Diffusionism: British Heliolithic, German Kulturkreis and American Culture Area Schools

6 Anthropological theories: (b) Diffusionism (British, German and American).

Official Syllabus: Paper I, Unit 6 (diffusionism)

1. What Diffusionism Was

Example first. In 1937 the American anthropologist Ralph Linton wrote a sketch, “One Hundred Per Cent American”, of an ordinary American’s morning. He wakes in a bed of a type first made in the Near East, wears pyjamas from India, uses soap invented by the ancient Gauls, drinks coffee from Abyssinia, and reads a newspaper printed in letters invented by ancient Semites on paper invented in China. At the end he thanks God, in an Indo-European language, that he is “one hundred per cent American”. The joke makes the diffusionist point: most of any culture is borrowed.

1.1 Diffusion, migration and diffusionism

• Diffusion is the spread of a culture trait (a tool, idea, custom or word) from the society where it began to other societies, through trade, war, intermarriage, travel or imitation.
• Migration is the movement of the people themselves, who carry their culture with them and adapt it to the new setting. Diffusion moves traits; migration moves their carriers.
• Diffusionism is the theory that diffusion and migration, not independent invention, explain most cultural similarities and change. It flourished from about 1890 to 1930.
• The core premise: humans are basically uninventive. Important inventions were made once, or a few times, at particular places and then spread. This directly denies the evolutionists’ psychic unity of mankind.

1.2 Diffusionism against evolutionism

The classical evolutionists (Tylor, Morgan, Frazer; Unit 6a) held that all societies pass through the same stages because all human minds work alike, so similar customs arise independently. They knew that borrowing happened, but treated it as secondary. Diffusionism reversed the emphasis. The table compares the two as explanations of culture change.

Basis	Evolutionism	Diffusionism
Source of similarity	Independent invention by similar minds	Borrowing or migration from a common centre
View of human mind	Inventive; psychic unity	Uninventive; imitative
Direction of explanation	Time: stages from simple to complex	Space: routes from centres to peripheries
Key question	“Which stage does this trait show?”	“Where did this trait come from?”
Pattern of change	Gradual, internal, one ladder	Sudden, external, by contact
Method	World-wide comparison of customs	Mapping distributions of traits
Weakness	Ignores contact and history	Ignores invention and why traits are accepted

The two are mirror images: evolutionism explains culture by time (stages), diffusionism by space (routes). Neither asks how a culture works now, which is why functionalism (Units 6d, 6e) rejected both.

1.3 How diffusion works

The diffusionist literature summarised several conditions of diffusion:

• A trait is adopted only if it is meaningful and useful to the receiving group, economically or socially.
• A trait is modified as it spreads, to fit new environments and customs.
• Diffusion brings culture change in the receiving group, sometimes slight, sometimes far-reaching.
• Barriers slow it: distance, isolation, poor communication and ethnocentrism (the belief that one’s own ways are best).
• The older texts claim that diffusion always runs from “higher” to “lower” cultures. This is not true: maize, potato, tobacco and rubber spread from the indigenous Americas to Europe, and the Hindu-Arabic numerals reached Europe from India through the Arab world.

Kinds of diffusion.

• Direct (neighbours borrow through daily contact), indirect (through intermediate peoples) and forced (imposed by conquest or colonial rule) diffusion.
• Stimulus diffusion (A.L. Kroeber, 1940): not the trait but the idea of it spreads, and the receivers invent their own version. The classic case is Sequoyah, a Cherokee who, knowing only that English speakers could write, invented a Cherokee syllabary (about 1821) unlike the English alphabet.

2. The British School: Pan-Egyptian or Heliolithic Diffusionism

Example first. Grafton Elliot Smith, an Australian-born anatomist, spent 1900–1909 as professor of anatomy in Cairo, studying mummies. He was struck by the likeness between Egyptian stone monuments and the megaliths (large standing stones and stone tombs) of Britain, the pyramids of Mexico, the pagodas of Asia and the mounds of North America, and concluded that the “rude” builders of Britain must have copied Egypt. From this grew the most extreme theory in the history of anthropology.

