The Aztecs left Atzlan and traveled through the Valley of Mexico working as mercenaries and soldiers. Therefore they were thought of as barbarians Through their travels they saw an eagle on a cactus eating a serpent.
Indeed it has.
The Journey through The Valley of Mexico has been long my friend.
Through their travels the come across a city call Azcapotzalco. They talk to a priest who lives in town.
They talk to the Priest seeking guidance and they tell him about their travels when he says that the eagle wasasign from the gods.
You shall go back the area where you saw the eagle on the cactus eating the serpent and build a town. It is a sign from the gods.
Once they returned they looked around and found a nearby lake with a swampy area around it. This is where they started construction.
Yes we must find the perfect spot.
Let us look for a place to build our city.
They started building in a grid pattern on top of a lake. It was a swampy area so it wasn't very prone to attacks.
This will be a good area to start building
Using their grid pattern they built farms and canals. The farms were floating on the water. In the middle of everything was a temple. After the city was complete they named it Tenochitlan.
