How long did the aztecs live?
The Aztecs, or more properly, the Mexicas, for whom the later Republic of Mexico was named, were a Mesoamerican people of central Mexico in the 14th, 15th and 16th centuries. They were a civilization with a rich mythology and cultural heritage. Their capital was Tenochtitlan, built on raised islets in Lake Texcoco – the site of modern-day Mexico City. The Aztec empire produced the biggest demographic explosion in Mesoamerica: the population grew from an estimated 10 million to 15 million.
