#5. The inauguration ceremony
The Aztecs had spent years building up the temples in their capital city, and in 1487, the Great Pyramid was complete. They held a massive celebration to inaugurate their great temple—and slaughtered an incredible number of people.The Aztecs claimed that they sacrificed 84,000 people over a period of four days. During the reign of the Aztecs, an estimated 250,000 people were sacrificed across Mexico during an average year.
