Auítzotl (sometimes rendered as 
Ahuitzotl) was the 
Aztec ruler of the city of 
Tenochtitlan.  Perhaps the greatest known military leader of 
Pre-Columbian MesoAmerica, he began his reign by surpressing a 
Huastec rebellion, and then swiftly more than doubled the size of lands under Aztec dominance.  He conquered the 
Mixtec, 
Zapotec, and other peoples from Mexico's Pacific coast down to the western part of 
Guatemala.  Auitzotl also supervised a major rebuilding of Tenochtitlan on a grander scale. 
Auitzotl took power in 1486; his reign was preceded by Tízoc and followed by Moctezuma II.
