The Persecution of Bwiti: Gabon and Equatorial Guinea, 1930-1950

A Nail, a Barrel, and a River

Nkogho Mba Ndzambiavanga was a carpenter working on a construction site in N'toum, Gabon, owned by a Frenchman named Zophine. Zophine hated Bwitists. When he found out Nkogho Mba was one, he and two other white men caught him on his way home from a ngozé, a night ceremony, in the nearby village of Alarmitang, and locked him in the tool shed. His body turned up in the river a few days later, inside a barrel, with a nail driven into his skull. Zophine was never sentenced for it. He was simply sent back to France.

This happened sometime in the 1930s or 1940s in French Equatorial Africa, part of a documented campaign of persecution against the Bwiti religion that most people who have heard of iboga and Bwiti have never heard about. The Italian ethnobotanist Giorgio Samorini reconstructed this history from colonial archives, missionary correspondence, Spanish and French trial records, and interviews he conducted himself in Gabon between 1991 and 2022, publishing the findings as the fifth installment of a research series in the Antrocom Online Journal of Anthropology in 2025. What the documents show is not vague cultural friction. It is a coordinated effort by church and colonial state, in two different countries, to destroy a religion, using methods that included whipping, hanging, rape, and crucifixion.

The Report That Started It

The persecution had a paper trail with an identifiable starting point. In 1930, the governor of Gabon, a colonial administrator named Vuillaume, wrote a thirty-page manuscript on the customs of the Fang (referred to in the document by the period term Pahouin). Five of those thirty pages were devoted to condemning Bwiti. Vuillaume called it "a dangerous religious manifestation," writing that "the practices of the Bwiti are harmful to the races that adopt it, they cause mental disturbances that annihilate all will and the race becomes brutalised."

Samorini is careful to note that even basic facts about this report are contested: French Wikipedia lists a different administrator, Marie Joseph Jules Pierre Bernard, as holding the governorship in 1930, with Vuillaume only taking the post in 1943-1944. The confusion does not change what the document said or what it triggered. Missionaries saw the Fang version of Bwiti, which had syncretized with Christian symbolism, as a heresy actively competing for converts. Colonial administrators saw it as something more dangerous: a native institution that fostered exactly the kind of ethnic pride and social cohesion that could organize resistance to colonial rule. Samorini's phrase for this convergence is direct: "the commonality of missionary and governmental interests created the basis for the persecutions against the Bwiti."

The Old Lie About Cannibalism, Weaponized

The persecution needed a justification, and the one already available had been circulating for decades: the claim that Bwiti initiation required a human sacrifice, ideally a child, whose flesh was then eaten alongside the iboga root. This accusation traces back to the same colonial-era fantasy machine that produced the broader myth of Fang cannibalism (documented in a separate article in this series). By the 1930s it had been repeated so often and so authoritatively by missionaries that, as Samorini notes, "even today the Fang Bwitists themselves consider it true." A Spiritan missionary named Joseph Coignard wrote in 1926: "The Bwiti is the father of the mongongo, of theft and of murder," explicitly naming one of the central musical instruments of the cult, the mongongo, as though the sound bow itself were criminal.

With that accusation as pretext, the attacks followed a consistent pattern. Missionaries organized raids, sometimes with converted native allies, sometimes directly alongside colonial gendarmes, usually timed to hit the Bwitist night vigils when communities were gathered. The attackers' war cry, recorded by Świderski from his own Gabonese informants, was "tigan éboga": eradicate iboga. People who could run, ran. The ones who were caught were tied by the neck, dragged to military posts, and whipped until they bled. Those who resisted were killed, hanged, or shot. Samorini records one further detail without softening it: "Often, in order to humiliate the Bwitists, the French soldiers raped their women before their eyes."

The Priest Who Later Said He Was Wrong

The best-documented single case is that of Jérôme Marie Mba Bekalé, a Fang Catholic priest, one of the first Gabonese men ordained to the priesthood (the seventh, in 1923). In May 1934, Jérôme Mba led an armed operation to systematically destroy Bwitist temples along the road from Libreville to Médouneu. His men entered the temples, smashed the sacred harps and ritual objects, and provoked confrontations with the initiates. In the village of Abogotom, the local Bwitist leader, Nguema Bibang, physically blocked Jérôme Mba from entering the temple and was shot dead with a rifle. The whole village turned on the raiding party, which had to be evacuated to the nearest military post under armed escort.

There was a court case. It went, unusually, in favor of the Bwitists: the court recognized their right to defend their temple and granted permission to rebuild it. Jérôme Mba was fined as civil compensation, a fine his superior paid for him, and he was reassigned to another mission. He did not stop. A 1943 letter he wrote to the apostolic vicar complains that he was attacked during a later visit to the same region, in apparent retaliation for having had a local Bwitist chief removed from his civil post and his temple ransacked the year before.

What makes this case more than a story about a fanatic is its ending. Świderski met Jérôme Mba shortly before the priest's death in 1970, decades after the campaign. According to Świderski's account, the priest expressed deep regret for the anti-Bwiti campaign he had led, explaining that "he had reacted on the basis of his education received in the seminary, without knowing the cultural and religious values of his fellow brothers, the Fang." A man spent his career destroying his own people's temples in the name of a seminary education that had taught him nothing about who they actually were, and said so himself, forty years later, to the one researcher who happened to ask.

