(from Greek Exo-
, "from outside" and Cannibalism, 'to eat humans'), as opposed to endocannibalism
, is the practice of eating human corpses, most notably their flesh and some organs such as the heart, from people outside one's own community, tribe or social group. Generally it takes the form of ceremonial sacrifices or the ritual consumption of the rival's flesh in order to absorb their vitality or some other valuable trait
, as well as a symbolic expression of the domination of an enemy in warfare
Such practices have been documented in such cultures as the Aztecs
from Mexico, the Carib
and the Tupinamba
from South America.
