Kedayan

The Kedayan (also known as Kadayan) are an ethnic group of , primarily inhabiting and adjacent areas in the Malaysian states of and , where they speak a Malayic dialect closely related to and practice as agriculturalists. In , they are classified among the seven groups of the under the Nationality of , qualifying for privileges, and are noted as one of the largest such populations alongside the s. Their language, spoken by approximately 30,000 people in according to the Language and Literature Bureau, maintains vitality in family domains despite pressures from dominant varieties. Historically, the Kedayan adopted during the Sultanate's Islamic era, integrating cultural influences while retaining unique customs, including traditional wedding rites and folk medicine involving beliefs in unseen spirits. Origins are uncertain, with scholarly theories positing either development from Dayak subgroups or migration from accompanying the fifth , , in the . Despite linguistic and religious affinities with s, Bruneians recognize Kedayans as culturally distinct, reflecting their role in Borneo's pre-colonial and sultanate-era history without into the broader .

Origins and Etymology

Etymology of the Term

The term "Kedayan," along with variants such as "Kadayan" and "Kadaian," derives from Malayic linguistic roots denoting an "," "follower," or "slave," as defined in the Kamus Dewan dictionary, reflecting the group's historical role as attendants or servants to nobility in the Sultanate during its feudal era. This etymology aligns with oral traditions and poems like Syair Awang Semaun, which describe Kedayans as subordinates provided to sultans, such as those allegedly surrendered by Javanese figures to early Brunei rulers. The name functions primarily as an exonym imposed by neighboring and Dayak groups, rather than a self-applied endonym; ethnographic studies note that Kedayans traditionally identify as Urang Darat ("people of the land"), a term rarely used today in favor of the widespread "Kedayan" label across . Historical references to the term appear in sultanate traditions from the onward, such as during Sultan Bolkiah's reign (1485–1524), and in colonial-era ethnographies, including Allen R. Maxwell's 1980 study of Labu Valley communities, which underscores the exonym's adoption without altering core self-identification. No comprehensive linguistic analysis confirms alternative derivations, such as from toponyms or market-related terms like "kedai," despite occasional speculative links in non-academic discourse.

Theories of Origin

One theory attributes Kedayan origins to Javanese migrants recruited during the reign of Sultan Bolkiah (1485–1524), who reportedly admired rice-farming expertise encountered on and transported laborers to to disseminate wet-rice techniques. Oral accounts preserved in Bruneian describe these settlers as the forebears of the Kedayan, explaining their agricultural specialization and into local Malayic societies through intermarriage and cultural . However, this migration narrative remains unsupported by archaeological evidence, as excavations in Kedayan-inhabited regions of Brunei and Sarawak reveal no artifacts or settlement patterns indicative of a 15th–16th century Javanese influx distinct from broader Austronesian exchanges. Genetic analyses of Bornean populations, including Kedayan samples, detect no elevated Javanese-specific haplogroups or autosomal markers; instead, they show typical admixture profiles from ancient proto-Austronesian expansions, with Y-chromosome and mtDNA lineages aligning more closely to regional continuity than recent Java-derived gene flow. Linguistic evidence favors an Bornean origin, classifying Kedayan as a of the Malayic subgroup within Austronesian languages, with phonological and lexical features tracing to proto-Malayic speakers who diverged in approximately 3,000–4,000 years ago. Quantitative surveys of Kedayan speech patterns demonstrate syntactic and vocabulary retention from early Bornean Malayic substrates, without Javanese loanwords or innovations beyond those shared across insular Southeast Asian contact zones. This continuity, corroborated by comparative , implies Kedayan through local differentiation among riverine farming communities, rather than wholesale external importation. Empirical prioritization of genetic and linguistic data over oral traditions rejects of exotic , as Bornean genomic studies consistently highlight in-situ and low recent rates among Malayic groups like the Kedayan, underscoring from prehistoric Austronesian amid Borneo's diverse ecologies.

