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 has been practiced by many cultures throughout the world.

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 the victim's "soul matter" or life force, which could be harnessed through its capture.Hutton, J. H. "The Significance of Head-Hunting in Assam." The Journal of the Royal Anthropological Institute of Great Britain and Ireland, vol. 58, 1928, pp. 399–408.

Austronesia

Among the various Austronesian peoples, head-hunting raids were strongly tied to the practice of tattooing. In head-hunting societies, tattoos were records of how many heads the warriors had taken in battle, and was part of the initiation rites into adulthood. The number and location of tattoos, therefore, were indicative of a warrior's status and prowess.

Indonesia and Malaysia In Southeast Asia, anthropological writings have explored headhunting and other practices of the Murut, Kadazan, Dusun (such as Kwijau and Lotud Dusuns), Iban, 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. Headhunting ceased in Nias island during the early 20th century following voluntary mass-conversions to Christianity.

Headhunting was practiced among Sumba people until the early 20th century. It was done only in large war parties. When the men hunted wild animals, by contrast, they operated in silence and secrecy.Hoskins, Janet. The Play of Time: Kodi Perspectives on Calendars, History, and Exchange. Berkeley: University of California Press, c1993 1993. http://ark.cdlib.org/ark:/13030/ft0x0n99tc/ p.312-314 The skulls collected were hung on the skull tree erected in the center of village.

Kenneth George wrote about annual headhunting rituals that he observed among the Mappurondo religious minority, an upland tribe in the southwest part of the Indonesian island of Sulawesi. Heads are not taken; instead, surrogate heads in the form of coconuts are used in a ritual ceremony. The ritual, called pangngae, takes place at the conclusion of the rice-harvesting season. It functions to bring an end to communal mourning for the deceased of the past year; express intercultural tensions and polemics; allow for a display of manhood; distribute communal resources; and resist outside pressures to abandon Mappurondo ways of life.

In Sarawak, the north-western region of the island of Borneo, the first "White Rajah" James Brooke and his descendants established a dynasty. They eradicated headhunting in the hundred years before World War II. Before Brooke's arrival, the Iban had migrated from the middle Kapuas region into the upper Batang Lupar river region by fighting and displacing the small existing tribes, such as the Seru and Bukitan. Another successful migration by the Iban was from the Saribas region into the Kanowit area in the middle of the Batang Rajang river, led by the famous Mujah "Buah Raya". They fought and displaced such tribes as the Kanowit and Baketan.

Brooke first encountered the headhunting Iban of the Saribas-Skrang in Sarawak at the Battle of Betting Maru in 1849. He gained the signing of the Saribas Treaty with the Iban chief of that region, who was named Orang Kaya Pemancha Dana "Bayang". Subsequently, the Brooke dynasty expanded their territory from the first small Sarawak region to the present-day state of Sarawak. They enlisted the Malay, Iban, and other natives as a large unpaid force to defeat and pacify any rebellions in the states. The Brooke administration prohibited headhunting (ngayau in Iban language) and issued penalties for disobeying the Rajah-led government decree. During expeditions sanctioned by the Brooke administration, they allowed headhunting. The natives who participated in Brooke-approved punitive expeditions were exempted from paying annual tax to the Brooke administration and/or given new territories in return for their service. There were intra-tribal and intertribal headhunting.

The most famous Iban warrior to resist the authority of the Brooke administration was Libau "Rentap". The Brooke government had to send three successive punitive expeditions in order to defeat Rentapi at his fortress on the top of Sadok Hill. Brooke's force suffered major defeats during the first two expeditions. During the third and final expedition, Brooke built a large cannon called Bujang Sadok (Prince of Sadok Mount) to rival Rentap's cannon nicknamed Bujang Timpang Berang (The One Arm Bachelor) and made a truce with the sons of a famous chief, who supported Rentap in not recognizing the government of Brooke due to his policies.

The Iban performed a third major migration from upper Batang Ai region in the Batang Lupar region into the Batang Kanyau (Embaloh) onwards the upper Katibas and then to the Baleh/Mujong regions in the upper Batang Rajang region. They displaced the existing tribes of the Kayan, Kajang, Ukit, etc. The Brooke administration sanctioned the last migrations of the Iban, and reduced any conflict to a minimum. The Iban conducted sacred ritual ceremonies with special and complex incantations to invoke god's blessings, which were associated with headhunting. An example was the Bird Festival in the Saribas/Skrang region and Proper Festival in the Baleh region, both required for men of the tribes to become effective warriors.

During the Japanese occupation of British Borneo during the Second World War, headhunting was revived among the natives. The Sukarno-led Indonesian forces fought against the formation of the Federation of Malaysia. Forces of Malaya, Singapore, Sabah and Sarawak fought in addition, and headhunting was observed during the communist insurgency in Sarawak and what was then Malaya. The Iban were noted for headhunting, and were later recognised as good rangers and trackers during military operations, during which they were awarded fourteen medals of valour and honour.

Since 1997, serious inter-ethnic violence has erupted in Indonesian Kalimantan, involving the indigenous Dayak peoples and migrants from the island of Madura. Events have included the 1997 Sanggau Ledo riots, the 1999 Sambas riots, and the 2001 Sampit conflict. During the Sampit conflict in Central Kalimantan, which began in the town of Sampit, at least 400 Madurese were killed and tens of thousands were forced to flee. Some Madurese bodies were decapitated in a ritual reminiscent of the Dayak headhunting tradition.

The Moluccans (especially Alfurs in Seram), an ethnic group of mixed Austronesian-Papuan origin living in the Maluku Islands, were fierce headhunters until the Dutch colonial rule in Indonesia suppressed the practice.

Melanesia

Headhunting was practised 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.Laurence Goldman (1999).The Anthropology of Cannibalism. p.19.

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 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.

New Zealand

In New Zealand, the Māori people preserved the heads of some of their ancestors and certain enemies in a form known as toi moko. They removed the brain and eyes, and smoked the head, preserving the tā moko (moko tattoos). The heads were sold to European collectors in the late 1800s, in some instances having been commissioned and "made to order"."Weather delays return of toi-moko", TNVZ (national news)

Philippines

In the Philippines, headhunting was extensive among the various Cordilleran peoples (also known as "Igorot") of the Luzon highlands. It was tied with rites of passage, rice harvests, religious rituals to ancestor spirits, blood feuds, and indigenous tattooing. Cordilleran tribes used specific weapons for beheading enemies in raids and warfare, specifically the uniquely shaped head axes and various swords and knives. Though some Cordilleran tribes living near Christianized lowlanders during the Spanish colonial period had already abandoned the practice by the 19th century, they were still rampant in more remote areas beyond the reach of Spanish colonial authorities. The practices were finally suppressed in the early 20th century by the United States during the American colonial period of the Philippines.

Taiwan

Headhunting was a common practice among Taiwanese aborigines. All tribes practiced headhunting except the Yami people, who were previously isolated on Orchid Island, and the Ivatan people. It was associated with the peoples of the Philippines.
