Frequently Asked Questions
Direct answers to the questions readers actually ask, including the uncomfortable ones about human sacrifice, the slave trade, initiation, appropriation and faith.
Direct answers, with sources, including the questions people are reluctant to ask out loud. Where an answer is uncomfortable it is given anyway, and where the evidence does not settle a question that is said rather than covered over.
Basics
Is it a religion or a culture?
Both, and the boundary between them is drawn differently by different people, which is why the question generates so much disagreement.
There is a religious system: òrìṣà, Ifá, ẹbọ, priesthoods, shrines, initiation, a cosmology. There is a cultural inheritance: language, oríkì, proverbs, naming, music, dress, food, kinship, festival, forms of respect. The two were not separated in the pre-nineteenth-century arrangement, and the separation is a modern accommodation made necessary by mass conversion to Christianity and Islam.
That accommodation is real and it works for most Yorùbá people. Someone can perform oríkì, name a child by traditional rules, attend a festival and observe funeral custom while being a committed Christian or Muslim, on an internal distinction between the cultural and the religious. Whether that distinction is coherent is exactly what the disagreement is about, and this corpus does not settle it. It is worth noticing that many Yorùbá cultural forms carry the older cosmology inside them, particularly the language, so the separation is never quite clean.
How many Yorùbá people are there?
Roughly fifty million or above, concentrated in southwestern Nigeria with substantial populations in Benin and Togo, plus a diaspora . The most defensible figure is Ethnologue's language count of around forty-eight million first-language speakers as of 2023 . All of these are estimates; Nigeria's last census to publish ethnic disaggregation was 1963.
Do Yorùbá people still practise the traditional religion?
A small minority practise it as their primary religious identity. A much larger number retain cultural forms. An undetermined but substantial number make instrumental recourse to diviners, herbalists and traditional healers while identifying as Christian or Muslim, which is more common than it is admitted. Survey figures showing traditional religion at well under one percent of Nigerians measure self-identification on a question where Christian and Muslim are the socially available answers, not practice .
Is òrìṣà religion dying?
The continental picture and the diaspora picture point in different directions.
In Nigeria, transmission is the problem. UNESCO's assessment at Ifá's inscription was that the priests, most of them elderly, have "only modest means to maintain the tradition, transmit their complex knowledge and train future practitioners" A tradition transmitted by apprenticeship over years does not survive a generation declining to enter it.
Against that, the diaspora traditions in Cuba, Brazil, Trinidad and North America are growing, there is a substantial international interest in Ifá, there is a Yorùbá cultural reclamation movement that includes many people with no intention of practising, and the scholarly literature is larger and better than it has ever been. What is not clear is whether growth in these forms compensates for loss in the form that was transmitted by lineage in Yorùbá towns, and there is no reason to assume it does.
The uncomfortable ones
Was there human sacrifice?
Yes, in specific documented contexts, and the scale was also exaggerated by observers with an interest in exaggerating it. Both statements are true and the honest answer requires both.
What is documented: human sacrifice existed in Yorubaland principally in connection with royal funerals and with communal crisis, and it is attested across a number of West African societies in the same period . The Yorùbá case has been studied in detail for eastern Yorubaland in the late nineteenth century by Olatunji Ojo, who situates it in relation to slavery, economic inequality and chiefly privilege, and traces its ending to conflict between the chiefs who practised it and their opponents among slaves, Christians and British officials, in the context of the end of the Yorùbá wars and the approach of colonial rule . The victims were principally slaves and captives, which means the practice was continuous with the institution of slavery rather than separate from it.
What is equally documented: European observers from the fifteenth century onward emphasised and exaggerated human sacrifice in West African societies in order to define Africans as barbaric and to justify conquest, and this is the standard methodological caution in the scholarship .
Three points of proportion. It was occasional and institutionally specific rather than a routine feature of religious life; the ordinary Yorùbá person's ordinary religious activity involved kola nut. It was ended in the late nineteenth century and is not a live practice. And the analytic category "human sacrifice" was applied selectively to non-European societies, in a period when European states were conducting public executions and had recently ended judicial torture, in a way that did a good deal of its work through that selectivity.
What this does not license is the reverse move of denying it happened. It happened.
What about the slave trade, and did the Yorùbá participate?
Yes, as sellers as well as being devastated as victims, and this corpus does not soften it.
The Yorùbá entered the Atlantic trade late and left it heavily, because the nineteenth-century wars generated the captives. Model-based estimates from the Trans-Atlantic Slave Trade Database put roughly 121,000 people exported from the Yorùbá-speaking region between 1817 and 1836, roughly 42 percent to Brazil and roughly 40 percent to Cuba . Captives taken in Yorùbá wars by Yorùbá forces were sold into that trade, by Yorùbá states and Yorùbá merchants, and the trade and the wars fed each other: guns bought with captives produced more captives.
Domestic slavery within Yorubaland also expanded during the same period, and Ojo's work on human sacrifice is inseparable from that fact, since the people sacrificed were largely enslaved .