2.1 Grafton Elliot Smith (1871–1937)

• Works: The Ancient Egyptians and the Origin of Civilization (1911); The Migrations of Early Culture (1915); Human History (1930); The Diffusion of Culture (1933).
• The heliolithic culture. Smith used the term heliolithic (Greek helios, sun, and lithos, stone), borrowed from a colleague, for a culture complex that combined megalith-building and sun-worship with mummification, serpent-worship, tattooing, ear-piercing, circumcision, the couvade (the father’s ritual lying-in at childbirth), massage, the swastika symbol and divine kingship.
• The argument. In 1915 he wrote that this complex had come together in Egypt “nearly thirty centuries ago” and spread along coastlines across the world. Because the traits were found together along one route, he held that they must have travelled together.
• Natural man and the premise. Peoples untouched by Egypt lived as “natural man”, without agriculture, religion or the state. Man is essentially uninventive; civilization arose once, under the special conditions of the Nile, where irrigation led to the plough, writing, the state and sun-worship.

2.2 W.J. Perry (1887–1949)

• Works: The Megalithic Culture of Indonesia (1918); The Children of the Sun (1923); The Growth of Civilization (1924).
• Perry, a schoolmaster who became a lecturer at Manchester and later at University College London, gave Smith’s theory its motive. The “Children of the Sun”, rulers claiming descent from the sun-god, sailed out from Egypt in search of “givers of life”: gold, pearls, precious stones and amber believed to prolong life. Wherever they found these, they set up colonies, built megaliths and taught agriculture.
• Perry mapped megaliths and sources of gold and pearls across Indonesia and the Pacific and claimed that they coincided.

2.3 W.H.R. Rivers (1864–1922)

William Halse Rivers Rivers, a British physician and psychologist, came to diffusion from fieldwork, which makes him the most serious of the three.

• Before diffusion: member of the Torres Strait Expedition (1898); author of the genealogical method (1900), a technique of collecting kinship data through family trees; and of The Todas (1906), a study of the polyandrous Toda of the Nilgiri Hills.
• Conversion: in his presidential address to the anthropology section of the British Association at Portsmouth (1911), “The Ethnological Analysis of Culture“, Rivers announced that his Melanesian data could not be explained by independent evolution; they showed mixture of cultures brought by migrants.
• The History of Melanesian Society (1914): Melanesian culture was a blend of an older population and successive waves of immigrants. Small groups of immigrant men married local women, learned their wives’ language, yet kept certain customs, especially funeral rites. Rivers used this to explain why peoples alike in most respects differ in their burial customs.
• “The Disappearance of Useful Arts” (1912): some Melanesian islanders lacked canoes, pottery or the bow, although their ancestors must have arrived by canoe. Useful arts can be lost, so culture does not only progress. This challenged the evolutionist ladder from another side.
• Late phase: he moved close to Smith’s Egyptian scheme before his death in 1922.

2.4 Why the British school collapsed

• Form without function. Smith treated any vague likeness of form as proof of contact and ignored function and meaning: Egyptian pyramids were royal tombs, Mesoamerican pyramids were temple platforms, Asian pagodas are shrines, the Ohio mounds were burial mounds.
• Chronology. Radiocarbon dating destroyed the time sequence. The archaeologist Colin Renfrew, in Before Civilization (1973), showed that the megalithic tombs of western Europe are older than the Egyptian pyramids; the first phase of Stonehenge (about 3000 BCE) precedes the Great Pyramid (about 2560 BCE). Most South Indian megaliths date to the Iron Age (first millennium BCE), long after the pyramids, and served a local tradition of burial. Copies cannot be older than their supposed model.
• One centre only. The school ignored Mesopotamia, the Indus, China and Mesoamerica, independent centres of agriculture and cities.
• No fieldwork behind most claims, and contradictions: civilization began now in the search for the elixir of life, now in the lessons of the Nile flood.
• A racist echo. The idea that “natives” could not have built their own monuments survives in today’s pseudo-archaeology (§7.4).

The British school is often called the “last to appear and the first to disappear”: by the 1930s almost no professional anthropologist accepted it.

3. The German-Austrian School: Kulturkreis (Culture Circle)

Example first. In the 1890s the German geographer Friedrich Ratzel examined bows from West Africa and from Melanesia and New Guinea. The two regions are thousands of kilometres apart, yet the bows shared details that the purpose of a bow does not require: a similar flat cross-section of the shaft, the same way of fastening the string, the same feathering of the arrows. A bow needs a string; it does not need that particular knot. Ratzel concluded that such non-functional resemblances must come from a historical connection. This reasoning became the criterion of form, the foundation of the German-Austrian school.