History

Pre-Islamic and Early Settlement

Archaeological findings in northern and southwest reveal evidence of settled communities during the , commencing around the 7th century AD, when iron tools facilitated forest clearance and the expansion of into interior riverine zones. These proto-historic patterns align with the inferred origins of Kedayan groups, who, as part of Borneo's Dayak ethnolinguistic continuum, established agricultural villages in such areas, focusing on wet-rice cultivation suited to alluvial floodplains. Kedayan settlement patterns emphasized clustered inland hamlets with central housing surrounded by radiating padi fields, enabling communal labor and defense while exploiting fertile lowlands near rivers like the Baram and Tutong. Oral traditions and comparative suggest these communities interacted with pre-sultanate coastal trade networks via fluvial routes, exchanging forest products such as resins and for metal goods and ceramics, though direct archaeological attribution to Kedayan remains elusive due to the absence of distinct material markers. Societal formation relied on animistic worldviews comparable to those documented among neighboring Dayak subgroups, positing spirits inherent in and requiring rituals for in farming and affairs. Kinship structures were bilateral, tracing through both maternal and paternal lines to organize longhouse-based villages, with authority vested in elders and communal heads rather than centralized chiefs.

Islamization and Sultanate Era

![Flag of Brunei.svg.png][float-right] The Kedayan adopted during the Islamic era of the Sultanate, transitioning from indigenous practices to full integration within Brunei's Muslim society. This process aligned with the sultanate's establishment as an in the 14th to 16th centuries, where the royal house's conversion facilitated the among inland ethnic groups like the Kedayan. Positioned as inland subjects distinct from the coastal Barunay Malays, the Kedayan contributed significantly to the sultanate's agricultural base through rice farming and other rural pursuits, bolstering and . Their settlements in interior regions supported the sultanate's and against external threats, with implied roles in broader efforts during periods of territorial . Kedayan elites occupied important ritual positions, including as murabitto—Islamic teachers who reinforced religious observance and cohesion within the sultanate's hierarchical structure. These roles underscored their adaptation of Malay-Islamic while maintaining distinct cultural elements, aiding the sultanate's internal unity.

Colonial Period and Modern Developments

During the over , established in 1888 and formalized with a in 1906, the Kedayan largely preserved their agrarian centered on wet-rice in rural kampungs, with minimal direct administrative interference as the protectorate focused on fiscal reforms and suppressing rather than reshaping . The Kedayan's recognition as one of seven groups of the under the 1961 Brunei Nationality Act ensured their eligibility for citizenship upon independence, reflecting colonial-era classifications that distinguished them from the ruling Malays while affirming native status. In under the Brooke dynasty from 1841 to 1946, followed by British rule until 1963, the Kedayan, classified among local Malay-related groups alongside Melanau, maintained relative autonomy in their rice-farming villages, as the administration prioritized anti-headhunting campaigns, trade expansion, and taxation over wholesale land reconfiguration for agriculturalists like them. Similarly, in (), British policies from the late onward recognized native land rights through , enabling Kedayan communities in southwestern areas to form reserves that buffered against alienation for , though broader indigenous resistance to timber concessions emerged in the mid-20th century. Post-independence, Kedayan in Malaysian and integrated into bumiputera policies following the 1963 federation, securing in education, economic opportunities, and land allocations under Article 153 of the Constitution, which privileges natives of those states alongside s. In , after 1984 independence from , the Kedayan aligned with the absolute monarchy's Islamic Monarchy framework, proclaimed in 1984 to emphasize Islamic values, customs, and loyalty, fostering national unity amid oil-driven modernization without eroding their status. Recent 2020s initiatives, including documentation of traditional ecological calendars and rituals, counter urbanization pressures from infrastructure like the , preserving Kedayan practices such as pre-Islamic agricultural rites despite migration to urban centers.

Demographics and Geography

Population Estimates

Estimates of the Kedayan population total approximately 240,000 across , based on a 2007 assessment encompassing and parts of Malaysian . In , where the group forms the largest concentration, numbers range from 100,000 to 150,000, though official censuses frequently aggregate Kedayans with the broader category, resulting in underrepresentation as a distinct ethnic subgroup within the 67% demographic share of 's ~455,000 total as of 2024. Smaller Kedayan communities exist in Malaysia, with linguistic surveys estimating around 30,000 speakers in (primarily in districts like , Beaufort, Kuala Penyu, and ), 30,000 in (concentrated in , , and ), and 15,000 in ; an additional ~600 reside in . These figures reflect minority status and integration challenges, as Kedayan demographics in are sometimes conflated with other groups in aggregated statistics, while data from the 2020s underscores their limited scale relative to dominant ethnicities like Iban. The profiles the Malay-Kedayan cluster (noting overlap) at 608,000 globally, with 195,000 in and 407,000 in , predominantly Muslim (94%), though this broader classification may encompass non-Kedayan elements and inflate distinct Kedayan counts for evangelistic purposes. Overall growth appears subdued, attributable to into urban Malay-majority societies and intermarriage, with limited distinct ethnic tracking in national censuses contributing to data variability across sources.

