Ce Acatl Topiltzin QuetzalCoatl (Our Prince One-Reed Feathered Serpent) is a mythologised figure appearing in 16th-century accounts of Nahua historical traditions, where he is identified as a ruler in the 10th century of the Toltecs— by Aztec tradition their predecessors who had political control of the Valley of Mexico and surrounding region several centuries before the Aztecs themselves arrived on the scene. In later generations, he was a figure of legend often confused or conflated with the important Mesoamerican deity Quetzalcoatl. According to legend in El Salvador, the city of Cuzcatlán (the capital city of the Pipil/Cuzcatlecs) was founded by the exiled Toltec Ce Acatl Topiltzin.
