Matsigenka

The Matsigenka (also written Machiguenga, Matsigenga, Matsiguenga) are an Arawak-speaking people of south-eastern Peru, living on the eastern Andean slope and the adjoining lowland forest. The word matsigenka means human being, person, people — it names those who possess a human soul, and is used in contrast to spirits, animals and outsiders. Their homeland spans the Urubamba basin in Cusco and the Manu and Madre de Dios basins, with smaller registered populations in Ucayali, Ayacucho and Lima. Population figures are genuinely contested and should be read with care. The 2017 national census recorded 5,982 people self-identifying as Matsigenka by custom or ancestry and 6,629 declaring the language as their childhood tongue, while the Ministry of Culture's BDPI counts roughly 18,933 people living in 111 registered Matsigenka localities, 57 of them titled native communities; general reference works give figures near 18,000. The gap reflects how each source counts — self-identification, language, or residence in a recognised locality. Origin narratives centre on the Pongo de Mainique, the gorge where the Urubamba cuts the last Andean ridge. Ethnographers, notably Allen Johnson, have described a society organised around the autonomy of the individual household, dispersed settlement, restraint in speech, and generosity as a moral obligation; personal names were traditionally little used, with kin terms and nicknames doing the work instead. Campa, long applied by outsiders to Arawak peoples of this region, is a pejorative exonym and should not be used.

Matsigenka territory runs from cloud forest on the Andean flank down into lowland terra firme forest, drained by the Urubamba and its tributaries — Picha, Camisea, Cashiriari, Timpia, Ticumpinia, Sensa, Yamariato, Mantalo — and, on the southern side, by the Manu and the upper Madre de Dios. The Pongo de Mainique, a narrow gorge on the Urubamba, is both an ecological threshold between Alto and Bajo Urubamba and a place of origin narratives. Two seasons govern life: heavy rain roughly November to April, when rivers rise and travel is hard, and lower water May to October, the season for good fishing, beach gardens and turtle eggs. Several protected areas overlap Matsigenka land. The Machiguenga Communal Reserve was created on 14 January 2003 by Supreme Decree 003-2003-AG, covering 218,905.63 hectares on the eastern flank of the Vilcabamba range; it is co-managed by the state protected-areas service SERNANP and by ECA Maeni, the executor of the administration contract, which represents fourteen indigenous communities, one rural settlement and three indigenous organisations. The adjoining Megantoni National Sanctuary protects the headwaters of the Timpia and Ticumpinia. Communities also live inside Manu National Park. To the north-west lies the Kugapakori, Nahua, Nanti and Others Territorial Reserve, first established in 1990 and raised to territorial reserve status in 2003, covering 443,887 hectares in La Convencion (Cusco) and Atalaya (Ucayali); Supreme Decree 001-2014-MC recognises Matsigenka groups known as Nanti and Kirineri, together with Nahua and others, as peoples in isolation or initial contact there. Matsigenka communities in Madre de Dios also border the Amarakaeri Communal Reserve.

Matsigenka belongs to the Arawak (Maipurean) family, within the group of closely related languages of the central Peruvian montane forest that also includes Ashaninka, Asheninka, Nomatsigenga and Kakinte. Its ISO code is mcb. The BDPI classifies it as vital — still learned by children in most communities — which sets it apart from the three other peoples in this group of profiles. Three regional varieties are recognised officially: Bajo Urubamba and Alto Urubamba, both in Cusco, and Manu, in Madre de Dios. Nanti, spoken by people living in the Kugapakori, Nahua, Nanti and Others Territorial Reserve, is treated in some classifications as a further Matsigenka variety and in others as a distinct language; the question is unsettled. A standard alphabet of 22 graphemes was approved by Ministerial Resolution 303-2015-MINEDU, and Matsigenka is used in intercultural bilingual schools across the Urubamba and Manu basins. Documentation runs from Dominican missionaries in the eighteenth and nineteenth centuries to the Summer Institute of Linguistics, present from the 1950s, which produced dictionaries, grammatical work and translations and also drove the consolidation of dispersed families into school-centred settlements. Speaker figures vary with the question asked: 6,629 people gave Matsigenka as their childhood language in the 2017 census, while some reference works cite up to 12,000 speakers. Transmission is strongest in the interior and weakest near roads, towns and the gas installations, where Spanish dominates schooling and wage work.

