A comprehensive scholarly study of the trans-border Western Yorùbá subgroups in the Republic of Benin and the Togolese Republic, examining their historical kingdoms, dialectology, dynastic origins, religious institutions, and cross-border political evolution.
The trans-border Western Yorùbá subgroups constitute a network of historically autonomous, Yorùbá-speaking communities inhabiting the central and southern regions of the contemporary Republic of Benin and the Togolese Republic, with direct historical and cultural continuities extending across the international border into southwestern Nigeria . Geographically bounded by the Wémẹ̀ (Ouémé) and Ọpárá river valleys to the east and the Mono and Ogou river basins to the west, these populations comprise major historic polities including Kétu, Ṣábẹ́ (Savè), Ìdàáṣà (Dassa-Zoumè), Iṣa (Bantè), Aná or Ifẹ̀-Togo (Atakpamé), the northern outlier of Mokolé (Kandi), and various Southern Nàgó chiefdoms .
Historically designated collectively as Nàgó (or Anagó) in Dahomean, Togolese, and Francophone records, these groups developed distinct monarchical systems tracing dynastic origins to Ilé-Ifẹ̀ and Old Ọ̀yọ́, while maintaining political sovereignty outside the direct administrative centralization of the eastern metropolitan empires . Throughout the eighteenth and nineteenth centuries, the Western Yorùbá occupied a precarious geopolitical frontier between the expanding militarized state of Dahomey to the west and the Ọ̀yọ́ Empire and later Ègbá polities to the east, enduring severe demographic displacement, siege warfare, and enslavement campaigns .
Following the European partition formalized by the Anglo-French Agreement of 10 August 1889, these communities were split across French colonial Dahomey, German Togoland (later French Togo), and British Nigeria, giving rise to distinct cross-border migration patterns, divergent administrative experiences, and bilingual social networks that continue to shape West African borderland identity today .

The Western Yorùbá do not form a single, uniform polity. They constitute a mosaic of distinct subgroups, each defined by localized geographic terrain, political traditions, and dialectal features . In Francophone ethnography and regional administrative discourse, the overarching term Nàgó (alternatively spelled Nagot or Anagó) has historically functioned as a general ethnonym for all Yorùbá-speaking populations in Dahomey and Togo, though localized populations prioritize specific subgroup identities .

The Kétu represent one of the oldest and most prestigious monarchical states of the Yorùbá world . Centered on the ancient walled city of Ilé-Kétu in the Plateau Department of Benin, Kétu territory historically stretched eastward across the modern international border into the Yewa (formerly Egbado) region of Ogun State, Nigeria . The traditional ruler, the Alákétu (etymologically derived from Alá-Kétu, "Owner/Lord of Kétu"), presides over a royal structure that oral tradition traces directly to the ancestral dispersals from Ilé-Ifẹ̀ under the legendary leader Ṣóipàsán . Kétu society is renowned for its elaborate fortifications, particularly the surviving historic town gate known as Àkàbà Ìdènà, and for being the historical epicenter of the Gẹ̀lẹ̀dẹ́ masquerade institution .
Located north of Kétu in the Collines Department of central Benin, the Ṣábẹ́ (frequently spelled Cabe or Savè) occupy the fertile savannas flanking the Ọpárá River . Ruled by the Oníṣábẹ of Ṣábẹ́, the kingdom was founded through the consolidation of autochthonous agricultural groups by dynastic migrants associated with the legendary figure Babagídàí . The territory of Ṣábẹ́ historically bordered Old Ọ̀yọ́ to the east and Borgu (Baatombu) populations to the north, creating a dynamic frontier zone characterized by bilingualism, cross-regional trade, and recurring military defense against Dahomean incursions .
The Ìdàáṣà inhabit the rocky inselberg landscapes of central Benin, centered around the city of Dassa-Zoumè, traditionally known as Igbó Ìdàáṣà . The territory is defined by forty-one sacred granitic hills (òkè) that historically provided impenetrable natural fortifications against invading Dahomean and Fon slave-raiding armies . The ruler of the Ìdàáṣà traces political lineage to a sovereign designated as the Jagun or Olófin, whose dynastic group integrated various pre-existing hunter-gatherer and priestly lineages . Ìdàáṣà is renowned as a primary historical sanctuary for the veneration of the ancient earth and maternal deity Nàná Bùkúù (Nana Buruku) .
