Scalping in the context of "Hidatsa"

Headhunting is the practice of hunting a human and collecting the severed head after killing the victim. More portable body parts (such as ear, nose, or scalp) can be taken as trophies, instead. Headhunting was practiced in historic times across parts of Europe, East Asia, Oceania, Southeast Asia, South Asia, Mesoamerica, South America, West Africa, and Central Africa.

The headhunting practice has been the subject of intense study within the anthropological community, where scholars try to assess and interpret its social roles, functions, and motivations. Anthropological writings explore themes in headhunting that include mortification of the rival, ritual violence, cosmological balance, the display of manhood, cannibalism, dominance over the body and soul of his enemies in life and afterlife, as a trophy and proof of killing (achievement in hunting), show of greatness, prestige by taking on a rival's spirit and power, and as a means of securing the services of the victim as a slave in the afterlife.

The practice of human trophy collecting involves the acquisition of human body parts as trophy, usually as war trophy. The intent may be to demonstrate dominance over the deceased (such as scalping or forming necklaces of severed ears or teeth), to humiliate or intimidate the enemy (such as shrunken heads or skull cups), or in some rare cases to commemorate the deceased (such as the veneration of the relics of saints). It can be done to prove one's body count in battle, to boast of one's prowess and achievements to peers, or as a status symbol of superior masculinity. Serial killers' collection of their victims' body parts have also been described as a form of trophy-taking.

While older customs generally included the burial of human war trophies along with the collector, such items have been sold in modern times.
