Axayacatl was the ruler of the city of
Tenochtitlan who conquered Tlatelolco
?, Tenochtitlan's sister city.
Using 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.
His reign was preceded by Moctezuma I and followed by his brother Tizoc.