The Iṣa occupy the western subdivisions of the Collines Department, with their administrative and cultural heartland located in the commune of Bantè and extending through Pira, Gouka, and Akpassi . Ethnographers and historical linguists suggest that the Iṣa represent one of the most archaic Yorùbá-speaking strata in central Benin, having occupied their settlements prior to the secondary dynastic migrations from Ọ̀yọ́ and Ifẹ̀ . Their territory forms a direct linguistic corridor connecting the central Beninese Yorùbá communities with the Ifẹ̀ populations of eastern Togo .
The westernmost historic Yorùbá population in West Africa is represented by the Aná and Ifẹ̀-Togo subgroups, settled primarily in the Ogou and Anié prefectures of the Plateaux Region of Togo, centered on the city of Atakpamé, with related settlements in the Doma and Tchetti districts along the Benin-Togo frontier . Surrounded by seven prominent hills, Atakpamé became a major defensive refuge during the seventeenth and eighteenth centuries for migrants moving westward from Ilé-Ifẹ̀, Ṣábẹ́, and the intermediate settlement of Ìjá-Òkú . The Ifẹ̀-Togo language (Èdè Ifẹ̀) preserves archaic grammatical and lexical features of Proto-Edekiri, demonstrating systematic phonological divergences from eastern Standard Yorùbá .
In the Donga Department of northwestern Benin and extending into the central border regions of Togo, there exists a pocket of northern Yorùbá communities known as the Northern Nàgó, Kura, or Manigri-Kambolé . Centered in towns such as Bassila, Manigri, and Kikélé in Benin, and Kambolé and Balanka in Togo, these communities developed at the strategic junction between Yorùboid, Gur, and Volta-Niger speech communities . Having absorbed significant northern cultural and Islamic influences through trade with the Hausa, Baatombu, and Dendi, they retain distinct monarchical structures and ancestral masquerade traditions .
The Mokolé (also transcribed Mokollé, Monkole, or Féri) represent the extreme northern frontier of Yorùboid settlement in West Africa, located in the Alibori Department around the town of Kandi, more than two hundred and seventy kilometers north of the contiguous Yorùbá cultural zone . Completely surrounded by Baatombu (Bariba) and Dendi populations, the Mokolé migrated from the Ọ̀yọ́ Empire during the sixteenth or seventeenth century, functioning historically as specialized hunters, cavalrymen, and ironworkers . While adopting various northern cultural practices and lexical loanwords, the Mokolé have preserved a distinct Yorùboid speech variety closely related to Ṣábẹ́ and Old Ọ̀yọ́ dialects .
Along the coastal and forest belt of southern Benin, spanning the Plateau and Ouémé departments, are the Southern Nàgó, the Ìjẹ̀, the Òhòrí (Ije/Ohori), and the Àjàṣẹ́ (Porto-Novo) populations . The Òhòrí inhabit the swampy, clay depression of the Gbòdògí forest around Pobè and Ketu, where they historically maintained fierce political independence against both Dahomean armies and French colonial tax collectors . The Àjàṣẹ́ community in Porto-Novo (Họ̀gbọ́nu) represents a unique historical convergence of Gun (Alada-Ewe) dynastic structures with an autochthonous and commercial Yorùbá urban elite, fostering a bilingual coastal civilization .
The speech forms of the trans-border Western Yorùbá belong to the Edekiri subgroup of the Yorùboid language family, within the Volta-Niger branch of the Niger-Congo phylum . In African descriptive linguistics, pioneering frameworks by Hounkpati B.C. Capo and subsequent sociolinguistic surveys edited by Angela Kluge established the term Èdè (derived from the Standard Yorùbá lexical item èdè, meaning "language") as the rigorous cover term for this dialect continuum, avoiding the ethnopolitical ambiguities of the exonym Nàgó or the nationalistic restrictions of Standard Nigerian Yorùbá .

Vowel Inventories and ATR Contrasts. While Standard Yorùbá (SY), based on North-West Yorùbá (NWY), operates a seven-vowel system (/i, e, ɛ, a, ɔ, o, u/), peripheral Western Yorùbá varieties, particularly Ifẹ̀-Togo, Ìdàáṣà, and archaic registers of Ṣábẹ́, preserve elements of an older nine-vowel system incorporating advanced tongue root [±ATR] harmonic distinctions (/i, ɪ, e, ɛ, a, ɔ, o, ʊ, u/) . Vowel harmony strictly regulates prefixation and verbal morphology across lexical roots .
