Aztec Last Name Generator

The Mexica (Aztecs) did not use hereditary surnames the way Europeans did. A person carried a single Nahuatl name, often taken from the day sign of their birth or a descriptive word, and nobles were known by that name plus the honorific -tzin: Cuauhtemoc, Cacamatzin, Maxixcatzin. Hereditary Aztec last names appeared after 1521, when baptized Nahua families kept a Spanish given name and turned the father's Nahuatl name, his town or his calpulli into a surname. That is why real Mexican surnames like Moctezuma, Xicohtencatl, Cuamatzi, Cahuantzi, Tecuanhuey and Zempoalteca survive in Tlaxcala, Puebla, Morelos and Veracruz today.

Authentic Aztec surnames therefore fall into a few shapes. Some are plain Nahuatl nouns, usually animals or natural things: Coatl (snake), Mazatl (deer), Tototl (bird), Tezcatl (mirror), Xochitl (flower). Some are compounds that were once personal names, such as Itzcoatl (obsidian serpent), Chimalpopoca (smoking shield) or Ilhuicamina (sky archer). Others come from places or peoples and end in -tecatl or -teca: Tlaxcaltecatl, Tepoxtecatl, Zacatelco.

This generator draws on all of those sources, including the ruler lists of Tenochtitlan, Texcoco and Tlatelolco, so you can pair a surname with a Nahuatl or Spanish first name for a historically grounded character or family tree.