Distribution in Brunei and Malaysia

The Kedayan are concentrated in 's Tutong and Belait districts, where they maintain traditional settlements in rural, river-adjacent villages amid oil and gas production zones. These areas, part of 's western , support their agrarian lifestyles near the Tutong and Belait rivers, which facilitate access to fertile floodplains. In 's state, Kedayan communities cluster in the southwestern districts of Beaufort, Kuala Penyu, , and , often in riverine villages along tributaries of the Padas and Pegalan rivers. Further north in , they inhabit the northern belt, including riverine locales in , , , Sibuti, and divisions, adapting to coastal and inland river systems bordering . Historically, Kedayan settlement patterns reflect adaptations to Borneo's and upland ecologies, with traditional dry (padi ladang) cultivation in shifting fields on hilly slopes and marginal lowlands driving semi-nomadic cycles tied to and seasonal floods. This swidden , suited to non-irrigated terrains unsuitable for permanent wet , encouraged dispersed, mobile villages rather than fixed agrarian hubs, contrasting with more sedentary coastal groups. In peat-influenced swamps near river deltas, such as those in southwestern , Kedayan practices incorporated selective clearing and rotation to mitigate waterlogging, preserving balance amid nutrient-poor soils. Recent decades have seen accelerated urban migration among Kedayan, drawn to economic hubs like in Brunei-Muara district and in for oil-related jobs, education, and services, reducing rural densities in core districts. Brunei's urban population share reached 77.6% by 2021, with indigenous groups including Kedayan contributing to this shift from agrarian bases. In , internal migration patterns since 2000 have funneled rural ethnic minorities toward coastal cities, altering traditional distributions while sustaining cultural ties through remittances and periodic returns.

Diaspora Communities

Kedayan diaspora populations outside Borneo remain small and transient, consisting mainly of individuals pursuing or skilled abroad rather than forming permanent settlements. Estimates indicate around 800 members of the related and Kedayan groups reside in the , often as temporary expatriates via student or work visas. Similar modest numbers exist in , reflecting patterns of migration from and northern since the late . These expatriates maintain homeland ties through financial s, which support family agricultural activities in rural Bornean villages, though specific Kedayan remittance volumes are undocumented amid broader Bruneian and Malaysian migrant flows. Cultural retention efforts include informal associations fostering language use and traditions, yet pressures in host countries—such as intermarriage and adoption of local norms—pose challenges to preserving distinct Kedayan identity, including and customary practices. No large-scale organized communities have emerged, distinguishing Kedayan patterns from more extensive or Iban diasporas.

Language

Classification and Dialect Features

The Kedayan belongs to the Malayic of the Malayo-Polynesian within the Austronesian family. It shares 83–89% with and 75–81% with Standard Malay, though some analyses estimate up to 94% overlap with Brunei Malay dialects, supporting its close affiliation despite challenges. Phonologically, Kedayan features a reduced vowel system of three monophthongs—/i/, /a/, and /u/—mirroring , alongside 17 consonants including stops, nasals, fricatives, and . A distinctive trait is the absence of the /r/ , realized as a flap or in related varieties like , which contributes to its archaic profile relative to coastal Malayic lects. The preserves archaisms, including specialized terms for inland and not prominent in urban or coastal varieties, reflecting the Kedayan's historical agrarian and forested . Kedayan lacks a standardized , with writing typically employing ad hoc adaptations or Jawi for limited religious or informal purposes, resulting in a sparse documented primarily derived from oral recordings and phonetic transcriptions rather than extensive literary works.