Consonantal Shifts: The Alveolar-Postalveolar Fricative Split. In standard North-West Yorùbá, the voiceless postalveolar fricative /ʃ/ (orthographically ṣ) occurs regularly . In several Western Yorùbá varieties, particularly central Ìdàáṣà, Iṣa, and localized Ṣábẹ́ lects, this sound undergoes systematic de-palatalization, surfacing as the voiceless alveolar fricative /s/ . Conversely, in Ifẹ̀-Togo, unique consonantal mutations occur where proto-phonemes shift under areal contact with neighboring Gbe and Gur languages .
High Tone Syllable and Syntactic Deletion. Unlike Standard Yorùbá, which utilizes an overt High Tone Syllable (HTS) subject marker between nominal subjects and subsequent verbs, Western Èdè varieties frequently delete the HTS marker entirely or resolve the hiatus through specific vocalic lengthening without tonal modification .

A major debate in West African linguistic historiography centers on the origins and connotations of the glossonym and ethnonym Nàgó . Historian Olabiyi Babalola Yai and geographer John Igue demonstrate that the term was originally employed by Fon- and Gbe-speaking populations as an external label for Yorùbá groups along their eastern and northern frontiers .
During the Atlantic slave trade, French slave traders and colonial officials adopted Nago to designate all Yorùbá-speaking captives shipped from the Bight of Benin ports (such as Ouidah, Porto-Novo, and Jaquin) to Saint-Domingue (Haiti), Cuba, and Brazil .
While British colonial authorities in Nigeria institutionalized the term Yorùbá (originally an Ọ̀yọ́-Hausa designation) for the entire ethnolinguistic group, French colonial administrators in Dahomey codified Nago as an official ethnic classification . Today, while many Western Yorùbá intellectuals and political leaders identify with the Pan-Yorùbá ethnonym, rural populations in Benin and Togo continue to use Nàgó alongside specific subgroup endonyms (Cabe, Idaaca, Ife, Isha) .
The political architecture of the Western Yorùbá kingdoms combined sacred monarchical authority (Ọba) with representative lineage councils, royal electoral colleges, and cross-cutting ancestral associations . Unlike the metropolitan Ọ̀yọ́ Empire, which developed extensive imperial administrative apparatuses and provincial resident governors (Ajélé), the Western Yorùbá polities functioned as independent city-states, confederations, and autonomous chiefdoms .

In Ilé-Kétu, the Alákétu was elected rotationally from five recognized royal families: Alápòkùn, Magbo, Aro, Mèfù, and Mùsò . Royal power was strictly balanced by the Kóbalédè (literally, Kọ́-ọba-lẹ́dẹ̀, "Teach the King How to Speak"), a supreme administrative council composed of the hereditary chiefs representing the major territorial quarters of the capital .
The Kóbalédè acted as the supreme court of the realm and held the constitutional power to restrain royal overreach . Religious checks were exercised by the Alápìní and the custodians of the royal ancestral shrines, ensuring that the monarch governed in accordance with ancestral custom (ìṣẹ̀ṣe) .
In the Kingdom of Ṣábẹ́, political centralization emerged through the settlement of the Babagídàí dynastic group . Oral histories collected by Biodun Adediran indicate that Babagídàí, a warrior-hunter migrating from the Niger-Ọ̀yọ́ frontier zone, integrated the indigenous agricultural clans (the Ola and Ehin groups) through calculated marriage alliances and military protection .
The resulting political structure established the Oníṣábẹ as the paramount sovereign, supported by an executive council of provincial chiefs known as the Ilù . To prevent dynastic usurpation and balance power, territorial governorships were distributed among collateral branches of the royal lineage stationed at strategic frontier garrison towns, such as Kaboua and Ouèssè .
The political organization of Ìdàáṣà developed around a defensive confederacy of fortified hill settlements . The supreme monarch, styled the Jagun or Olófin, presided over an assembly of autonomous clan chiefs representing each of the forty-one inselbergs .
Each hill maintained its own administrative defense force, food granaries, and specialized shrines devoted to local earth spirits and the national deity Nàná Bùkúù . When external military threats arose, particularly Dahomean invasion columns, the Jagun convened the supreme council of hill chiefs to coordinate collective guerrilla warfare and mountain defense strategies .