Two things that are true and are not excuses. The demand that drove the volume was Atlantic and European, and the wars that produced the captives had causes including the collapse of Ọ̀yọ́ and the pressure from Ilọrin that were not simply a response to that demand. And the same period produced the Sàró, Yorùbá people liberated from slave ships and returned from Freetown, who brought back Christianity, literacy and the beginnings of Yorùbá print, so the trade also shaped the culture that came after it.
Samuel Àjàyí Crowther, who translated the Bible into Yorùbá and made the decisions that shaped how Yorùbá Christians understood their own inheritance, was himself captured at around thirteen when his town was raided by people from his own region . That is the compressed version of the whole century.
Was the pre-colonial society good?
It was a society, with the ordinary distribution. It had constitutional constraints on kingship that were real and that were captured and abused. It had women's institutions with genuine economic and political authority that colonial administration destroyed. It had slavery, and expanded it. It had law, medicine, art, an intellectual tradition and cities. It had war, and by the nineteenth century the war was catastrophic.
This corpus does not present the pre-colonial past as a paradise, because it was not one and because a reader who accepts that version will eventually find out and will then discount everything else they were told.
About Ifá
Is Ifá fortune-telling?
Not in the sense of predicting fixed future events. UNESCO's formulation is that Ifá "does not rely on a person having oracular powers but rather on a system of signs that are interpreted by a diviner" The procedure produces one of 256 signs, each sign addresses a body of memorised verse, and the verses give narrative precedents which the diviner interprets against the client's situation, usually prescribing an offering and often a change of conduct.
What that does is bring an accumulated body of stored judgment to bear on a present problem, through a randomised selection the diviner does not control, with a prescribed action at the end. Whether it also does what the tradition says it does is a separate question that evidence does not settle.
Is Ifá really binary? Is it a computer?
It is genuinely binary and it is not a computer.
Genuinely binary: eight positions, each resolving to one of two states, produced by a randomising device, giving 2⁸ = 256 signs, each of which is the address of a body of verse. Positional, not a tally. Ordered by seniority. Indexing a corpus in the hundreds of thousands of verses held in human memory. Ron Eglash treats it as among the most developed indigenous mathematical systems and identifies combinatorial reasoning in it; Olu Longe analyses it in terms of binary representation, Boolean algebra and memory addressing; UNESCO refers to the system's mathematical formulas .
Not a computer, and not the origin of computing. Eglash proposed a transmission line from African divination through Arab geomancy to Leibniz and the evidence for that specific chain is weak; historians of mathematics working on Leibniz have found none of the proposed external influences plausible, since the manuscript evidence shows he paid no attention to alternative number systems before developing binary . The careful writers making the Ifá-as-binary case make no origin claim .
The true version is the stronger one. A West African oral tradition independently built a formal binary addressing scheme over an enormous corpus and maintained it without writing. That does not need to be inflated.
Can you use Ifá without believing in it?
People do. The three readings of Ifá, as religion, as a repository of accumulated knowledge, and as a decision procedure that interrupts rumination and brings stored judgment to bear, are separable, and many of the scholars who have documented Ifá most carefully hold the second and third without the first.
What is not honest is presenting a stripped-down version as though it were what practitioners hold. Practitioners hold the religious account, and a reader who takes the intellectual content while calling the religious content superstition is doing something the tradition would not recognise. That may be a defensible position; it should just be stated as one's own rather than attributed to the tradition.
Can I learn Ifá from a book?
You can learn a great deal about it from books, including the published corpus in Abímbọ́lá's and Bascom's transcriptions and the substantial secondary literature. You cannot become a babaláwo from a book, and no book contains the whole system.
Ifá training is a long apprenticeship. The Odù are learned in sequence, particular material is transmitted at particular stages, and some of it is not repeated outside a grove. A source claiming to give you the complete system is telling you something about itself. This corpus marks that boundary rather than filling it in.
Practice, initiation and access
Can you practise without initiation?
Depends on what "practise" means, and the answer differs between the continental and diaspora traditions.
Many Yorùbá people maintain relationships with the òrìṣà of their lineage, make offerings, attend festivals and consult diviners without being initiated into any priesthood. Initiation is required for priestly function, not for participation.
Divining with Ifá is different. Reading the corpus for others is a priestly function requiring initiation and training, and the diaspora traditions in particular are strict about this. There is a considerable amount of material online that presents Ifá divination as something a person can pick up, and practitioners in every branch of the tradition regard that as illegitimate.
The diaspora traditions are generally more formalised about initiation than continental practice, because they had to be: cut off from lineage and place, initiation lineage became the mechanism of continuity and legitimacy in a way it was not on the continent, where a person's belonging was established by birth into a lineage that already had its relationships.
Is it appropriative for a non-Yorùbá person to engage?