Usage, Vitality, and Influences

The Kedayan language exhibits robust intergenerational transmission within family domains, with surveys in Sarawak from 2021 indicating that speakers remain loyal to it as their primary medium of domestic communication. However, usage declines sharply outside the home, where Kedayan speakers frequently shift to Brunei Malay or Standard Malay for public interactions, interethnic exchanges, and formal settings, reflecting the lingua franca role of Malay varieties across Borneo. This pattern of domain-specific maintenance underscores adaptation to multilingual environments dominated by Malay and English pressures. Linguistic influences on Kedayan stem primarily from its close ties to , with exceeding 80%, alongside effects from Bornean languages like Dusun and Iban in shared multicultural contexts. is prevalent among speakers, particularly when interfacing with Brunei Malay in urban or cross-ethnic settings, facilitating communication in Brunei's and Sarawak's diverse communities. Vitality assessments rate Kedayan as definitely endangered, with a score of 2.0 on the in , signaling risks from , to dominant varieties, and limited institutional support. Despite family-level , broader threatens without targeted revitalization efforts amid ongoing .

Culture and Traditions

Social Structure and Customs

The Kedayan system is bilateral, or cognatic, with and reckoned through both paternal and maternal lines, enabling flexible recruitment of for and economic . This structure supports localized marriages to consolidate land holdings, as young couples often receive plots from parents following jungle clearance to establish rights. Kedayan villages feature dispersed, non-nucleated settlements of houses clustered near fields, governed by a ketua kampung or wakil ketua kampung who leads community decisions and adjudicates minor disputes via , the unwritten customary norms emphasizing consensus and restitution. Post-harvest feasts known as makan tahun reinforce bilateral kin ties, gathering relatives for communal meals that vary in scale by locality, such as multiple events in larger villages. Daily norms reflect gendered labor divisions integral to subsistence agriculture: men clear fields, plant rice by dibbling seeds, and collect forest resins like copal for trade, while women uproot wild tubers, process harvests, and engage in crafts such as weaving textiles for household use. Kin-based mutual aid underpins padi farming cycles, with families coordinating planting and reaping to sustain wet-rice systems reliant on rainfall and slash-and-burn techniques.

Traditional Medicine and Healing Practices

Kedayan traditional medicine centers on herbal remedies derived from local flora, administered by community healers referred to as orang pandai (skilled persons), who combine plant extracts with ritual prayers for treating physical and spiritual ailments. Ethnobotanical surveys in Brunei Darussalam, conducted between 2018 and 2020, document over 175 medicinal plant species from 85 families, with a focus on digestive disorders (67 species) and postpartum care. Common preparations include decoctions or poultices, such as pandingin (Bryophyllum pinnatum) leaves for reducing fever and mixtures of sambung (Blumea balsamifera), ringan-ringan (Flemingia strobilifera), and kuduk-kuduk (Melastoma malabathricum) for maternal recovery. Harvesting adheres to a traditional ecological calendar, prioritizing dawn collections to maximize potency and avoiding times like sunset prayers (maghrib) or calls to prayer (azaan), linking lunar tides and seasonal cues to treatment efficacy. These practices integrate Islamic principles, emphasizing natural causation over supernatural intervention, in alignment with prohibitions on (sihr) outlined in Quranic teachings. Healers employ dukun or bomoh-style methods but substitute invocations with verses from the for exorcisms, distinguishing benevolent from malevolent spirits while rejecting animistic rituals. For instance, bidara (Ziziphus mauritiana) leaves mixed with salt serve in protective rituals recited with Islamic prayers, reflecting post-15th-century adaptations following Kedayan . This holistic approach addresses imbalances in bodily humors and spiritual disturbances, such as keteguran (a trance-like state), which often overlooks. Despite widespread access to modern clinics in and Malaysian , traditional remedies persist, with approximately 70% of the population—including Kedayan communities—utilizing them for or complementary care, particularly in rural Kiudang areas. Knowledge transmission occurs vertically from elders to kin, favoring from accessible disturbed habitats like roadsides over . While some documented exhibit bioactive compounds validated in regional pharmacological screens (e.g., effects in Blumea ), relies on empirical observation rather than controlled trials, leading to critiques that spiritual elements may delay pharmaceutical intervention for acute conditions. Persistence reflects cultural trust in localized, low-cost options amid hybrid healthcare use, though healers' cited remedies align more closely with historical records than non-specialists'.

