Most of the ancient civilizations of Mesoamerica such as the Olmec, Maya, Mixtec, Zapotec and Aztec cultures practiced some kind of taking of human trophies during warfare. Captives taken during war would often be taken to their captors' city-states where they would be ritually tortured and sacrificed. These practices are documented by a rich material of iconographic and archaeological evidence from across Mesoamerica.
