1968, the National coat of arms was changed to the current one. It holds some differences to the one decreed by Don Venustiano Carranza in 1916.
Jorge Candeias, 27 Oct 1997, translating from La Bandera Mexicana website

Mexico, since independence was achieved on September 27, 1821, has had 4 (four) National Flags, and if we consider that has been four official decrees abolished each other regarding the flag and five for the coat of arms. It is that to mean that the one adopted in 1823 lasted until 1968 (excepting during the period of the Regency of the Empire and the Empire [1863-1867]), with 5 (five) "official" specifications according the government's in turn judgment, while the coat of arms was redefined or arranged officially 6 (six) times, all in the framework of the 1823-Decree.
It is remarkable that the 1823 Decree by means of which the Second National Flag was adopted was abolished in 1863, readopted in 1867 and last abolished in 1968, year on which the fourth National Flag and fifth coat of arms were adopted.

On the other hand, the Mexico National flag has remained actually the same: a vertical green-white-red tricolor, excepting by the changes granted to the coat of arms, but even the Coat of arms has, in most of the cases, preserved the same elements: eagle, snake, nopal plant, lagoon, and stone. Moreover, unlike other nations in the world, the Mexico National Flag did not modified despite of the government changes and political instability, except for the crown, added to the Mexican coat of arms then to the flag in 1821, and in 1863. However, this brought a huge disorder in drawing and unifying the Mexican symbol through out the nation.
