Himno de Marzo

The "Hymn of March" (Spanish: Himno de Marzo) is the name of the official national anthem of Gran Altiplano. The melody was first composed as a naval march in 1893 in Catamarca by a retired officer turned Romantic composer, Federico Valles Constanza. The original march, "Libertad", celebrated the victory of the Catamarqueño Second Fleet over the Hyspanic Navy during the Catamarqueño War of Independence in 1875. It remained in the repertoire of military bands in both Catamarca and Averillas through the middle of the twentieth century at least.

The poem that would be set to the tune originated while its author, Miguel Ángel García, was imprisoned in the infamous island prison El Rincón in the harbour off of Puerto Real as a result of the spring 1976 strikes. A factory worker himself, the poem was quickly triumphed amongst members of the FOC and posted as effective propaganda in Puerto Real and Tarancón. The tune was set to music in the fall of that year, and became in that country the most popular anthem of revolution. As events progressed, it became a similar rallying cry in Averillas, where the conflict remained protracted.

The anthem was formally adopted in Akylaren in Altiplano in September of 1979, having been nominated as such in several issues of La Vanguardia over the summer.
