Now many attribute cannibalistic rituals to the Mesoamericans. Now there is evidence of human sacrifices being part of that culture, but there is no evidence of cannibalism. And many reports of cannibalism against the islanders of the Caribbean and the cultures of the New World were first made by Christopher Columbus himself. So they must be evaluated with a critical eye, as this information was being fed to Europe to depict the inhabitants of the New World as savage animals, justifying genocide. Yet there is some evidence of the practice among some North American Native Americans, mostly as a practice used against defeated enemies. Now the continent of Africa is not immune either, with wartime and starvation being the biggest reasons, although there are examples of it being used in magical ceremonies. Now in the 1970s, the Ugandan dictator Idi Amin was reputed to have practiced cannibalism himself.
