1420 CE to 1431 CE
The Mexica of Tenochtitlán have risen from tributary status to de facto allies of Atzcapotzalco by the time of Tezozomoc’s death, for they have now become major tribute gatherers in their own right and serious contenders for power.
Seizing an opportunity for rebellion, the Mexica ally themselves with the Tetzcocoans and a rebellious Tepanec town, Tlacopan, to vanquish Atzcapotzalco.
The victorious allies divide the empire into new spheres of political and economic dominion.