Festivals and Life Cycle Events

The Kedayan observe Makan Tahun, an annual marking gratitude for the yield, typically held in late year following the culmination of the . This three-day communal event features traditional foods such as kelupis ( steamed in leaves), cultural performances, and activities that preserve ethnic heritage while fostering unity among participants. Celebrations occur in locations like in and Siandang Beach in , often incorporating modern elements like food festivals to boost local economy without altering core rites. Kedayan weddings follow Islamic marriage (akad nikah) protocols but incorporate customs, including the njaum-njaum proposal where the groom's family formally requests the bride's hand through intermediaries and symbolic gifts. The bertimbang or bersanding ceremony, held at the bride's home, seats the couple on a decorated as symbolic royalty, with the groom's procession undergoing malliwan rituals of entry and homage. Post-ceremony seclusion lasts 40 days to ward off misfortune, blending pre-Islamic protective practices with Sharia-compliant unions. Birth and circumcision rites align with Sunni Islamic observances, such as aqiqah (animal sacrifice on the seventh day) for newborns, though specific Kedayan variations remain undocumented in available ethnographies. Funerals adhere strictly to Sharia mandates for prompt burial within 24 hours, with communal prayers (solat jenazah) and washing of the deceased by same-sex relatives, reflecting the community's full integration of Islamic law over animistic extensions.

Religion

Conversion to Islam

The Kedayan, indigenous to and initially practitioners of animistic folk religions with subsequent influences from and , transitioned to gradually during the late , coinciding with the reign of Sultan Bolkiah (r. 1485–1524) in the Sultanate. This shift was propelled by the sultanate's expansion, maritime trade networks introducing Muslim merchants from Arabia, , and , and royal edicts mandating adherence among subjects, including tribal groups like the Kedayan. Early evidence of institutionalization includes the establishment of mosques in during this period, such as foundational structures under Bolkiah's rule that symbolized the faith's entrenchment among newly converted communities. Sufi traditions, dominant in the initial Islamization of Borneo and Southeast Asia, facilitated the process by permitting accommodations between Islamic theology and local animism, interpreting indigenous spirits as akin to jinn or subordinate entities within a monotheistic framework. This syncretic approach, rather than coercive puritanism, enabled pragmatic adoption amid ongoing trade dependencies on Muslim networks, though royal decrees from the sultanate enforced broader compliance. Markers of residual pre-Islamic influences persist in empirical records of post-conversion practices, such as the retention of (shamanic healers, termed orang pandai among Kedayans) who blend Qur'anic recitations with invocations addressing unseen spirits and taboos rooted in . These healers treat ailments attributed to spiritual imbalances, evidencing incomplete doctrinal displacement despite formal , as documented in ethnographic accounts of Kedayan folk medicine. Such continuities reflect causal realities of cultural inertia, where sultanate-driven Islamization prioritized nominal allegiance over eradication of embedded rituals.

Syncretic Elements and Contemporary Observance

Among Kedayan , syncretic practices rooted in pre-Islamic animist traditions persist alongside Islamic observance, including rituals such as grave cleaning during the month of and hosting mourn feasts, which blend with religious commemoration. These elements reflect cultural inertia, driven by factors like and perceived , as evidenced by surveys showing high intentions to maintain such practices despite their incompatibility with orthodox Islamic teachings that emphasize and rejection of superstitious intermediaries. Consultations with , traditional shamans offering herbal and ritualistic healing, continue among some Kedayan despite Bruneian religious authorities deeming such practices deviant from , as they invoke causation over empirically verifiable medical approaches. This retention occurs amid fatwa-guided prohibitions on and , highlighting tensions between entrenched folk beliefs and calls for purification aligned with causal explanations in health and misfortune. Contemporary Kedayan adherence to Islam's five pillars—profession of faith, , almsgiving, , and —remains strong, particularly in urban where state-enforced since 2014 reinforces orthodoxy, yet rural communities exhibit greater tolerance for jimat (talismans) as protective charms, sustaining syncretic dualism. Salafist-influenced reforms, including Wahhabi ideological penetration via global networks, have intensified scrutiny of these holdovers, promoting a stricter that challenges Kedayan cultural practices as (innovation), though empirical studies indicate limited erosion due to localized social pressures.

