Ahuachpitzactzin.

a personal name; e.g. don Carlos Ahuachpitzactzin was a Tetzcocan noble who was active in the battles shortly after the Cortés expedition came into central Mexico; he assumed the rule in Tetzcoco after Coanacochtzin; but he was not a strong supporter of Cortés, so the Captain had Coanacochtzin re-installed in place of the younger brother (central Mexico, early seventeenth century)
