Cannibalism in the Americas

Cannibalism in the Americas has been practiced in many places throughout much of the history of North America and South America. The origin of the term "cannibal" comes from the Island Caribs, who were encountered by Christopher Columbus in the Bahamas. Numerous cultures in North America were reported by European explorers and colonizers to have engaged in cannibalism, however these claims are not always reliable since the Spanish used them as part of their justifications for conquest.

At least some cultures have been physically and archeologically proven beyond any doubt whatsoever to have undertaken institutionalized cannibalism. This includes human bones uncovered in a cave hamlet confirming accounts of the Xiximes undertaking ritualized raids as part of their agricultural cycle after every harvest. Also proven are the Aztec ritual ceremonies during the Spanish conquest at Tecoaque. The Anasazi in the 12th century have also been demonstrated to have undertaken cannibalism, possibly due to a drought, as shown by proteins from human flesh found in recovered feces.

There is near universal agreement that some Mesoamericans practiced human sacrifice and cannibalism, but there is no scholarly consensus as to its extent. Anthropologist Marvin Harris, author of Cannibals and Kings, has suggested that the flesh of the victims was a part of an aristocratic diet as a reward, since the Aztec diet was lacking in proteins. According to Harris, the Aztec economy would not support feeding slaves (the captured in war) and the columns of prisoners were "marching meat." Conversely, Bernard R. Ortiz de Montellano has proposed that Aztec cannibalism coincided with times of harvest and should be thought of as more of a Thanksgiving. Montellano rejects the theories of Harner and Harris saying that with evidence of so many tributes and intensive chinampa agriculture, the Aztecs did not need any other food sources. William Arens' 1978 book The Man-Eating Myth claimed that "there is no firm, substantiable evidence for the socially accepted practice of cannibalism anywhere in the world, at any time in history", but his views have been largely rejected as irreconcilable with the actual evidence.

In later times, cannibalism has occasionally been practiced as a last resort by people suffering from famine. Well-known examples include the ill-fated Donner Party (1846–1847) and the crash of Uruguayan Air Force Flight 571 (1972), after which the survivors ate the bodies of the dead. Additionally, there are cases of people engaging in cannibalism for sexual pleasure, such as Albert Fish and Jeffrey Dahmer.
