The Aztecs, however, were involved in both animal and human sacrifice, and for many different purposes. Human sacrifice often included both self-sacrifice and the sacrifice of other human beings. Self-sacrifice, like bloodletting, consisted of cutting or puncturing oneself, while the other form was simply killing another human. Human sacrifice often involved death by extraction of the heart. Many victims were specifically chosen based on their appearance and their correlation to the gods. Some gods were offered war captives and others with slaves. For Mexica people, “Human sacrifice fulfilled multiple purposes, both at the religious and socio-political level. They considered themselves the “elected” people, the people of the Sun who had been chosen by the gods to feed them and by doing so were responsible for the continuity of the world” (Maestri, 2017). Furthermore, the Aztecs gained so much power in Mesoamerica that human sacrifice added value to political publicity. They required surrounding states to offer human sacrifice as a way of retaining total control. This practice aimed to vanquish neighbors and address a political message to fellow citizens as well as foreign authority. Ancient documents show that human sacrifice also might have been offered for agricultural purposes such as harvest. The Aztecs showed the process most clearly, for an adolescent girl was beheaded at the temple of the maize god in a ceremony performed when the crop was ripe (Watson,
