Aztec rule was based upon a system of tribute and fear over the surrounding peoples; every year, they were forced to pay the Aztecs money, goods, and a supply of captives to be sacrificed on the altar. Taking advantage of this resentment of their Aztec overlords, the tiny Spanish force was able to attract a massive army of some 30,000 Mesoamericans of many different tribes.
