 The Aztec, also known as Mexica, periodically sacrificed children as it was believed that the rain god, Tlāloc, required the tears of children.According to Ross Hassig, author of "Aztec Warfare", "between 10,000 and 80,400 people" were sacrificed in the ceremony.The old reports of numbers sacrificed for special feasts have been described as "unbelievably high" by some authors and that on cautious reckoning, based on reliable evidence, the numbers could not have exceeded at most several hundred per year in Tenochtitlan.