The Matsigenka household feeds itself from a swidden garden, the river and the forest. Manioc, sekatsi, is the staple, eaten boiled or roasted at nearly every meal and grown alongside plantains and bananas, maize, sweet potato, cocoyam, peanuts, beans, sugar cane, cotton, achiote and barbasco. The defining drink is masato, mildly fermented manioc beer: women peel, boil and mash the tubers, set the mash to ferment in a trough or jar, and serve it in bowls. Masato is not a luxury but the medium of hospitality and of collective work — a garden is cleared or a house roofed because the host has beer to offer. Fish is now the main protein for most communities, taken with hook and line, cast and gill nets, spears, weirs and traps, and with plant stupefiants such as barbasco used in blocked side channels; the BDPI records eight distinct fishing techniques. Men hunt peccary, monkeys, curassow, agouti, paca and occasionally tapir, formerly with bow and arrow and now largely with shotguns; game has become scarce near roads and settlements. Meat and fish are smoked on a raised wooden rack over a slow fire. Gathering brings palm fruits, wild honey, larvae and turtle eggs in the dry season. Labour is divided but not rigidly: men fell and burn the garden, hunt, build houses and make bows, arrows and twine; women plant, weed, harvest and process manioc, brew masato, spin and weave cotton, make pottery and plait mats and sifters. Both fish. Cash comes from coffee, cacao and achiote, grown since the 1950s, from craft sales, small livestock, wage labour with gas contractors, and — under real pressure — from timber.

Matsigenka material culture is dominated by cotton weaving, and the cushma tunic is its central object and emblem. Around it sit a coherent set of crafts: plaited basketry, sleeping and sitting mats, sifters and strainers for manioc processing, carrying baskets and tumplines, string bags and netting, carved wooden stools, spindles, bows and arrows, and ornaments of seeds, beads, feathers and animal teeth. Design is largely geometric — stripes, zigzags, bands, lozenges — worked in the natural browns, creams and rust reds of native cotton and plant dyes rather than in bright commercial colour, though aniline threads are now used alongside. Body and face painting with achiote (annatto) red and huito black is worn over the cushma for feasts and visits. The best-known collective is the Asociacion de Mujeres Artesanas of the native community of Timpia, on the Bajo Urubamba in Cusco, which uses the name Eto Tsireri — a reference to a Matsigenka narrative in which a spider taught the women of the community to weave. Their work has been shown at Ruraq Maki, the Ministry of Culture's national fair of traditional arts, and at ExpoAmazonica, and the association has publicly sought to widen its commercial network beyond fair-season sales. Matsigenka artisans also took part in the ARTE NATIVA fairs between 2017 and 2019. In Madre de Dios, the Shipetiari community has worked with the organisation Xapiri Ground on documenting craft knowledge, including the revival of tambora drum making. Individual Matsigenka artists are not widely known outside Peru; the public profile of the work rests with community associations rather than named makers.

Fifty-seven Matsigenka localities are titled native communities under the 1974 Native Communities Law, out of 111 registered by the BDPI. Representation runs through COMARU, the Consejo Machiguenga del Rio Urubamba, which speaks for around thirty communities; CECONAMA, the Central de Comunidades Nativas Matsigenka; FENAMAD in Madre de Dios; and ECA Maeni, which co-manages the Machiguenga Communal Reserve. The defining external fact of the last four decades is hydrocarbons. Shell explored the Camisea field between 1983 and 1988 and again from 1996; Chevron and Phillips Petroleum followed; production from Lots 88 and 56 began in 2004, making Camisea Peru's largest energy project and placing wells, pipelines and a fractionation plant inside Matsigenka territory. An independent environmental and social review commissioned by COMARU and AIDESEP warned that contingency planning could not be assumed to prevent introduced disease reaching isolated populations — a warning grounded in precedent, since a large share of the Nahua population died of respiratory disease after contact around the 1980s exploration. Communities have reported repeated pipeline spills, contaminated water, reduced fish and game, and little local benefit. Three prior consultation processes have involved the Matsigenka, on hydrocarbon Lots 175 and 191 and on changes to the zoning of the Amarakaeri Communal Reserve. Other pressures are illegal logging, road building and colonisation. Matsigenka initiatives include community life plans — one community allied to the Machiguenga Communal Reserve produced what SERNANP described as Peru's first virtual life plan — co-management of protected areas through ECA Maeni, intercultural bilingual schooling, community surveillance of territory, and craft associations building independent income.

