|Died||1426 or 1427/8|
Under his rule the Tlatelolcas continued to expand their wealth and influence within the valley of Mexico. Through trade and tribute, the city's market grew to include trade in wool, jade and quetzal feathers. Tlacateotl also ordered the removal of sculptures from the ruins of Tula to decorate the growing city.
His reign ended in 1426 or 1427/8 during the succession struggle in Azcapotzalco between Tayatzin and Maxtla. He is recorded as having been stoned to death while traveling by canoe. Maxtla is commonly assumed to have ordered the murder, possibly due to a suspected affair between Tlacateotl and Maxtla's wife. He was succeeded by his grandson, Quauhtlatoa.
He succeeded his father, Quaquapitzahuac, upon his death in 1417. He was a brother of the queens Matlalatzin and Huacaltzintli and grandson of the famous king Tezozomoc. He was also a cousin of Emperor Chimalpopoca and uncle of the prince Tezozomoc.
