The exact origins of the Aztec people are uncertain, but they are believed to have begun as a northern tribe of hunter-gatherers whose name came from their homeland Aztlan, or “White Land” in the Aztec language of Nahuatl. The Aztecs were also known as the Tenochca (from which the name for their capital city, Tenochtitlan, was derived) or the Mexica (the origin of the name of the city that would replace Tenochtitlan, as well as the name for the entire country). The Aztecs appeared in Mesoamerica–as the south-central region of pre-Columbian Mexico is known–in the early 13th century. Their arrival came just after or perhaps helped bring about, the fall of the previously dominant Mesoamerican civilization, the Toltecs.
When the Aztecs saw an eagle perched on a cactus on the marshy land near the southwest border of Lake Texcoco, they took it as a sign to build their settlement there. They drained the swampy land, constructed artificial islands on which they could plant gardens and established the foundations of their capital city, Tenochtitlán, in 1325 A.D. Typical Aztec crops included maize (corn), along with beans, squashes, potatoes, tomatoes, and avocadoes; they also supported themselves through fishing and hunting local animals such as rabbits, armadillos, snakes, coyotes, and wild turkey. Their relatively sophisticated system of agriculture (including intensive cultivation of land and irrigation methods) and a powerful military tradition would enable the Aztecs to build a successful state, and later an empire.
