endocannibalism

Endocannibalism is the practice of consuming members of one's own family or tribe. This is contrasted with exocannibalism, which is the consumption of individuals from outside one's own group. Cannibalism, in general, is the eating of human flesh by humans and has a long history across various continents.123

Reasons for endocannibalism varied. In some instances, it was a ritualistic act performed by relatives as a sign of respect or love for the deceased, as seen with some Aboriginal Australians and the Fore of Papua New Guinea. It was believed to prevent the body from decaying or being consumed by insects, and to protect against dangerous spirits. In other cases, ritual cannibalism was part of secret societies or religious ceremonies, such as those practiced by the Aztecs. The consumption of specific body parts could also be a ritualistic way to acquire certain qualities of the person eaten.34