Cotton, ampei, is grown in the garden, picked, deseeded by hand, and spun by women on a drop spindle into a fine, even thread. Weaving is done on a backstrap loom staked to a house post, with the weaver's body providing the tension. The product is the cushma, called manchakintsi in Matsigenka: a long, narrow tunic sewn from woven panels and worn by men and women of every age. The neckline distinguishes them — a V-shaped opening for men, a straight horizontal slit for women — and the cloth is typically banded or striped lengthwise. Ethnographic accounts put roughly three months of a woman's intermittent labour into a single cushma, which explains its historic value in trade: a cushma was exchanged with highland and river traders for a machete, an axe, cans of gunpowder or a parrot. Colour comes from the natural browns and creams of native cotton varieties and from plant dyes, including bark dyes such as the one Matsigenka call tsotoroqui, plus achiote red and huito black-blue. Beyond the cushma, women weave carrying straps and tumplines, infant-carrying bands, belts and small bags; netted string bags and hammocks are also made, and palm fibre is used where cotton is scarce. Cushmas and bands are sold at Ruraq Maki in Lima, at ExpoAmazonica, and through community associations, most visibly the Eto Tsireri weavers of Timpia. Everyday wear has shifted to manufactured clothing in most communities, and the cushma is now worn most often for feasts, meetings and visits — but it has not lapsed, and weaving remains a living skill passed from mother to daughter.

Matsigenka pottery is women's work and is technically simple and efficient. Clay is dug from river banks and cut backs, cleaned of stones, and tempered — the ethnographic literature records cotton fibre being mixed into the paste, a temper choice that is unusual and worth noting. Vessels are built by coiling and thinned by hand, then dried thoroughly in the shade before firing. Firing is done in the open, in a bonfire of wood and bark, for roughly an hour. While the pot is still hot it is sealed with manioc water — the starchy liquid from processing yuca — which soaks into the surface and closes the pores, giving a partly waterproofed vessel without a glaze. The repertoire was domestic: cooking pots, larger jars and troughs for fermenting and serving masato, bowls, and flat griddles for toasting. The craft has contracted sharply. Aluminium and enamelled pots, plastic buckets and manufactured basins have displaced almost all everyday earthenware over the past two generations, and pottery is now made in far fewer households than weaving or basketry. Ceramics still appear among the goods Matsigenka artisan associations bring to Ruraq Maki and regional fairs, which shows the knowledge has not vanished, but the current record on who is producing, in which communities, and at what scale is thin. This is a section that contributors from Matsigenka communities are well placed to correct and expand.

Matsigenka music is domestic and participatory rather than professional. The best-documented instrument is the sonkarintsi, also given as isonkare, a panpipe of bound cane tubes — one description records five tubes — played by men. Transverse and duct flutes of cane and bone are also used, along with rattles, seed anklets and leg bands that mark the rhythm of dancing. The tambora is a double-headed drum with a hollowed trunk body; the heads were traditionally made from howler monkey and spider monkey skin, prized for a deep resonance. In the community of Shipetiari in Madre de Dios, drum making had almost ceased within living memory, surviving as elders' recollection, and has been the subject of a documentation and revival effort with the organisation Xapiri Ground. Singing is largely unaccompanied and often solitary — songs about work, animals, longing and travel, sung quietly while weaving, paddling or walking. Collective music belongs to the feast. At a masato party and above all at the annual Moon Festival, people put on their best cushmas and paint, men play panpipes and women sing together in lines, and dancing continues through the night. There is no significant commercial catalogue of Matsigenka music; what exists sits in ethnomusicological archives and in recordings made by researchers and community projects rather than in released albums. Transmission happens by imitation within the household, and the Shipetiari drum work is an explicit response to the fact that this chain had thinned to breaking point.