3.1 The scholars

Scholar	Dates	Main works	Contribution
Friedrich Ratzel	1844–1904	Anthropogeographie (1882–91); Völkerkunde (1885–88), trans. The History of Mankind (1896–98)	Founder of anthropogeography; humans more imitative than inventive; criterion of form (Formgedanke) from the African bow (1891)
Leo Frobenius	1873–1938	“Der westafrikanische Kulturkreis” (1897–98); Paideuma (1921)	Coined Kulturkreis (culture circle); whole complexes travel, not single traits; a West African–Melanesian circle (masks, shields, drums, house forms); counted shared traits (“geographical statistics”); studied myth too
Fritz Graebner	1877–1934	“Kulturkreise und Kulturschichten in Ozeanien” (Berlin lecture 1904, published 1905); Methode der Ethnologie (1911)	Systematised the method; criteria of form and quantity; six culture strata in Oceania
Wilhelm Schmidt	1868–1954	Founded Anthropos (1906); Der Ursprung der Gottesidee (12 vols, 1912–55); Handbuch der Methode der kulturhistorischen Ethnologie (1937)	Catholic priest (Society of the Divine Word); led the Vienna school; four world circles; primitive monotheism

Against Adolf Bastian‘s “elementary ideas” (Unit 6a), Ratzel held that people are shaped more by one another than by climate or terrain, so the first task is to find where a trait came from and where it went. Frobenius widened the unit from single traits to whole complexes, and Graebner, with Bernhard Ankermann (who treated Africa), turned the idea into a world scheme.

3.2 The criteria of form and quantity

Graebner and Schmidt set out rules for deciding when two similar traits prove a historical connection. The two primary criteria are the heart of the school.

Criterion	Statement	Example
Form (quality)	A likeness that does not arise from the nature, material or purpose of the object points to a common origin, whatever the distance	The same string-fastening on West African and Melanesian bows
Quantity	The probability of a connection rises with the number of independent likenesses	Bows plus masks, shields, drums and house forms shared by the same two regions
Continuity (supporting)	A connection is stronger if the trait is found in intervening regions too	A chain of bow-types across the Indian Ocean coasts
Degree of relationship (supporting)	The closer the likeness, the closer the connection	Identical versus loosely similar designs

The logic is that of a detective. One shared clue may be chance; a dozen shared, non-functional clues are hard to explain without contact. The criterion of form screens out likenesses that any maker would arrive at (a bow must bend), and the criterion of quantity guards against coincidence. Schmidt’s Handbuch (1937) presented the two supporting criteria.

3.3 Graebner’s strata and Schmidt’s circles

Graebner’s six Oceanic strata, from oldest to youngest:

1. Tasmanian: simple food-gathering, the oldest layer.
2. Old Australian (boomerang): hunting with the boomerang.
3. Totemic: clans linked to animal and plant totems.
4. Two-class (moiety): society in two halves regulating marriage; horticulture.
5. Melanesian bow: the bow and related traits.
6. Polynesian: chiefs, gift-giving and redistribution, patrilineal descent.

Each layer was a Kulturkreis that had spread and settled over the earlier ones, like geological strata. Graebner also spoke of primary spread from a centre and secondary spread from the regions it first reached.

Schmidt’s four world circles (Kulturkreise):

1. Primitive (Urkulturen): food-gatherers such as the Central African forest peoples (then called Pygmies), the Fuegians of Tierra del Fuego and south-east Australians.
2. Primary: three independent developments: higher hunters (patrilineal, totemic), horticulturists (matrilineal) and pastoral nomads (patriarchal).
3. Secondary: mixtures of the primary circles.
4. Tertiary: the high civilizations of Asia, Europe and America.

Schmidt’s scheme looks like diffusion but reads as evolution: gatherers, then hunters, horticulturists and herders, then mixed societies, then civilizations, the familiar ladder in new clothes. In Der Ursprung der Gottesidee he argued that the oldest peoples believed in a single high god, so that primitive monotheism came first and later religions were degenerations. This reversed Tylor’s sequence of animism to monotheism (Unit 5a) and fitted Schmidt’s Catholic theology, which made critics suspicious of its neutrality.

