The Àwórì, the Yewa and the Ìbàràpá

Standard accounts of the Yoruba move from Ifẹ̀ to Ọ̀yọ́ to Ìbàdàn and the coastal states, and the groups in this file fall through the gaps. The Àwórì are usually mentioned only as an aside to Lagos, though they hold the land under it. The Ẹ̀gbádò appear as an Ọ̀yọ́ trade corridor rather than as a people, and they changed their own name in 1995 partly because of how they were described. The Ìbàràpá appear, if at all, as a footnote about twins. Each has a history worth stating on its own terms.

The Àwórì

The Àwórì are a Yoruba subgroup with their own dialect, occupying the southwestern corner of Yorubaland in present-day Lagos and Ògùn states 1.

The floating calabash

The origin tradition is the mud plate. Olófin, also called Ògúnfúnminíre, left Odùduwà's palace at Ilé-Ifẹ̀ with his followers, carrying a floating calabash or mud plate given him by Odùduwà with instructions to set it on the water and follow it until it sank 2. The first stop after Ifẹ̀ was near Olokemeji, close to present-day Abẹ́òkúta. The plate then stopped at Ìṣerí and stayed there two hundred and eighty-nine days, long enough that many assumed it had sunk for good. It resumed, and Olófin followed it until it finally sank at Idumota in Lagos 2.

The name is glossed from awo ti rì, the plate has sunk, which is what Olófin is said to have answered when his people asked where it was 2.

Two notes on this. The 289-day figure and the Olokemeji stop come from popular-press retellings of Àwórì oral tradition rather than from academic sources, and should be attributed as such 2. And the standard reference article on the Àwórì contains no origin narrative at all 1, which is itself worth recording: the group's own foundation story circulates almost entirely outside the reference literature.

Towns and titles

Àwórì towns include Ìṣerí, Òtà, Lagos (Èkó) and Àgége, with settlement extending into the Badagry area 1, and Ìlogbo and Ado-Odo also fall within Àwórì territory 3.

Òtà is historically the capital of the Àwórì 4, and its ruler is the Olótà of Òtà, currently Ọba Adéyẹmí AbdulKabir Obalanlege 5.

Òtà's founding is contested between two directly opposed claims.

The Osolo claim dates the formal founding of Òtà to the fifteenth century as an Àwórì settlement by Osolo, one of Olófin's sons, who with his brother Talabi migrated from Idimu-Olofin and established the community at Idi-Egun in the Isoloishi quarters after stops at Oke-Ata and Ibaragun; the first crowned Olótà was Ọba Akinsewa Ogbolu, Osolo's son, installed in 1621 6.

The pre-Ògúnfúnminíre claim holds that the traditional institution at Òtà dates to the Ifẹ̀ Oodaye or Ọ̀rúnmìlà period, with Ọ̀rúnmìlà meeting a woman ọba named Iyarigimoko Otayo, titled the original mother of Òtà and the first Olótà in history, on which account Òtà stands first, long before the arrival of Ògúnfúnminíre and his group between the fifteenth and seventeenth centuries 7.

These cannot both be right and the sources give no basis for choosing. The pattern is familiar from Ifẹ̀ and Ondó: an incoming dynastic claim and an autochthonous claim, with the second asserting a female founder displaced by the first. The reference literature notes the tradition that Òtà is a very ancient city ranking behind Ilé-Ifẹ̀ only 4.

Òtà's festivals are the Egúngún festival, with the town described as the centre of Egúngún observance in Yorubaland, and the Iganmode Cultural Festival, held annually in December since 1992 and showcasing Àwórì heritage 4.

Òtà today is the capital of Ado-Odo/Ota local government area and part of metropolitan Lagos, with a population of about 163,783 4. Sango-Ota had the third-largest concentration of industry in Nigeria as of 1999, with breweries, vehicle manufacturing and pharmaceuticals along the Lagos-Abẹ́òkúta expressway, and it hosts Covenant University and Bells University of Technology, together with St James Cathedral established in 1842 4.

The colonial description

A 1935 anthropological report described the Àwórì as engaged primarily in farming and fishing and speaking what it called a slurred dialect of Yoruba 1. That characterisation is the report's own and is a good specimen of the colonial ethnographic register: a dialect difference recorded as a defect. It should be quoted as an artifact of its moment, not repeated as description.

