|King of Azcapotzalco and Coyoacán|
Maxtla on the throne
His elder half-brother was Tayatzin.
Maxtla was installed as a ruler of Coyoacán. Upon Tezozomoc's death in the year Twelve Rabbit (1426), Tayatzin became a king, but Maxtla seized power at Azcapotzalco, leaving the rulership of Coyoacán to his son Tecollotzin.
Emperor Chimalpopoca of Tenochtitlan allied with Tayatzin, and the two conspired to retake the throne and kill Maxtla. Friendly relations between Tenochtitlan and Azcapotzalco were thus replaced by insults and violent intrigue, apparently involving tit-for-tat assassination attempts. Maxtla sent Chimalpopoca a present of women's clothing.
When Maxtla laid siege to Tenochtitlan in 1428, Chimalpopoca's successor and uncle, Itzcoatl, repelled his forces with the aid of an alliance of city states, including Texcoco under Nezahualcoyotl and many former Tepanec allies, notably Tlacopan. These allied forces sacked Azcapotzalco and Maxtla was personally sacrificed by Nezahualcoyotl.
