The Mexica Found Their Capital City

Recount how the Mexica followed a divine sign—eagle on cactus—to found Tenochtitlan on a lake island in 1325 CE, growing it into the Americas' most powerful city in Grade 7 history.

Key Concepts

The Mexica people followed a founding legend from their gods. This legend told them to build their capital where they saw an eagle on a cactus holding a snake. This divine sign would mark their new home and the center of their world.

In 1325 C.E., the Mexica found this sign on a swampy island in Lake Texcoco. They founded their city, Tenochtitlán , in this challenging location. What began as a simple refuge soon grew into one of the largest and most powerful cities in the Americas.

Common Questions

What founding legend guided the Mexica to Tenochtitlan's site?

The Mexica followed a divine prophecy that told them to build their capital at the spot where they saw an eagle perched on a cactus holding a snake. This sacred sign would mark the location chosen by their gods as the center of their world. After centuries of wandering, they finally found this sign on a swampy island in Lake Texcoco in 1325 CE.

Why did the Mexica choose such a difficult island location?

The island in Lake Texcoco offered strategic advantages despite its challenges—surrounded by water, it was naturally defensible against enemy attacks. While the swampy ground made construction difficult, the lake provided food through fishing and eventually through chinampas (floating gardens). The divine mandate gave the Mexica determination to overcome the site's practical challenges.

How did Tenochtitlan grow from a simple settlement to a great city?

What began as a small refuge on a lake island grew over the following centuries into one of the largest and most powerful cities in the Americas. The Mexica (Aztecs) built causeways connecting the island to the mainland, constructed massive temples, and drained and filled portions of the lake. By the early 1500s, Tenochtitlan had a population that rivaled the largest European cities.