3.4 The Vienna school and India

• Wilhelm Koppers, Schmidt’s student and head of the Vienna Institute of Ethnology, carried out fieldwork among the Bhil of Jhabua (central India) from October 1938 to December 1939, published as Die Bhil in Zentralindien (1948). Using language evidence, he argued that the Bhil descended mainly from a pre-Aryan hunting people who later adopted an Indo-Aryan language: a typical culture-historical reconstruction.
• Christoph von Fürer-Haimendorf, later the leading ethnographer of the Nagas, Konyaks, Reddis and Gonds, trained in Vienna under the culture-historical school. He chose the Naga Hills for his first fieldwork (1936–37) partly because the Vienna archaeologist Robert Heine-Geldern had linked their megaliths to South-East Asian culture complexes.

3.5 Assessment of the German-Austrian school

• Strengths. More cautious than the British school (several centres, not one); explicit criteria of proof; invention as well as diffusion; some fieldwork (Koppers, Gusinde, Haimendorf).
• Weaknesses.
  • No culture circle was ever established empirically; the circles were constructed from scattered traits.
  • Tracing world culture to four or five early bands and their migrations is speculation.
  • Similarity, even non-functional, does not always prove contact; independent convergence remains possible.
  • Museum methodology: traits classified out of context, as Boas complained in his 1911 review of Graebner’s Methode, where he called the procedure mechanical.
  • It described what spread and where, never why a trait was accepted, rejected or changed.
  • Its strata hid an evolutionary sequence and, in Schmidt, a theological aim.

4. The American School: Culture Areas and Age-Areas

Example first. On the Great Plains of North America in the nineteenth century, peoples as different in language as the Lakota, Cheyenne, Comanche and Crow shared a whole way of life: horse-mounted bison hunting, the portable tipi, the Sun Dance, military societies and painted hide robes. They spoke unrelated languages, so they had not inherited this way of life from one ancestor; they had borrowed it from one another within a region. The horse itself had arrived only after Spanish colonisation, yet spread across the Plains within a few generations. A culture area is the name for such a region.

4.1 From museum device to theory

• Otis T. Mason, curator at the US National Museum, grouped Native American peoples by “ethnic environments” in the 1890s to arrange museum displays.
• W.H. Holmes (1914) replaced “ethnic environment” with “culture area”: a region with an ethnic boundary, whose most typical tribes lie at its centre.
• Clark Wissler, curator at the American Museum of Natural History, in The American Indian (1917) mapped fifteen culture areas: ten in North America (including Mexico), four in South America and one in the Caribbean. He linked them to food areas: the bison area to the Plains, salmon to the North Pacific Coast, caribou to the sub-Arctic, maize to the agricultural Southwest and East, manioc to the Amazon.
• A.L. Kroeber, in Cultural and Natural Areas of Native North America (1939), regrouped North America into six grand areas with 84 sub-areas and matched them to natural regions.

4.2 The structure of a culture area

• Culture centre (Wissler): the zone where the traits typical of the area are most concentrated and most elaborated. Wissler held that it was also the oldest.
• Culture margin: the border zone, where traits of two or more areas mix.
• Culture climax (Kroeber): Kroeber preferred this term for the zone of richest development and greatest intensity, without assuming it was the point of origin.
• Age-area principle (Wissler, Man and Culture, 1923): traits spread outward from a centre in all directions, so a trait found over a wider area is older than one found over a smaller area. Of two traits, the one reaching the margins left the centre earlier. Edward Sapir‘s “Time Perspective in Aboriginal American Culture” (1916) set out similar rules for inferring time from distribution.
• Beyond America. Boas’s student Melville Herskovits identified an East African cattle area (1926), where cattle served as wealth, bride-price and ritual objects rather than mainly as food.

4.3 Criticism of the culture-area approach

• Static. The map shows a moment, usually the time of first European contact, not change.
• Boundaries are arbitrary; different traits give different boundaries.
• Material bias: areas were drawn mostly from food, tools and dwellings, less from belief and social organisation.
• The age-area principle is unreliable. Traits do not spread evenly in all directions or at a constant speed; mountains, seas and politics deflect them. A recent trait can spread faster and wider than an old one: Coca-Cola, invented in 1886, now covers far more of the world than many ancient crafts.
• Complex societies. The approach fits small tribal societies in contiguous regions but not stratified or urban societies, where traits spread by class and network rather than by territory.
• No “why”. Like the German school, it maps spread but does not explain why a trait is accepted, rejected or modified.