Equatorial Guinea: Where It Got Worse

If the persecution in French Gabon was brutal, the campaign under Spanish colonial rule in Equatorial Guinea was, in Samorini's account, more sustained and more openly inquisitorial. The same core accusation was deployed, often in more lurid and specific form. A 1938 article, cited by Samorini under the pseudonymous byline "Un Continental," describes the alleged ritual in detail: "To enter the Embueti [Bwiti] one must sacrifice a human being, generally a son. Death is given very slowly by means of a drink that consumes it little by little, and they are so skilled in this and calculate the dose so well, that they know the month until the day on which he must die, which is generally between three and six months." The article goes on to claim the body was then smoked and eaten as part of initiation. No such case was ever substantiated in any court record Samorini could locate. A 1939 colonial government report, the trigger document for Equatorial Guinea's version of the crackdown, admitted outright that no cases of human sacrifice had actually been confirmed. It argued for repression anyway, citing concern over the "power of brainwashing" Bwitist leaders held over initiates, and recommended forced labor and, in the worst cases, hanging.

Archival trial records from the Fernando Poo colonial administration (the island now called Bioko) run from 1940 to 1951, with sentences of months to a full year in prison for offenses as vague as "dedicación de medicinas Bueti" (dedication to Bwiti medicines). A 1947 sentence condemned a man named Beernardo Ripen to a year in prison for being caught with "a book and medicinal objects" and for "practising and explaining the medicine of the country." Another 1947 case references a "book of medicine of the Boti [Bwiti]" seized from a Bwitist woman, a detail Samorini connects to his own fieldwork: in the 1990s, officiants of the Fang Ndea Kanga branch showed him a handwritten notebook filled with text and drawings, the kind of mnemonic training document apparently in continuous, if secret, use since at least the 1940s.

The worst single recorded incident came in 1948: seven bandzi, initiates, were hanged. Among the named martyrs from this period is a Fang officiant called Essindong, remembered as having been crucified on a flagpole, a detail Samorini sources to Świderski's 1990 history of the religion. In 1927, a Bwitist leader named Alfonso Mba was arrested; investigators found "bones, skulls, hands" in his possession and held him for two months at the Calatrava prison, where he was tortured in an effort to extract the names of other Bwitists. A contemporary account notes, with no apparent irony from the writer, that he may have revealed something under torture before he died, "leaving us who break his heads with the task of verifying the most secret part of the sect."

Colonial newspapers of the period called openly for the sect's elimination. One 1938 piece recommended simply shipping all Bwitists to the penal colony on Fernando Poo "for life," predicting that "we shall see how such an accursed sect will magically disappear." Another contributor, writing in 1946, laid out the choice facing the administration in strikingly cynical terms: "to accelerate the process of disintegration, introducing disturbing elements and fomenting internal dimensions, or to use the sect for certain colonial political purposes, effectively controlling the direction and orienting it towards predetermined objectives." Three years later a similarly anonymous writer repeated the same calculus almost word for word, arguing that the two real options were destruction or co-option, and that co-opting Bwiti could serve "magnificent results" for Spain's broader colonial strategy in the Gulf of Guinea.

What the Persecution Produced

Samorini's account does not end with the violence. It ends with what the Bwiti movement did in response, which turned out to reshape the religion permanently. The same two decades of persecution, the 1930s through the 1950s, produced a wave of internal reformers, Fang Bwitists who argued that the old skull-relic practices at the heart of the accusations should be abandoned entirely, and who began building what amounted to a new, more unified Bwiti identity partly in direct response to the campaign against them. One reform movement, Nganga Disumba, founded in 1942 after a woman named Efire Mintsa reported a vision of a vanished guiding star, explicitly worked to abolish the bone cult across Bwitist branches and to push for full social equality for women within the religion, a genuinely radical shift for a tradition that had been exclusively male for its non-syncretic forms. Another reformer, Ndong Obame Eya, convened representatives of twelve Fang clans with the stated aim of founding something close to a national Bwiti church.

The theology of these reform movements absorbed the trauma directly. Some prophets taught that the entire missionary project rested on a deeper, older betrayal: that Christ himself had been killed by white men specifically because they had discovered his plan to bring iboga to Africans. It is a striking inversion, turning the central story of the religion that had just spent two decades trying to destroy them into evidence of white guilt rather than white authority.

Bwiti did not disappear under this pressure, and it did not stay the same either. The documentary record Samorini assembled, court files in two colonial archives, missionary letters, newspaper columns calling openly for extermination by exile or worse, fieldwork notebooks still being shown to researchers sixty years later, describes a religion that survived a sustained, state-backed attempt to eliminate it by rebuilding itself around the very persecution it endured. Fang Bwitists today still name their martyrs. Nkogho Mba Ndzambiavanga, killed with a nail through his skull for attending a ceremony, is one of roughly a dozen names that have been carried forward by communities for whom this is not distant history but living memory, inherited the way any family inherits the names of people who did not survive something.