Economy and Livelihood

Historical Occupations

The Kedayan traditionally relied on swidden agriculture, known locally as ladang, for subsistence rice cultivation, clearing forested hillsides to plant dry-land paddy varieties adapted to Borneo's inland terrain. This practice, documented among Kedayan communities in Brunei as early as the 1970s but rooted in pre-colonial settlement patterns, involved rotational burning of secondary forest to enrich soil fertility for hill rice (padi bukit), yielding staple crops sufficient for household needs amid the region's undulating topography and seasonal monsoons. Supplementary livelihoods included for wild edibles, small game with blowpipes and spears, and in rivers using poisons derived from local or simple traps, activities that complemented rice shortages during lean periods and reflected to Borneo's dense rainforests. These pursuits, integral to Kedayan economic resilience prior to 20th-century disruptions, provided proteins and supplementary starches without reliance on intensive systems unsuitable for upland interiors. Riverine networks facilitated trade of forest products such as and resins to coastal sultanates, with Kedayan acting as key suppliers of rice and jungle goods to Brunei's court from at least the onward, leveraging navigable waterways for exchanges that sustained pre-modern barter economies. This exchange, often conducted via dugout canoes on tributaries like the Belait River, underscored the Kedayan's role in regional provisioning without large-scale commercialization.

Modern Economic Roles

In Brunei, the discovery and exploitation of oil and gas reserves since the early 20th century, with significant economic expansion post-1970s, prompted Kedayan communities to diversify from into wage labor tied to the sector and related services. This shift included roles in , , and support industries, alongside increased participation in the expansive , which absorbs a substantial portion of Brunei's due to state-driven policies favoring groups like the Kedayan. In Malaysian , particularly , Kedayan have transitioned toward commercial agriculture, notably oil palm cultivation, amid the industry's rapid growth from the onward, which covers over 1.5 million hectares in the state by 2015. Smallholder involvement provides supplementary income, but communities face vulnerabilities from native customary rights (NCR) disputes, as seen in Bekenu and where lands totaling over 1,700 hectares were leased for plantations since 2001, sparking legal challenges over alleged encroachments despite official denials of mass evictions. Such conflicts, often involving provisional leases excluding NCR zones yet leading to court cases by 2008, expose Kedayan to risks of lost access to traditional farmlands and potential economic .

Identity and Relations

Distinction from Brunei Malays

The Kedayan maintain a distinct ethnic identity from the Malays despite sharing the Malayic language family, as the predominant religion, and historical ties within Bornean societies. Colonial-era observations and ethnographic accounts classified Kedayan as inland agriculturalists specializing in padi (wet rice) farming and sago processing, contrasting with the coastal trading, , and maritime orientations of Brunei Malays. This geographic and occupational divide—Kedayan predominantly in riverine interiors versus Brunei Malays along shorelines—reinforced separate social roles, with Kedayan often serving as intermediaries in land-based economies while Brunei Malays dominated sultanate-linked commerce. Linguistic nuances further delineate boundaries: the Kedayan dialect features unique phonological and lexical elements, such as retained archaic forms not prevalent in standard , serving as a core identity marker amid broader . Kedayan communities exhibit preferences for , prioritizing intra-group marriages to preserve customs like specific rice-planting rituals and kinship structures, which differ from Brunei Malay practices influenced by courtly hierarchies. Self-identification remains robust, with Kedayan rejecting subsumption into the pan-Malay category; surveys and censuses in consistently record them as a separate puak (), even as official Brunei policies group them under "indigenous Malays" for nationality purposes since the 1961 Brunei Nationality Act. In policy contexts, these distinctions manifest in , where Kedayan hold bumiputera () status entitling them to in and land rights, akin to other Borneo natives, but in , their smaller population (estimated under 10,000 as of recent ethnolinguistic profiles) positions them secondary to dominant groups like the in native land claims and political representation. This reflects pragmatic ethnic hierarchies in Sabah's federal framework, where Kedayan leverage shared Muslim identity for alliances yet assert autonomy to avoid dilution in broader categorizations.

