Axayacatl was the
Aztec ruler of the city of
Tenochtitlan who conquered
Tlatelolco, Tenochtitlan's sister city.
Using as a pretext the insulting behavior of a few Tlatelolcan citizens, he invaded his neighbor, killed its ruler and replaced him with a military governor. The Tlatelolcan city council lost any voice it had in forming Aztec policy.
He took power in 1469; his reign was preceded by Moctezuma I and followed by his brother Tízoc.
