In the colorful mosaic of Oaxacan festivals and traditions, the Guelaguetza stands out for its deep roots in the Mexican state's cultural identity. The name of this celebration—which takes place every July—traces back to the Zapotec word guendalizaa which refers to the act of making a gift or offering. Its origins date to the pre-Hispanic era and the ritual sacrifices made to the Mexica, or Aztec, goddess Centéotl, the goddess of corn.This annual event became the focus of renewed interest after the Mexican Revolution when the social dynamics in the country led to an intense nationalist campaign to reclaim the country's indigenous past.
