Quinatzin

Quinatzin, also called Quinatzin Tlaltecatzin (traditional dates 1252–1331), is named in the native annals preserved by Alva Ixtlilxochitl and the Codex Xolotl as the first tlatoani of the Acolhua city of Texcoco, and the fourth holder of the Chichimec title Chichimecateuctli, 'lord of the Chichimecs'.

His forebears had ruled from Tenayuca; once elected, Quinatzin moved the seat to Texcoco, leaving Tenayuca a place of secondary importance and making Texcoco the centre of Acolhua power. By his wife Cuauhcihuatzin, a noblewoman of Huexotla, he fathered his successor Techotlalatzin and was grandfather of Ixtlilxochitl I.
