Headhunting is the practice of hunting a human and collecting the severed head after killing the victim, although sometimes more portable body parts (such as ear, nose or scalp) are taken instead as trophies. Headhunting was practiced in historic times in 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.
Today's scholars generally agree that headhunting's primary function was ritual and ceremonial. It was part of the process of structuring, reinforcing, and defending hierarchical relationships between communities and individuals. Some experts theorize that the practice stemmed from the belief that the head contained "soul matter" or life force, which could be harnessed through its capture.
Asia and Oceania
Melanesia
Headhunting was practiced by many Austronesian people in Southeast Asia and the Pacific Islands. Headhunting has at one time or another been practiced among most of the peoples of Melanesia, including New Guinea. A missionary found 10,000 skulls in a community longhouse on Goaribari Island in 1901.
Historically, the Marind-anim in New Guinea were famed because of their headhunting. The practice was rooted in their belief system and linked to the name-giving of the newborn. The skull was believed to contain a mana-like force. Headhunting was not motivated primarily by cannibalism, but the dead person's flesh was consumed in ceremonies following the capture and killing.
The Korowai, a Papuan tribe in the southeast of Irian Jaya, live in tree houses, some nearly 40 metres (100') high. This was originally believed to be a defensive practice, presumably as protection against the Citak, a tribe of neighbouring headhunters. Some researchers believe that the American Michael Rockefeller, who disappeared in New Guinea in 1961 while on a field trip, may have been taken by headhunters in the Asmat region. He was the son of New York Governor Nelson Rockefeller.
In The Cruise of the Snark (1911), the account by Jack London of his 1905 adventure sailing in Micronesia, he recounted that headhunters of Malaita attacked his ship during a stay in Langa Langa Lagoon, particularly around Laulasi Island. His and other ships were kidnapping villagers as workers on plantations, a practice known as blackbirding. Captain Mackenzie of the ship Minolta was beheaded by villagers as retribution for the loss of village men during an armed labour "recruiting" drive. The villagers believed that the ship's crew "owed" several more heads before the score was even.
Southeast Asia
In Southeast Asia, anthropological writings have explored headhunting and other practices of the Murut, Dusun Lotud, Ilongot, Igorot, Iban, Dayak, Berawan, Wana, and Mappurondo tribes. Among these groups, headhunting was usually a ritual activity rather than an act of war or feuding. A warrior would take a single head. Headhunting acted as a catalyst for the cessation of personal and collective mourning for the community's dead. Ideas of manhood and marriage were encompassed in the practice, and the taken heads were highly prized. Other reasons for headhunting included capture of enemies as slaves, looting of valuable properties, intra and inter-ethnic conflicts, and territorial expansion.
Italian anthropologist and explorer Elio Modigliani visited the headhunting communities in South Nias (an island to the west of Sumatra) in 1886; he wrote a detailed study of their society and beliefs. He found that the main purpose of headhunting was the belief that, if a man owned another person's skull, his victim would serve as a slave of the owner for eternity in the afterlife. Human skulls were a valuable commodity. Sporadic headhunting continued in Nias island until the late 20th century, the last reported incident dating from 1998.
