"The apparition of Tecuauhtlacuepeuh (Virgen de Guadalupe) to Juan Diego in Tepeyac [in 1531], at the very place that the [indigenous] Mexicas worshiped the goddess Tonantzin, had a very powerful unifying effect between new world religious beliefs and the old. Tonantzin was the goddess of earth and corn and the name means "our mother" in Nahuatl, the Mexica language.

"La Virgen de Guadalupe" is considered La Reina de Mexico (Queen of Mexico), but the name that she originally gave Juan Diego was Tecuauhtlacuepeuh which in Nahuatl means "She who comes flying from the 'Region of Light' like an 'Eagle of Fire'."

In 1945, Pope Pius XII declared the Virgen de Guadalupe to be the "Empress of the Americas".