4.4 Boas and the American school

Franz Boas (Unit 6b) is often named as its leader because his historical method traced trait distributions in limited areas (the Tsimshian tales). Unlike the European schools, he required diffusion to be proved case by case, and stressed that receivers reinterpret what they borrow; hence the school’s other name, distributionist.

4.5 Culture areas in India

Indian anthropologists adapted the regional idea to Indian diversity:

• B.S. Guha, first Director of the Anthropological Survey of India, grouped tribes into north and north-eastern, central (middle) and southern zones.
• L.P. Vidyarthi divided tribal India into five regions: Himalayan, Middle India, Western India, South India and the Islands.
• Irawati Karve (Kinship Organisation in India, 1953) identified northern, central, southern and eastern kinship zones, each with its own marriage rules and kin terms (Unit 2.5b).

These are culture areas in method: regions of shared traits produced by shared history and contact.

5. The Three Schools Compared

The table sets the three schools side by side on the points on which they are usually compared.

Basis	British	German-Austrian	American
Other names	Pan-Egyptian, heliolithic, heliocentric	Kulturkreis, culture-historical, Vienna	Culture-area, distributionist, historical
Leaders	Elliot Smith, Perry, Rivers	Ratzel, Frobenius, Graebner, Schmidt	Wissler, Kroeber (Boas as method)
Number of centres	One (Egypt)	Several original circles	Many regional centres
Scale	World	World	Region (culture area)
Unit that spreads	A whole civilization complex	Culture complexes in waves	Single traits and complexes
Human inventiveness	Almost none	Limited; invention allowed	Ordinary; diffusion and invention both
Evolution	Rejected	Hidden in the strata	Rejected as unilinear
Method	Comparison of forms	Criteria of form and quantity	Mapping distributions; age-area
Fieldwork	Little (except Rivers)	Some (Koppers, Gusinde)	Extensive
Fate	Abandoned by the 1930s	Faded after 1950	Absorbed into acculturation studies

The trend runs from the extreme to the moderate: one world centre, then a few circles, then as many regional centres as the evidence showed. The more modest the claim, the better its evidence and the longer it survived; the culture area still organises regional ethnography, while the heliolithic theory survives only in pseudo-archaeology.

6. Critique of Diffusionism

• Humans are inventive. Agriculture, pottery, writing, cities and states arose independently in several regions (the Near East, China, Mesoamerica, the Andes). The premise of uninventiveness is false.
• Convergence and limited possibilities. Similar needs and materials can produce similar results without contact (Goldenweiser‘s principle of limited possibilities, 1913; Unit 6b).
• Form without meaning. Traits were compared as objects, stripped of their function and meaning in their own culture. A borrowed trait often changes its meaning: cricket, brought to the Trobriand Islands by missionaries, became a ritual contest between villages with war-dances and magic.
• No explanation of acceptance. Diffusion is selective. People borrow what fits their needs, values and structure, as the functionalists (Malinowski, Radcliffe-Brown) stressed; mapping routes does not explain this choice.
• Conjectural history. Most reconstructions were untestable inferences from distributions; Radcliffe-Brown dismissed them as “conjectural history”.
• Ethnocentric overtones and bad chronology. The claim that some peoples could only imitate echoed colonial ideas of “advanced” and “backward” races, and dating showed supposed copies to be older than their models (§2.4).

Was diffusionism an extremist view? The British school was: one centre, uninventive humanity, form taken as proof. The German-Austrian school was extreme in scale but disciplined in method; the American school was moderate. The lasting lesson is Boas’s middle position: cultures change by both invention and borrowing, and the weight of each must be shown case by case.

7. Legacy: Acculturation, Modern Diffusion and Globalisation

7.1 Acculturation

From the 1930s, American anthropologists shifted from traits spreading over centuries to cultures meeting now. Robert Redfield, Ralph Linton and Melville Herskovits, in their 1936 memorandum for the Social Science Research Council, defined it:

“Acculturation comprehends those phenomena which result when groups of individuals having different cultures come into continuous first-hand contact, with subsequent changes in the original culture patterns of either or both groups.”

The table separates the related terms.

