During the pre-Columbian era, human sacrifice in Maya culture was the ritual offering of nourishment to the gods. Blood was viewed as a potent source of nourishment for the Maya deities, and the sacrifice of a living creature was a powerful blood offering. By extension, the sacrifice of a human life was the ultimate offering of blood to the gods, and the most important Maya rituals culminated in human sacrifice. Generally only high status prisoners of war were sacrificed, with lower status captives being used for labour.
