September in Mexico has a name of its own: el Mes Patrio, the Patriotic Month. For thirty days the country dresses in green, white, and red. Flags hang from balconies and government buildings, street vendors sell paper banners and toy trumpets, and schoolchildren rehearse for ceremonies they will remember the rest of their lives. It all builds toward one night, September 15, and one shout: “¡Viva México!”

Americans know the shout. Fewer know the month behind it: the flag salute every Monday morning, the eagle on the flag and the ancient legend it carries, the anthem schoolchildren sing with their hands over their hearts. Here is a look inside Mexico’s patriotic month, and at the symbols every Mexican student grows up knowing by heart.

A Month, Not Just a Day

Many countries get an independence day. Mexico takes a month. September holds the anniversary of the Grito de Dolores on the 16th, the commemoration of the Niños Héroes, the young cadets who died defending Chapultepec Castle in 1847, on the 13th, and the consummation of independence in 1821 on the 27th. Add the president’s annual address to Congress at the month’s opening, and September becomes a rolling national celebration.

The buildup is visible everywhere. Government buildings are outlined in lights in the national colors. Town squares are decorated, food stalls sell antojitos and the seasonal chiles en nogada, and families plan for the night of the 15th, when the whole country gathers in its plazas for the Grito. By the time the bell rings, Mexico has been warming up for two weeks.

The Eagle, the Serpent, and the Lake

At the center of the Mexican flag stands one of the great national emblems of the world: a golden eagle perched on a prickly pear cactus, gripping a serpent, the cactus growing from an island in a lake. Schoolchildren learn the story behind it before they can read.

According to the founding legend of the Aztec, or Mexica, people, their god Huitzilopochtli told them to leave their homeland and wander until they found a sign: an eagle on a cactus, on an island in a lake. There they were to build their city. They found the sign on an island in Lake Texcoco and built Tenochtitlan, which grew into one of the largest cities on earth. Mexico City stands on its ruins today, and the emblem of that founding moment sits at the center of the national flag. The green stripe is taught as hope, the white as unity, and the red as the blood of the nation’s heroes.

Monday Mornings: Honores a la Bandera

Patriotism in Mexico is not left to September. Every Monday morning of the school year, students across the country line up in the schoolyard for Honores a la Bandera, honors to the flag. A student escort, the escolta, marches the flag in with military precision: six students, drilled and serious, carrying their nation’s banner as if it were made of glass. The student body salutes, the flag is raised or presented, and everyone sings the national anthem.

The anthem, the Himno Nacional Mexicano, has lyrics by Francisco González Bocanegra and music by Jaime Nunó. It was first performed in 1854 and is not a gentle song: its verses speak of war, sacrifice, and a homeland defended at any cost. Generations of Mexican children have sung it every week of their school lives, which is one reason the symbols of September land so deeply. By the time a student reaches the plaza on the night of the Grito, she has been rehearsing her whole life.

A Poem From the Classroom

The verses below come from a poem used in Spanish classrooms to teach the vocabulary of the season. Its young speaker describes exactly what this article has been about: September arriving, the flag with its eagle and serpent, the Monday ceremonies, the anthem sung with pride, and the words written on her heart. It ends the way the month itself ends:

“Al fin llega el mes de septiembre, nuestro mes patrio…” (At last the month of September arrives, our patriotic month…) and finally: “Cada dieciséis de septiembre yo digo: ¡Qué perfecto! ¡Viva México!” (Every September 16 I say: How perfect! Long live Mexico!)

It is a school poem, simple and sincere, and that is the point. In Mexico the love of country is not an abstraction debated by adults. It is a thing children recite on Monday mornings, in uniform, with the flag going up.

Frequently Asked Questions

What does “¡Viva México!” mean?

“Long live Mexico!” It is the closing cry of the Grito ceremony and the signature shout of the September celebrations, answered and repeated by the crowd three times.

Why is there an eagle and a serpent on the Mexican flag?

The emblem comes from the Aztec founding legend of Tenochtitlan: an eagle perched on a cactus on an island in a lake was the sign marking where the Mexica people were to build their city, the site of modern Mexico City.

What are Honores a la Bandera?

The honors to the flag: a short ceremony held every Monday in Mexican schools, in which a student escort presents the flag and the student body salutes it and sings the national anthem.

Is September 16 the only patriotic date in September?

It is the biggest, but the month also includes the Niños Héroes commemoration on September 13 and the anniversary of the completion of independence on September 27, which is why September is called the Mes Patrio, the patriotic month.

The poem above spent years in my own classroom as a September lesson, and I can report that the flag drawing assignment that came with it produced some of the most careful, proud artwork my students ever turned in. Symbols work on us when we handle them. Mexico figured that out a long time ago, and every September it shows.