The religious institutions of the trans-border Western Yorùbá are characterized by the preservation of archaic Yorùboid cosmologies, the veneration of prominent sacred topographies, and the historical development of institutionalized masking complexes .

The Gẹ̀lẹ̀dẹ́ festival is an artistic, judicial, and spiritual institution that originated in the Western Yorùbá region, specifically along the Kétu-Ṣábẹ́-Anàgó frontier, before diffusing eastward into Ẹ̀gbádò, Àwórì, and Lagos territories . Staged annually during agricultural transitions or community emergencies, Gẹ̀lẹ̀dẹ́ honors the supreme spiritual and reproductive powers of women, collectively addressed as Àwọn Ìyá Wa ("Our Mothers"), Ìyàmi Òṣòròngà, or the ancestral matriarchs .
The masquerade pairs elaborate, hand-carved polychrome wooden headdresses displaying complex scenes of daily life, morality, and satirical social commentary with synchronized athletic dancing, poetic chants (ẹ̀fẹ̀), and intricate polyrhythmic drumming . Recognized by UNESCO in 2008 as a Masterpiece of the Oral and Intangible Heritage of Humanity, Gẹ̀lẹ̀dẹ́ remains a vital cross-border institution that unites communities in Benin, Togo, and Nigeria through shared lineages of carvers, dancers, and master drummers .
Central Benin, particularly the Ìdàáṣà and Ṣábẹ́ regions, represents the primary epicenter for the veneration of Nàná Bùkúù (Nana Buruku), an ancient primordial deity associated with the earth, longevity, healing, and sovereign retribution .
Unlike many Òrìṣà whose cults utilize iron instruments (Ògún), Nàná Bùkúù strictly prohibits the use of iron knives or metal tools in her ritual sacrifices, requiring instead bamboo, wooden, or clay ceremonial implements . The major central shrine located in Dassa-Zoumè attracts devotees and initiates from across Benin, Togo, Nigeria, and the transatlantic diaspora, maintaining a trans-border pilgrim economy .
Geological formations occupy a central role in Western Yorùbá religious ontology . In Dassa-Zoumè, the forty-one inselbergs are treated as living ancestral entities and territorial protectors, with annual libations offered to the mountain deities who shielded the population during historical wars .
Similarly, in Atakpamé (Togo), the seven surrounding sacred hills, notably Òkè Èkpà, Òkè Agẹmọ, Òkè Ọmíkòsí, and Òkè Batabali, are revered as spiritual guardians that provided divine intervention during the military confrontations of the seventeenth and eighteenth centuries .
Western Yorùbá oral literature comprises dynastic praise poetry (oríkì), historical migration chants, proverbs (òwe), and incantations (ọfọ̀) that preserve political memory and philosophical worldviews .
The following dynastic praise poem celebrates the ancient citadel of Ilé-Kétu, its unbreachable fortifications, and its mythic foundation under the royal dynasty of Ṣóipàsán .
Kétu ọmọ a pè kùrù bí eji.
Ilé Kétu, ìlú Òpó Ṣóipàsán,
Kétu ọmọ Àkàbà Ìdènà,
Èsùrú a b’ìṣu kùrù-kùrù l’ọ́gbà.
Ọmọ a f’agbára kọ́ ’mú odi,
A kì í rí’bi gbé b’orí odi wọ̀ ’lú,
Bí kò ṣe ẹnu bodè Àkàbà Ìdènà.
Kétu, child of those who gather closely together like heavy rain.
Home of Kétu, city of the Pillar of Ṣóipàsán,
Kétu, child of the Àkàbà Ìdènà gateway,
A sweet-yam with tubers clustered densely within the fence.
Child of those who use sovereign strength to build the ramparts of the wall,
No one ever finds a place to climb over the fortified wall to enter the town,
Except through the defensive mouth of the Àkàbà Ìdènà gate.
Kétu, progeny of those who assemble tightly like the gathering storm clouds.
Citadel of Kétu, royal domain of the great Pillar, Ancestor Ṣóipàsán,
Kétu, born of the unyielding gateway of Àkàbà Ìdènà,
Where sweet yams cluster rich and unyielding behind the garden fences.
Descendants of those whose sovereign might raised the great battlements,
For no enemy could ever scale the soaring citadel walls to breach the city,
Except by yielding before the sentinel mouth of the Àkàbà Ìdènà gate.
