The teenage tribal daughter was sacrificed and the small Aztec tribe was banished to the swampy islands.
The city was built on a foundation of sticks, mud/earth, and volcanic rock in the murky waters. This created a large foundation that the city was built upon.
The Tepanecs were the tribe that ruled the land that the Aztecs lived in. The Aztecs were basically a subject to them until when the Tepanecs noticed the growing Aztec empire so they killed their ruler.
After the war against the Tepanecs, the AZtecs had all the land that they owned but later on, the empire grew larger and they extended to the gulf of mexico and farther south.
The rising empire had subjects to 15 million people, the Aztec then were truly powerful.
A great rain came and flooded the city, to prevent more of these, the Aztecs created a dike that surrounded the city and truly showed that they were the greatest engineers in the Americas.
Hernand Cortez was a conquistador that came to find gold but he found a city of gold. He tricked the Aztecs by having them invite him to the city and he held the emperor captive and captured the city.
Soon after Cortez, the empire was destroyed by the conquistador and 90% of the empire was destroyed by famine, disease, and enemy tribes.