Why the Àwórì matter

The Àwórì are the case that most clearly separates land ownership from political power in Yoruba institutions. The Lagos ìdejò chiefs, the white-cap land-owning chiefs treated in the Lagos file, are Àwórì lines descended from Olófin, and their claims underlie a substantial body of Nigerian land law. A group can be politically marginal and still hold the freehold, and in Lagos that is exactly what happened.

The Yewa, formerly the Ẹ̀gbádò

The name and the 1995 change

Ẹ̀gbádò parses as Ẹ̀gbá l'ódò, Ẹ̀gbá by the river 8. In 1995 the Ẹ̀gbádò chose to rename themselves Yewa, after the Yewa river running through their territory, whose own name derives from the òrìṣà Yewá 8.

The process is documented: following a report by a Yewa think tank of educated elites and thought leaders, it was unanimously resolved that the people formerly called Ẹ̀gbádò would thenceforth be known as Yewa 9.

The obvious inference from the etymology, that a name defining the group as a riverine appendix to the Ẹ̀gbá was felt to subordinate them, is not stated as motive in the sources consulted. Report the etymology and the resolution and leave the inference to the reader.

This is a rare and well-documented case of a Yoruba subgroup consciously renaming itself in the modern period, and it is worth noticing as evidence that subgroup identity is not fixed and is subject to deliberate revision.

Territory, towns and rulers

The Yewa occupy Ògùn West Senatorial District across four local government areas, Yewa South, Yewa North, Imeko-Afon and Ipokia, with a population of about 907,370 8. Their towns include Ìlàrò, Àyétòrò, Ìmẹ̀kọ-Afon, Ado-Odo, Ìpòkìá and Ìgbógìlà, established between the eleventh and eighteenth centuries to take advantage of the trade routes running from the inland Ọ̀yọ́ empire to the coast at Porto-Novo 8.

Traditional rulers bear the title Olú, with the Olú of Ìlàrò the paramount figure 8. Ìlàrò was founded in the eighteenth century by a warrior named Aro, who migrated from Ọ̀yọ́ and settled at Igbo Aje, and the name derives from Ilu Aro, Aro's settlement 10. The Olú of Ìlàrò has doubled as President and Paramount Ruler of Yewaland since 1993 by consensus among the crowned heads of the Yewa towns, which is to say the paramountcy was agreed two years before the renaming 109. The current holder is Ọba Kẹ́hìndé Gbadéwọlé Olugbenle, from 14 April 2012 10.

Titles for Ìmẹ̀kọ and Àyétòrò could not be verified in the sources consulted and are not supplied here.

The corridor

The Yewa historical role is the Ọ̀yọ́ corridor to the sea. They occupied the critical ground between the empire and the coastal ports, and Ọ̀yọ́ could not deploy its cavalry to protect the routes because of tsetse fly and the terrain, which forced reliance on the local groups to manage commerce toward the coast 8.

That is a strong position and it is why the corridor towns exist. It is also a vulnerable one: a group whose function is to move other people's goods through its own territory is the first casualty when the trade is contested, and the Ẹ̀gbádò towns were fought over repeatedly by Ọ̀yọ́, Dahomey, Abẹ́òkúta and eventually the British.

Ìlàrò is the headquarters of Yewa South local government area, with about sixty thousand people on a 2015 estimate over roughly nine square kilometres, and hosts the Federal Polytechnic Ilaro, established 1979, together with the State High Court and Magistrate Courts 10. Ìlàrò originates the Bolojo and Gẹ̀lẹ̀dẹ́ dances and hosts the annual Orona Ilaro festival 10. The Gẹ̀lẹ̀dẹ́ association is significant: the Gẹ̀lẹ̀dẹ́ masquerade of the Ẹ̀gbádò and Kétu region is on UNESCO's Representative List of the Intangible Cultural Heritage of Humanity, and it is treated in the arts section.

The Ìbàràpá

The Ìbàràpá are a Yoruba subgroup in the southwestern corner of Ọ̀yọ́ State 11.

The name derives from a local melon cultivar known as egusi ibara, for which the region was recognised by neighbouring groups because of its extensive cultivation 11. A subgroup named for its crop is unusual and it is a useful corrective to the assumption that Yoruba subgroup names are always dynastic or toponymic.

