Dia de la Bandera/Flag Day February 24th, 1887

Like in many countries, the Flag is considered the most important symbol. In the Mexican motherland, their Flag is the symbol of unity and sovereignity, designating February 24th to commemorate it since it represents several events of the historic developments of Mexico. As Mexico developed as a Republican and Democratic Country, they thought it necessary to adopt its “own symbols” which represented the cultural and social characteristics of “El Pueblo Mexicano.” Mexico’s National Flag was created in 1821 by the "Three Guaranties" Army, as the Plan of Iguala was proclaimed; the Plan of Iguala promised to establish three guaranties: religion, independence and union. By establishing these three guaranties, they adopted three colors to represent them: green, representing its independence, white representing its purity of religion and red representing the union of Americans and Iberians. This Flag was endorsed by the signatories of the pact of Independence, the Royal Army official Agustín de Iturbide and Vicente Guerrero.During the few years of the First Mexican Empire, there was a law requesting the flag to change position; on the white fringe edges the eagle was settled alone, with its wings open and the head was on the side, wearing the Imperial Crown. But in 1823, the Constitutional Republican Congress ordered that the Emblem must be presented according to the Indian tradition; the eagle on the side and posing on a cactus eating a serpent and without the Imperial Crown.The National Emblem was originally introduced on the flag during the Second Empire of Maximilian of Hapsburg (Emperor of Mexico from Hungarian descent), when a flag with the eagle under the Imperial Crown was adopted. Then, long term dictator President Porfirio Díaz ordered to have the eagle placed in the front with her wings extended. After that, the emblem was changed again by Revolutionary President Venustiano Carranza, who decided to have the eagle placed on its left side and that it kept the Mexicans conception of the founding of Great Tenochtitlan (the old Aztec Mexico City). In addition to this, a tricolor ribbon was included symbolizing the patriotic unity joining the branches of encino and laurel.As of February 24th 1937, the day of the Flag is celebrated at the monument of General Vicente Guerrero, (the first Mexican soldier to swear allegiance to the Flag in the event known as the "holding of Acatempan" of 12 March 1821).