(Translation: Anthony I. Asiwaju )
The phrase ọmọ a pè kùrù bí eji operates as a classical Yorùbá metaphor for communal solidarity during military encirclement, comparing the dense population within the fortified walls to dark, concentrated rainclouds that cannot be dispersed by wind .
Àkàbà Ìdènà refers specifically to the historic baked-brick double gatehouse and courtyard that served as the sole monitored entrance into ancient Ilé-Kétu, constructed during the reign of sovereign Edun Aregbe in the eighteenth century . The reference to èsùrú (a variety of sweet yam that grows in tight clusters) symbolizes agricultural self-sufficiency during protracted military sieges .
This ancestral praise text commemorates the foundation of Ṣábẹ́, referencing the integration of the hunter-warrior line of Babagídàí with the indigenous settlement lineages .
Ọmọ Oníṣábẹ́ parí ọlá,
Ọmọ ará Ilé-Babagídàí,
Ọmọ a fi idà kẹ́kẹ́ gba ilẹ̀ l’ọ́wọ́ aláwó.
Ẹlẹ́yẹlẹ́ a f’orí ba ilẹ̀ l’ọ́gbà,
A kì í kọjá Ṣábẹ́ ká má m’ọpárá,
Ọpárá l’ó p’agbègbè pín,
Kí gbogbo ará ilẹ̀ jùmọ̀ mọ̀ pé Ṣábẹ́ l’olú.
Offspring of the Oníṣábẹ́ who completed the zenith of honor,
Offspring of the lineage of the House of Babagídàí,
Offspring of those who used the sharpened sword to take the territory from the land priests.
Keepers of the sacred birds that touch their heads to the ground in the courtyard,
One cannot pass through Ṣábẹ́ without knowing the Ọpárá River,
The Ọpárá River it is that divides the border territories,
So that all dwellers of the land together recognize that Ṣábẹ́ is the sovereign head.
Descendants of the Oníṣábẹ́ who attained the supreme heights of royal prestige,
Sons and daughters of the ancestral House of Babagídàí,
Who by the resolute blade of the sword established dominion alongside the ancient land custodians.
Custodians of the sacred birds that bow their heads within the palace courts,
No traveler traverses the land of Ṣábẹ́ without acknowledging the mighty Ọpárá River,
For the Ọpárá is the eternal river that demarcates the great frontier,
Proclaiming to all who dwell within the land that Ṣábẹ́ reigns supreme.
(Translation: Biodun Adediran )
The term aláwó in this context refers historically to the pre-dynastic autochthonous earth-priests (Ola and Ehin clans) who held ritual custody of the land before the arrival of the Babagídàí immigrant hunters .
The Ọpárá River is celebrated not merely as a geographic landmark, but as the natural international and imperial boundary line that separated Western Yorùbá polities from metropolitan Ọ̀yọ́ and subsequent European colonial spheres .
The following philosophical proverb is widely cited across Western Yorùbá border communities in Benin and Nigeria to emphasize kinship ties that transcend artificial political borders .
Bí odò bá kún, kò le dá ẹbí mẹ́jì;
B’ó pẹ́ títí, àwọn ọmọ ìyá á rí ara wọn.
If river happens to swell, it cannot split family into two;
If it takes long time, the children of mother will surely see themselves.
Though the swollen river may flood its banks, it can never sever the bond of a single family;
No matter how prolonged the separation, the children of one mother will always find their way back to one another.
(Translation: Anthony I. Asiwaju )
This proverb is deployed in social discourse to reassert shared lineage (ọmọ ìyá) across modern territorial and administrative divisions . In borderland diplomacy, speakers use it to rebuke border officials or politicians who attempt to disrupt family gatherings, chieftaincy installations, or funeral ceremonies across the Nigeria-Benin frontier .

Oral traditions, dynastic genealogies, and regional archaeological surveys indicate that the peopling of Western Yorùbaland occurred through successive waves of population movements from the central Yorùbá interior beginning between the twelfth and fourteenth centuries . The foundational dynastic migrations associated with Ṣóipàsán established the fortified capital of Ilé-Kétu, which emerged as a major primary state in the western savannah-forest mosaic .