Ìbàràpá Méje, the seven towns, are Igangan, Èrúwà, Àyété, Tápà, Ìdẹ̀rẹ, Igbó-Òrà and Lanlate, anchoring roughly a hundred and twenty surrounding villages 11. Seven is the canonical count and lists that give five are incomplete.

Origins. The Ìbàràpá originated in the old Ọ̀yọ́ empire and migrated to their present location as dissidents from Ọ̀yọ́ or as refugees fleeing warfare and slave raids after the empire's collapse 11. Tápà is the exception: it comprises Nupe refugees who fled Fulani jihadists from the north, and is therefore not of Ọ̀yọ́-Yoruba origin like the others 11. Tápà is in fact the Yoruba word for Nupe, so the town's name records what it is.

Territory. About 2,496 square kilometres, or 8.77 percent of Ọ̀yọ́ State, roughly a hundred kilometres north of Lagos and ninety-five west of Ìbàdàn, distributed across three local government areas created in 1996: Ibarapa North (Igangan, Tápà, Àyété), Ibarapa Central (Ìdẹ̀rẹ, Igbó-Òrà) and Ibarapa East (Lanlate, Èrúwà) 1112.

Status disputes. After independence in 1960 there was debate over merging Ìbàràpá into Ògùn State, and the federal government resolved in 1976 that it would remain in Ọ̀yọ́ State 11. Within Ìbàràpá, Èrúwà was recognised in pre-colonial times by the Aláàfin of Ọ̀yọ́ as the leading town of the district, a position it retained through the colonial era 13.

Titles. Èrúwà's ruler is the Elérúwà, currently Ọba Samuel Adébáyọ̀ Adegbola, Ajobo Olurin I, presented with the staff and instruments of office on 6 March 2025 14. Igbó-Òrà's ruler is the Olú of Igbó-Òrà, previously styled Baálẹ̀, currently Ọba Jimoh Olájídé Titiloye, installed in 2019 15. Titles for Ìdẹ̀rẹ, Tápà, Àyété, Igangan and Lanlate could not be verified and are not supplied.

Èrúwà's name is glossed as pieces of yam are available here, and it is the headquarters of Ibarapa East local government area 13.

Igbó-Òrà and the twinning question

Igbó-Òrà was founded by Obe Alade, a descendant of the Aláàfin of Ọ̀yọ́, after migrating from Ọ̀yọ́ town 15. It is the headquarters of Ibarapa Central local government area, comprising Igbó-Òrà with seven wards and Ìdẹ̀rẹ with three, about eighty kilometres north of Lagos, with 72,207 people at the 2006 census 15. A frequently quoted 2017 figure of 278,514 is implausible as town growth and most likely covers the local government area rather than the town.

The town is widely called the twin capital of the world, and the underlying measurement is real while the causation is not established.

What is measured. Patrick Nylander, a British gynaecologist, published "The Twinning Incidence in Nigeria" in 1979, and between 1972 and 1982 recorded an average of forty-five to fifty sets of twins per thousand live births in the region 16. The peer-reviewed literature describes Igbó-Òrà as having the highest dizygotic twinning rate in the world at forty-five per thousand live births, against a global average around twelve per thousand 17. A much higher figure circulates, about a hundred and fifty-eight per thousand against five per thousand in Europe, and it is not the peer-reviewed rate; prefer forty-five 18.

What is not established. Nylander suggested in 1978 that a dietary substance, possibly yams, might explain the rates 16. The community disagrees. A qualitative study of local perceptions found that residents do not consider yams causal, and beyond the will of God and heredity attribute twinning to okra leaves and cassava 17. More recent theorising points to phytoestrogens present in both cassava and yams 18. The reference literature summarises the position as a possible chemical link to a widely consumed tuber with no definitive link established, alongside proposed genetic factors 15. Research is ongoing 1920.

The town holds an annual twins festival and has been covered by NPR, Al Jazeera and TRT 21. The correct way to state the claim is that Igbó-Òrà celebrates a claim to be the twin capital of the world, that the claim rests on a real and unusually high measured dizygotic twinning rate, and that the cause is unexplained.

There is a second thing worth saying, which belongs to the religion section but bears on the town. Yoruba culture has an elaborate and old body of practice around ìbejì, twins, including the ère ìbejì figures carved for a deceased twin. The high twinning rate and the depth of the twin cult are usually presented as connected, and the direction of any connection is not demonstrated. Igbó-Òrà is where that question is most sharply posed.
