Techotlalatzin

Techotlalatzin (c. 1323–1409) was tlatoani of the Acolhua city-state of Texcoco from 1357 or 1377 until his death, succeeding his father Quinatzin. The native annals gathered by Torquemada and Alva Ixtlilxochitl present him as the first Acolhua ruler to embrace the culture of the Valley of Mexico, adopting Nahuatl at his court.

He built a small Acolhua domain on the eastern shore of Lake Texcoco, though within the orbit of Tezozomoc of Azcapotzalco, the Tepanec ruler whose city dominated the Valley. His son Ixtlilxochitl I inherited the throne and the quarrel: Tezozomoc defeated and killed him in 1419 and seized Texcoco.
