Huexotla or Huexotla is an archaeological site located 5 kilometers south of Texcoco, at the town of San Luis Huexotla, close to Chapingo, in the Mexico State. Huexotla is considered to hold vestiges of the most important ancient Acolhuacan reign in the east of the Mexico highlands plateau. Huexotla, Coatlinchán and Texcoco were the main Acolhua culture cities and its development began in the 13th century. Texcoco thereby became the second-most important city in the eventual Aztec empire, by agreement receiving two-fifths of the tribute collected.