Term	What spreads or changes	Contact	Example
Diffusion	Single traits	Direct or indirect; may be intermittent	Tobacco spreading from the Americas
Acculturation	Whole culture patterns of one or both groups	Continuous, first-hand	Tribal communities adopting market farming, schooling and a regional language
Assimilation	Minority absorbed into the dominant group	Prolonged, unequal	Loss of a separate language and identity
Enculturation	Culture learned by a child within its own society	Within the group	A child learning kinship etiquette

Kroeber connected the first two: diffusion concerns the elements of a culture, acculturation the whole culture; acculturation always involves diffusion. The memorandum named three outcomes: acceptance (traits replace older ones), adaptation (old and new blend into a new whole, which Herskovits called syncretism) and reaction (rejection).

• Contra-acculturation and nativism. When contact is forced, groups may reassert their old ways. Linton’s “Nativistic Movements” (1943) classified such efforts to revive or perpetuate selected traits. In India, the Birsa Munda movement (1895–1900) among the Munda combined religious reform with resistance to land loss and colonial rule.
• India. D.N. Majumdar‘s A Tribe in Transition (1937) studied contact among the Ho of Singhbhum; N.K. Bose‘s “The Hindu Method of Tribal Absorption” (1941) showed tribes entering the caste order. Srinivas‘s Sanskritization (1952) and Marriott‘s universalization and parochialization (Kishan Garhi, 1955) trace the two-way flow between great and little traditions: diffusion inside one civilization.

7.2 Diffusion of innovations

The sociologist Everett Rogers, in Diffusion of Innovations (1962), made diffusion measurable. Adoption follows an S-shaped curve: innovators (about 2.5 per cent) and early adopters (13.5) lead, the early and late majority (34 each) follow, laggards (16) come last. Adoption depends on advantage, compatibility with existing values, simplicity, trialability and visibility; compatibility restates the old rule that a trait spreads only if it is meaningful and useful to the receivers. The model guided agricultural extension and health programmes, including in India.

7.3 Globalisation

Globalisation is diffusion at unprecedented speed and scale, carried by trade, migration and media. Anthropologists describe three possible outcomes:

• Homogenisation: one culture (often American) spreads and erases others, as in talk of “McDonaldization”.
• Hybridisation (creolisation): borrowed elements mix with local ones into new forms (Ulf Hannerz). The anthropologist James Watson‘s Golden Arches East (1997) showed East Asian customers turning McDonald’s into a local social space. McDonald’s in India serves no beef and built its menu around local tastes such as the McAloo Tikki: glocalisation (the sociologist Roland Robertson‘s term for global forms adapted to local settings).
• Disjunctive flows: Arjun Appadurai (Modernity at Large, 1996) described five overlapping “scapes”: ethnoscapes (people), mediascapes (images), technoscapes (technology), financescapes (capital) and ideoscapes (ideas). They move independently, so cultures are reshaped unevenly rather than simply copied.

For tribal India, globalisation brings markets, mining and migration into indigenous economies (Unit 3b), a modern form of culture contact.

7.4 Migration or diffusion? The question returns

• Ancient DNA now tests what diffusionists could only guess: whether a trait spread by moving people (demic diffusion) or by moving ideas (cultural diffusion). The Rakhigarhi genome (Vasant Shinde and colleagues, Cell, 2019) from the Indus Civilization showed no Steppe-pastoralist ancestry and an Iranian-related ancestry that split off before farming began in Iran. The authors concluded that farming in South Asia did not require a large migration of western farmers: local hunter-gatherers took up farming, a case of diffusion of ideas, or independent development, rather than migration.
• Hyperdiffusionism today. The Society for American Archaeology wrote to Netflix on 30 November 2022 about the series Ancient Apocalypse, which attributed ancient monuments to a lost advanced civilisation; the letter said such theories rob Indigenous peoples of credit for their own heritage, the same flaw as Elliot Smith’s “natural man”.

Contemporary Developments

• Ancient DNA and the Indus Civilization (2019): the Rakhigarhi genome showed that farming in South Asia did not need a large migration of western farmers, turning the old “migration or diffusion” debate into a testable question.
• Pushback against hyperdiffusion (2022): the Society for American Archaeology‘s letter of 30 November 2022 to Netflix criticised Ancient Apocalypse for denying Indigenous peoples credit for their monuments.
• Repatriation and the end of the trait museum: new US NAGPRA regulations (2024) require consultation before displaying Native American cultural items, completing the move away from the trait-by-type museum displays from which culture-area studies grew.
• Glocalisation in India: global food and media brands adapt to local diets, languages and festivals: acceptance, adaptation and reaction in present-day contact.