The tradition's own most senior public voice says no. Wándé Abímbọ́lá, who holds the title Àwíṣẹ Awo Ni Àgbáyé, world spokesperson for Ifá and Yorùbá religion, has held that Ifá is not for the Yorùbá alone but for all of humanity, and has argued for recognising the validity of all religions and for sharing without forced conversion . That is a position taken from inside the tradition by the person with the strongest claim to speak for it publicly.
Engagement is also not one thing, and the distinctions matter:
Studying it as history, philosophy, art or literature: nobody's position is that this is a problem.
Practising within it, with initiation, a lineage and a teacher: this is the route the tradition itself defines, and the tradition has always incorporated outsiders; the American traditions are constituted almost entirely of people who were not born into Yorùbá lineages.
Practising outside it, taking pieces without initiation, teacher, lineage or obligation, typically assembled from books and the internet: this is what practitioners object to, and the objection is generally not about ethnicity but about the absence of accountability. There is no one to correct you and nothing you owe.
Selling it: divination services, initiations and "Ifá readings" offered commercially by people without standing, of which there is a great deal online. Practitioners are uniformly hostile to this.
There is also a live intra-tradition argument, particularly sharp between continental and diaspora practitioners, about who can validate an initiation and whose lineage counts. That is a dispute among practitioners rather than a question this corpus can resolve.
Can women be initiated into Ifá?
Contested, and actively so. Women hold the title ìyánífá, and there is historical scholarship describing female priestly roles including the Ìyá Mọlẹ̀ and the requirement that royal mothers of Yorùbá rulers hold Ìyáláwo or Ìyánífá titles . As Ifá has grown internationally, particularly in Cuba and the United States, women seeking the highest levels of initiation have challenged a priesthood that had become predominantly male, and this is a real ongoing controversy with positions held strongly on both sides . This corpus reports the dispute and does not adjudicate it.
Women hold priestly authority across òrìṣà practice generally without this being in dispute; the controversy is specific to the highest levels of Ifá.
Faith
Do I have to choose between this and my faith?
No, in the sense that a great many people do not experience a choice, including many of the scholars whose work this corpus cites, who are practising Christians and Muslims. Yes, in the sense that some positions genuinely are incompatible and no amount of framing makes them compatible.
The distinctions that do the work:
Understanding is not commitment. Learning what àṣẹ means, how the Ifá corpus is organised and why Èṣù was mistranslated is knowing something about a body of thought. Nothing about it requires practising it. The fear that examining the material is itself participation in it is a specific product of spiritual-warfare theology rather than a general feature of religious commitment.
Cultural retention is the majority Yorùbá position. Committed Christian or Muslim faith alongside full participation in Yorùbá cultural life is what most Yorùbá people do, and it is not experienced as hypocrisy by the people doing it.
Practice is a different question. Making offerings to an òrìṣà is a religious act and both Christianity and Islam are exclusive on the point. A person who holds that this is forbidden is holding their own tradition's position consistently, and that is not narrowness.
Where the tension is real, it is real. Funerals and chieftaincy are the two occasions where a decision cannot be avoided, and both produce lasting family conflict. This corpus is not going to pretend otherwise.
Does this corpus want me to convert?
No. It does not argue that Yorùbá tradition is true, does not argue that Christianity or Islam is false, and does not have a position on what any reader should do. Its position is that decisions on these questions are better made from an accurate picture of what the tradition contains than from the picture supplied by the demonization, and that supplying the accurate picture is worth doing regardless of what anyone then decides.
Why does the corpus spend so long on the demonization?
Because for a very large number of Yorùbá readers it is the obstacle that sits in front of everything else. A person who has been taught the entire pre-Christian Yorùbá world was satanic has no route to encountering Ifá as a formal system, Yorùbá ethics as ethics, or the Ifẹ̀ sculpture as art, because the category assigned to the whole domain forecloses examining any part of it. The file documents how the category was assigned, with dates and names, and leaves the reader to decide what to do about it.
Practical
Where do I start?
If you are new: the fifteen-minute explainers in this section, then the conceptual map in foundations. Roughly ninety minutes.
If you were taught this heritage was demonic: the demonization file in foundations first, then what Yorùbá tradition is not.
If you came for Ifá as an information system: the Ifá explainer in this section, then the Ifá section.
The learning paths file in this section has four ordered routes with time estimates.
Why is everything written with accent marks?
Because they are part of the spelling. ẹ, ọ and ṣ are separate letters, and the tone marks distinguish words: ra, rá and rà are to rub, to disappear and to buy. Writing Yorùbá without tone is closer to writing English without vowels than to writing English without italics. The pronunciation guide in this section explains the system in about fifteen minutes.
Can I trust this corpus?
Check it. Every substantive claim carries a source marker pointing to a Sources block, the sources are named with URLs where they are open, confidence is marked in each file's frontmatter, and where scholars disagree the positions are named rather than smoothed. Where a source is weak or paywalled and the summary rests on an abstract, the file says so. That is the standard the corpus holds itself to, and a reader who finds it failing that standard anywhere has found a genuine defect.