Simultaneously, hunter-warrior lineages associated with Babagídàí consolidated the Kingdom of Ṣábẹ́, while scattered agricultural and priestly groups in central Benin coalesced around the granitic hill clusters of Dassa-Zoumè (Ìdàáṣà) and Bantè (Iṣa) for defensive security .
Further west, during the fifteenth and sixteenth centuries, migrations moving through the transitional settlement of Ìjá-Òkú crossed the Mono River into present-day central Togo, establishing the Ifẹ̀-Togo settlement of Atakpamé amidst the Seven Hills . In the far north, specialized hunter-cavalry groups from the Ọ̀yọ́ sphere established the isolated Mokolé enclave in the Kandi region of the Borgu frontier .
During the seventeenth and eighteenth centuries, the expansion of the Ọ̀yọ́ Empire dramatically restructured the geopolitical balance of Western Yorùbaland . While Ọ̀yọ́ subjugated the Kingdom of Dahomey to tributary status following military campaigns between 1726 and 1748, relations between Ọ̀yọ́ and sovereign kingdoms such as Kétu and Ṣábẹ́ operated through diplomatic parity, dynastic respect, and mutual non-aggression treaties . Kétu and Ṣábẹ́ retained complete internal sovereignty while serving as crucial trade corridors linking the metropolitan Ọ̀yọ́ interior to coastal trading ports .
A decisive international military event occurred in 1764 with the Battle of Atakpamé in central Togo . Seeking to expand its trade monopoly toward the coast, the Ashanti Empire launched an army eastward across the Volta River . In response, the Ọ̀yọ́ Empire deployed cavalry divisions alongside allied contingents from Dahomey and the Akan state of Akyem .
The allied forces engaged and crushed the Ashanti army near Atakpamé, killing the Juabenhene (ruler of the royal Juaben clan of Ashanti) and halting westward expansion, securing the territorial position of the Ifẹ̀-Togo and allied western polities .
The collapse of the Ọ̀yọ́ Empire during the 1830s removed the imperial military shield that had restrained Dahomean expansionism . Under Kings Ghezo (reigned 1818-1858) and Glele (reigned 1858-1889), the Kingdom of Dahomey launched aggressive slave-raiding and conquest campaigns eastward against Western Yorùbaland .

The Fall of Ilé-Kétu (1883 and 1886). In 1883, King Glele launched a massive assault on Ilé-Kétu, exploiting internal political factions . Although the city resisted behind its fortified walls, a second surprise attack in 1886 resulted in the catastrophic breach of the citadel, the capture and suicide of the Alákétu, and the mass enslavement or dispersion of the Kétu population into neighboring regions .
The Ìdàáṣà Hill Resistance. The Ìdàáṣà utilized their forty-one inselbergs to wage protracted defensive guerrilla warfare, storing food supplies in mountain caves and raining boulders down on Dahomean infantry columns . While Dahomean armies sacked lowland farmsteads, the mountain redoubts of Dassa and Bantè remained largely unconquered .
The Ṣábẹ́ Devastation. Located in open savannah, the Kingdom of Ṣábẹ́ suffered severe devastation from both Dahomean incursions and Fulani-Nupe raiders from the northeast, forcing the Oníṣábẹ and large segments of the population to seek temporary refuge in the defensive hills of Savè or across the Ọpárá River into Nigeria .
The geopolitical map of Western Yorùbaland was radically altered by the Anglo-French Agreement of 10 August 1889, which established the international boundary between French Dahomey and British Nigeria without regard for historical ethnic boundaries . The boundary was formally surveyed and demarcated on the ground by the Joint Franco-British Boundary Commission between 1895 and 1896 .
Simultaneously, imperial Germany established the protectorate of Togoland, annexing the Ifẹ̀-Togo and Northern Nàgó around Atakpamé and Kambolé, which was later transferred to French mandate administration following the defeat of Germany in World War I .

+----------------------------------------------------------------------------------+
As documented in the historical research of Anthony I. Asiwaju, the Western Yorùbá experienced radically divergent colonial realities :
The French Sphere (Dahomey/Togo). The French colonial regime implemented direct rule, degrading traditional sovereigns into subordinate tax collectors (chefs de canton), imposing harsh forced labor (prestation), levying heavy poll taxes, and enforcing summary criminal penalties under the Régime de l'Indigénat . Traditional institutions such as the Alákétu and Oníṣábẹ thrones were marginalized or temporarily suspended .