Matsigenka social and ceremonial life is strikingly informal compared with the elaborate festival cycles of the northern Amazon. Ethnographers have repeatedly noted the near-absence of formal ceremony: there is no birth ritual and no naming rite, the girls' puberty seclusion and hair-cutting once described has largely lapsed, and marriage is enacted rather than solemnised — the groom builds a house and clears a garden near his parents-in-law, the bride's father directs her to prepare manioc for him, and when she offers it to him they are married. Either can end it. What carries the social weight is the masato feast. Beer parties gather households from a scattered hamlet, and they are for dancing, singing, drinking, joking and the sharp verbal sparring that vents grievance in a society with no chiefs and no courts; disputes are handled by gossip, shaming and, in the last resort, by moving away. The principal annual celebration is the Moon Festival, associated with Kashiri, the Moon, who is credited in Matsigenka narrative with giving manioc to people. Cosmology describes a layered universe, commonly given as ten levels with the earth low in the stack, populated by Tasorintsi creator and transformer figures, harmful beings called kamagarini, and the saankariite — the pure or invisible ones, spirits of plants and animals, with whom shamans keep relations. Death was formerly followed by disposal of the body in the river and burning of the house so the soul would not linger; today burial is normal, with quiet mourning and a restricted diet of green plantains and rice for about two weeks. The Pongo de Mainique remains a place of origin narratives and is treated as significant ground.

Matsigenka plant knowledge is unusually well documented and unusually large: researchers have put the number of medicinal species in use at around three hundred, alongside a substantial group of psychoactive plants, many of which have not been identified botanically by outside scholars or characterised chemically. Knowledge is distributed rather than concentrated. Ordinary adults treat everyday complaints, and it is gendered — women hold the knowledge concerning fertility, childbirth and infant care, men that concerning hunting, snakebite and wounds. Above this sits the specialist. The seripigari takes his title from seri, tobacco: the name is usually glossed as the one intoxicated by tobacco, and tobacco, not ayahuasca, is the master plant of Matsigenka shamanism. Ayahuasca is called kamarampi, a word built from the root meaning to vomit plus ampi, medicine. The seripigari uses these plants to make contact with the saankariite, the spirits of plants and animals, and illness is understood as a relational and spiritual matter — a soul lost, taken or attacked — rather than a purely bodily one. Becoming a seripigari requires long apprenticeship to an established practitioner, dietary and behavioural restriction, and a transfer of shamanic capacity from master to novice described in the ethnographic literature. Alongside this, state services operate health posts and itinerant brigades, and the Ministry of Culture has strengthened intercultural health provision for peoples in initial contact in the Kugapakori, Nahua, Nanti and Others Territorial Reserve, where introduced respiratory disease is a lethal risk. Biopiracy is a documented, ongoing harm rather than an abstraction: Peru's Comision Nacional contra la Biopirateria, chaired by INDECOPI, had identified 246 patent cases over Peruvian biological resources by 2022 — 66 involving sangre de grado, 39 maca, 27 marañon, and 10 each for camu camu and achiote — with most filings in China, the United States and Japan. No preparation methods, plant parts, doses or plant-and-method combinations are published here. That detail is the communities' intellectual property, and withholding it is also a safety line.

The Matsigenka house is called pankotsi. The older form recorded in the ethnography is a low oval building framed on heavy hardwood posts lashed with bark strips, walled in split palm wood, and roofed with thatch of palm leaf woven into panels — the roof sweeping down close to the ground so that wall and roof are almost continuous. A separate open-sided shelter alongside serves for cooking, manioc processing and sitting out of the sun; a raised rack for smoking meat and fish stands nearby. Floors were traditionally beaten earth, and a household of seven or eight people was typical. The ground around the house is kept swept clear of vegetation, which is explained as a defence against snakes and rodents as much as a matter of order. Newer houses are larger and rectangular, often raised on posts with a split-palm or plank floor, gabled rather than domed, with sawn timber and corrugated metal appearing where river or road transport allows. Settlement layout has changed more than the buildings. Matsigenka households were historically dispersed — single houses or small clusters of kin scattered along a stream, often hours apart, which suited a subsistence system that needed room and suited a social order with no chiefs. From the 1950s missions and the Summer Institute of Linguistics drew families together around schools, and the 1974 Native Communities Law made nucleation the condition of holding title. The resulting village is a cleared rectangle with houses around a central open space, a school, a health post and a football field, and a growing settlement pressure on nearby game and fish that the dispersed pattern never produced.
