1. Huitzilihuitl was born in Tenochtitlan, and was the son of Acamapichtli, first tlatoani of the Mexica, and Queen Tezcatlan Miyahuatzin, and had a half-brother Itzcoatl.
Only 16 years old when his father died, Huitzilihuitl was elected by the principal chiefs, warriors and priests of the city to replace him.
Huitzilihuitl founded the Royal Council or Tlatocan and established four permanent electors to advise the new king, in his inexperience, at the beginning of each reign.
Huitzilihuitl married Ayauhcihuatl, daughter of Tezozomoc, the powerful tlatoani of Azcapotzalco, and obtained a reduction of tribute payments to the symbolic level.
Huitzilihuitl wanted to introduce potable water into the city, bringing it to the island from the mainland over the brackish water of the lake.
Huitzilihuitl constructed a fort on a rock on the island.
In spite of having given his daughter Matlalchihuatzin in marriage to Ixtlilxochitl, Huitzilihuitl joined his father-in-law in making war on Texcoco.
Huitzilihuitl assisted in the conquest and sacking of the cities of Tultitlan, Cuauhtitlan, Chalco, Tollantzingo, Xaltocan, Otompa and Acolman.
Huitzilihuitl profited from the booty of these conquests and from the traffic of the canoes on the lakes surrounding Tenochtitlan.
Huitzilihuitl died, probably in 1417, before the end of the war between Azcapotzalco and Texcoco.
