Conquest by foreigners an immediate cause for the collapse of the Aztec civilization.

Historians believe that the Aztec Empire was on a steady decline when the Spanish reached South America.

The Aztecs' most powerful days were already behind them and they had sporadically economic and social problems throughout the empire.
