The Aztec people were certain ethnic groups of central Mexico, particularly those groups who spoke the Nahuatl language and who dominated large parts of Mesoamerica from the 14th to the 16th centuries . </P> <P> Aztec culture is the culture of the people referred to as Aztecs, but since most ethnic groups of central Mexico in the postclassic period shared basic cultural traits, many of the traits that characterize Aztec culture cannot be said to be exclusive to the Aztecs . For the same reason, the notion of "Aztec civilization" is best understood as a particular horizon of a general Mesoamerican civilization . The culture of central Mexico includes maize cultivation, the social division between pipiltin nobility and macehualtin commoners, a pantheon (featuring Tezcatlipoca, Tlaloc and Quetzalcoatl), and the calendric system of a xiuhpohualli of 365 days intercalated with a tonalpohualli of 260 days . Particular to the Aztecs of Tenochtitlan was the Mexica patron God Huitzilopochtli, twin pyramids, and the ceramic ware known as Aztec I to III . </P>
