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).
From there, the Mexica settled Tenochtitlan, which is modern-day Mexico City. The Aztecs expanded quickly during the 14th and 5th centuries, building canals and settling much of modern-day Mexico. Cortez arrived on the Yucatan peninsula on 1519, and this was the beginning of the end for the Aztec Empire.