Interactions with Other Borneo Ethnic Groups

Kedayan communities, primarily lowland agrarian groups under Brunei sultanate influence, historically maintained symbiotic trade relations with upland ethnic groups like the Dusun and Iban, exchanging , , and coastal goods for forest products such as resins, , and mediated by sultanate officials. These exchanges supported Kedayan while integrating tribal produce into broader regional networks, though sultanate oversight often extracted tributes, reinforcing hierarchical dependencies. Alliances formed through kinship ties, honorary titles, and shared Islamic conversion ("masok Melayu") bound some Kedayan-aligned polities with Dayak subgroups, including Iban, against external threats, including early colonial pressures in the when Brunei leveraged tribal loyalties to resist European encroachments. However, inter-group frictions persisted, with sultanates employing divide-and-rule strategies to pit Iban raiders against rival tribes, occasionally drawing Kedayan into defensive coalitions or resource disputes over river access and livestock. In , where Kedayan populations are smaller and interspersed with Iban and other Dayak, territorial tensions over arable land and hunting grounds have historically been mediated through , emphasizing negotiation and compensation to avert escalation into broader conflict. Such resolutions preserved relative peace amid resource competition, though enforcement relied on local rather than centralized authority. Contemporary urbanization in Borneo has fostered multiculturalism, promoting interethnic intermarriages between Kedayan and groups like Iban, Dusun, and , which blend traditions but contribute to the erosion of distinct Kedayan practices like specific rituals. In and Malaysian cities, these unions, often facilitated by shared Islamic observance, enhance but prompt debates on identity preservation among Kedayan elders.

Notable Kedayan

In Brunei

Kedayan in , recognized as part of the indigenous race under the Brunei Nationality Act of 1961, are integrated into the sultanate's governance structure, often serving in local administrative roles such as village heads (ketua kampung) in Kedayan-populated areas like Ampar Tenang or Sungai Kedayan, where they uphold loyalty to Sultan Hassanal Bolkiah and promote Islamic values in community affairs. This reflects their historical pivotal position in traditional society, contributing to agricultural and rural stability while aligning with the absolute 's emphasis on Islamic (MIB). Distinct ethnic identification in national or remains rare, as Kedayan are constitutionally subsumed under the category, facilitating seamless participation without separate prominence.

In Sabah and Labuan

Dr. Yusof Yacob, a Kedayan from , holds the position of state assemblyman for the Sindumin constituency (N35) in the , representing areas with significant Kedayan populations such as . As president of Persatuan Kadayan Sabah (PAADIAN), he leads efforts to preserve Kedayan language, traditions, and identity, including discussions on the ethnic group's origins and distinctions from other subgroups. Yacob was re-elected to the PAADIAN presidency for the 2024–2026 term, emphasizing cultural documentation amid 's diverse indigenous landscape. In politics, Yacob serves as head of the Gagasan Rakyat (GRS) branch for Sindumin and chairs Qhazanah Berhad, a state investment entity, integrating Kedayan interests into 's governance under Malaysia's federal system. His roles reflect adaptations to multi-ethnic coalitions, such as GRS alliances, while advocating for native rights in state assemblies. Kedayans in , part of the with historical ties to , maintain community ties but lack prominent political figures at the state level, often aligning with broader representation in federal matters.

In Sarawak

Haji Abdul Gapor served as a pivotal community leader among the Kedayan in early 20th-century , appointed as Penghulu Kaum Kedayan by the Brooke administration, which facilitated the migration of Kedayan families from to the Sibuti district around , establishing a significant settlement there. This relocation bolstered the Kedayan presence in northern amid the White Rajah's efforts to administer ethnic groups, though Kedayan communities remained marginal compared to dominant Dayak populations like the Iban, who held greater influence in bumiputera political structures. In contemporary Sarawak, Kedayan leaders focus on cultural preservation and community advocacy within a landscape where Dayak-majority hierarchies often prioritize Iban and interests in resource allocation and representation. Mohamad Abdullah Jamin, vice president of Sarawak Kedayan and chairman of Persatuan Kedayan , has organized events promoting unity, such as prayers for community members and pledges of support for local governance, while emphasizing cultural traditions like distribution during to foster social cohesion. These efforts highlight Kedayan for minority visibility, though achievements remain constrained by the ethnic group's smaller demographic footprint in Sarawak's multi-tiered .

In the Diaspora

The Kedayan diaspora remains small and transient, with limited permanent settlements outside due to strong economic incentives to remain in and Malaysian states. An estimated 800 individuals identifying as or Kedayan reside , primarily as students on college campuses or temporary businessmen. These numbers reflect broader patterns of short-term for or professional opportunities rather than community formation, given Brunei's robust economy and low incentives for relocation. No dedicated Kedayan cultural associations or organized heritage preservation efforts are documented abroad, though expatriates likely maintain traditions informally through family networks, language use (primarily dialects), and religious practices, with 99% adhering to . This aligns with the group's agrarian and community-oriented roots, which prioritize return over institution-building. Evidence of larger or more structured overseas communities is absent from available demographic .
