This was an important economic and ceremonial center in the Mexica system of tributes. This is where the tribute was stored, in addition to being a center for making and redistributing cotton products. The modern town covers the majority of the archeological remains. The investigative work on the architectural spaces has led to the conclusion that there were five different phases of construction within the penultimate stage of occupation in the Late Postclassic from 1350 to 1450. The Chontal who settled in towns such as Oztuma, Ixcateopan, Taxco, Tlaxmalac, Chilacachapa and Coatepec Costales were allies with the Matlatzinca in the war against the Mexica during the reign of Moctezuma Ilhuicamina. It is known that the principal activity was trading, in addition to administrative and religious functions. The most important products were: cotton, textiles, salt, corn, pumpkins, chili, cacao, honey, wax, exotic feathers and hides. The ceramics consisted of tripod earthenware pots and pots in the form of stylized snakes.