The British Sphere (Nigeria). The British administration applied Lord Lugard's system of Indirect Rule through the Native Administration system, protecting traditional crowned rulers (Ọba) and allowing the localized continuation of customary legal courts .
Cross-Border Protest Migrations. In direct response to French colonial exactions, compulsory military conscription during World War I, and forced labor, entire Western Yorùbá communities fled eastward across the border into British Nigeria .
These protest migrations led to the establishment of thriving borderland boom towns in southwestern Nigeria, such as Òkè-Àgbẹ̀dẹ̀ and Moriwi in the Imeko-Afon district of Ogun State, founded by Kétu and Ṣábẹ́ refugees seeking British legal jurisdiction while maintaining ancestral farm holdings across the French line .
With the achievement of national independence in 1960 by the Republic of Dahomey (renamed the Republic of Benin in 1975), the Togolese Republic, and the Federal Republic of Nigeria, the colonial borders were maintained under the Organization of African Unity's principle of uti possidetis juris . Despite strict international border controls, currency divergence (the West African CFA franc versus the Nigerian Naira), and differing official national languages (French versus English), the Western Yorùbá have maintained institutional, religious, and economic cohesion .

Monarchical Diplomacy and Royal Networks. The traditional monarchs of Benin, notably the Alákétu of Kétu and the Oníṣábẹ of Ṣábẹ́, regularly participate in Pan-Yorùbá royal conferences, maintaining formal diplomatic ties with the Ọọ̀ni of Ilé-Ifẹ̀ and the Aláàfin of Ọ̀yọ́, and visiting the border communities in Nigeria .
Economic Border Markets. The border corridor between Benin and Nigeria operates as an economic trading network, with major border markets at Kétou, Pobè, Adjarra, and Ilara facilitating the transshipment of agricultural commodities, consumer goods, and informal petroleum distribution (kpayo) .
Linguistic Codification and Intangible Heritage. Since the 1990s, national literacy agencies, such as the Centre National de Linguistique Appliquée (CENALA) in Benin and SIL International, have codified standardized orthographies for the Ede languages (Ede Cabe, Ede Idaca, Ede Ica, and Ifẹ̀-Togo), publishing reading materials and broadcasting localized radio programs that reinforce cultural preservation alongside Standard Yorùbá literacy .
The study of the trans-border Western Yorùbá occupies a central position in West African historiography, characterized by several enduring scholarly debates .

+-------------------------+----------------------------------+----------------------------------+
Canonical Pan-Yorùbá historiography, represented by Reverend Samuel Johnson and colonial-era ethnographer Geoffrey Parrinder, treats Kétu and Ṣábẹ́ as primary kingdoms established by the biological sons of Odùduwà who departed directly from Ilé-Ifẹ̀ with royal beaded crowns .
Conversely, historian Biodun Adediran challenged this model, arguing on the basis of extensive oral historical and dynastic praise analysis that the Western Yorùbá kingdoms were secondary states . Adediran demonstrated that the areas were already settled by organized pre-dynastic populations, and that political centralization resulted from subsequent waves of migrant hunters and warriors moving from the Ọ̀yọ́-Niger perimeter who later adopted the ideological mantle of Ifẹ̀ dynastic legitimacy to consolidate their political rule .
Scholars disagree regarding the legitimacy of using the term Nàgó to describe the Western Yorùbá . French colonial historians, such as Robert Cornevin, treated the Nago as an autonomous ethnic group distinct from the Nigerian Yorùbá .
In contrast, John Igue and Olabiyi Babalola Yai argued that Nàgó was an external, derogatory Gbe exonym (associated in early Fon usage with "louse" or "stranger") that was adopted by European slave traders and codified by the French administration to divide the cross-border Yorùbá population and discourage Pan-Yorùbá solidarity .
The long-term socio-political effect of the 1889 Anglo-French partition forms a central debate in African borderlands studies . Anthony I. Asiwaju formulated the concept of "vivisected ethnic groups", arguing that the border imposed institutional fractures, separated families, and created divergent legal and linguistic identities among homogeneous populations .
Conversely, political scientists and anthropologists, such as William F.S. Miles, argue that while the border created administrative obstacles, borderland populations actively transformed the partition into an economic and strategic asset, exploiting price differentials, smuggling corridors, and dual citizenship rights to maximize cross-border mobility and economic agency .
