The most studied and vilified culture by invaders has been the Mexica. The conquerors had to disproportionately increase the alleged atrocities and the warriors? ability and the power of the "natives", given that it was them who defeated the Aztecs. These false stories increased the alleged heroic deeds and courage developed to defeat the "powerful mexicas". This was totally untrue, because we know that the conquest war was actually a civil war between native peoples, provoked, encouraged and directed by the spaniards, because they used the prophecies that weighed on the Aztec ruling class and their own internal contradictions.

The Tlatócan was the Supreme Council and delegated power on two authorities, one was the Cihuacoátl (female Serpent) engaged in the Administration, and the other in Organization, the Tlatoani (who speaks). These new organizations or "Lordships" faced continuous territorial subjugation and power struggles, making alliances and marriages to consolidate them.
