The city’s strategic location ultimately contributed to the power and success of the Aztec Empire.

The Founding of Tenochtitlan

The founding of Tenochtitlan is rooted in a powerful legend. According to Aztec mythology, the god Huitzilopochtli guided the Mexica people to find an eagle perched on a cactus, devouring a snake. This vision symbolized the location for their new city, and in 1325, they settled on the small island in Lake Texcoco. The sight of the eagle on a cactus became a central symbol for the Aztecs and is featured on the modern Mexican flag.

Initially, Tenochtitlan was a modest settlement surrounded by water. The Mexica built floating gardens, known as chinampas, to cultivate crops and sustain their growing population. Over time, the city expanded rapidly, with intricate canals and causeways connecting it to the mainland. The strategic location and advanced agricultural techniques enabled Tenochtitlan to thrive, eventually becoming a powerful city-state and the heart of the Aztec Empire.
