"1513 acaxihuitli yn omotlalli altepetl Cuitlaxcolapan quitlalique tlaxcalteca (f. 9) = "1513 Reed year. The city of Cuetlaxcohuapan was established. The Tlaxcalans established it." Another set of annals mention that the Tlaxcalteca elders did not want the new altepetl, Cuetlaxohuapan, to be established at Tlaxcallan. So, instead, it was established at "Atlatoya." Several annals say the establishment of Cuetlaxcohuapan happened in 1531.
