This settlement on the coastal plain of Veracruz dates from the Epiclassic period, when the Totonac settlements of the previous period lost strength as a result of the weakening of Teotihuacán. As a result of this, the inhabitants of the old settlements gather in small towns with moderate extensions of territory. Quiahuiztlán suffered two invasions in the Postclassic, first by the Toltecs and later by the Mexicas, to whom they remained subject until the moment of Spanish contact. Quiahuiztlán, a settlement very close to the point where Hernán Cortés founded the Villa Rica de la Veracruz, was the place where an alliance was made between the Totonac peoples and the Spanish to conquer the Tenochca empire. Chronology: 800 AD C. to colonial times. Main chronological location: Postclassic, 900 to 1521 AD. c.
