Graded societies, esoteric governance, and masquerade traditions

ekpe:  https://ontology.irokosociety.org/iroko-ekpe# v2.0.0 Download TTL ↓ GitHub ↗

Domain module. Vocabulary for documenting initiatory societies, grade structures, esoteric governance, and sodality membership across Afro-Atlantic traditions. Covers Ékpè/Ngbe, Abakuá, Ogboni/Oshugbo, Oro, Gelede, Egungun, and analogous institutions. Distinct from iroko-ile (religious houses and lineages) and iroko-travay (ritual processes): this module focuses on the institutional architecture of sodalities as systems of graded authority, esoteric knowledge, and community governance. Use with iroko-authority to model grade conferral authority and recognition networks; iroko-epistemic to constrain disclosure of restricted grade content and member identities.

InitiatorySociety
Initiatory Society
Subclass of: Organization, SacredEntity

A sodality or secret society organized around graded initiation, with esoteric knowledge and authority distributed across hierarchical grades. Membership is earned through initiation rather than birth or lineage alone. Examples: Ékpè/Ngbe lodges (Ejagham, Cross River Nigeria/Cameroon), Abakuá potencias (Cuba), Ogboni chapters (Yorùbáland), Gelede societies (Yorùbá/Fon/Ewe), Egungun lineage associations. Subclasses schema:Organization for interoperability with external directories, and iroko:SacredEntity for access control. Distinguished from iroko:House (which organizes around founding-elder lineage) in that membership cross-cuts lineage boundaries.

MembershipRecord
Membership Record
Subclass of: SacredEntity

A record documenting an individual's initiation into and progression through a society. Membership records are among the most sensitive data in this framework: the identity of initiates is strictly guarded by all documented traditions, and their disclosure to outsiders is a serious breach. Default access is no-access; date and grade level may be community-restricted in contexts where historical record-keeping is an accepted practice (e.g., Cuban Abakuá records kept since the 19th century).

SocietyGrade
Society Grade
Subclass of: SacredEntity

A defined rank or level within an initiatory society's graded hierarchy. Each grade confers specific knowledge, privileges, obligations, and esoteric rights. Grade names, their sequence, and their content are among the most carefully protected knowledge in these traditions. The existence of a grade structure is public; grade names are community-restricted; grade content and sequence are initiated-only or initiated-elder.

SocietyLodge
Society Lodge
Subclass of: Initiatory Society

A local chapter or lodge of an initiatory society. Ékpè lodges in Cross River; Abakuá potencias in Havana and Matanzas; Ogboni chapters in Yorùbá towns. Each lodge may have its own territory, titleholders, and charter, while being part of a broader society network. Uses iroko:parentSociety to link to the overarching tradition-level society.

SocietyMasquerade
Society Masquerade
Subclass of: SacredEntity

A masked or costumed ritual embodiment associated with an initiatory society, representing an ancestor, force, or principle. Examples: Abakuá íremes (diablitos) representing the voice of the fish Tanze; Egungun masquerades embodying ancestral spirits; Gelede masquerades honoring the mothers. The masquerade as a cultural form (name, tradition, function) is community-restricted; the identities of performers and operational sequences are initiated-only. Distinct from iroko:SpiritualEntity (which covers the spiritual force) and travay:CeremonialSequence (which covers the ritual sequence).

SocietyTitle
Society Title
Subclass of: SacredEntity

A named office or titled position within an initiatory society, distinct from grade level. Titles may be elected, inherited, purchased, or conferred. Examples: Iyamba (Abakuá), Isue (Abakuá), Ekueñón (Abakuá), Apetebi Ogboni, Olori Egungun. Each title carries specific ritual functions, insignia, and governance authority. Title names are community-restricted; the ritual functions attached to them are initiated-only.

InitiatorySocietyTypeScheme

Abakuá
society-abakua

The Abakuá mutual aid and initiatory society founded in Cuba in 1836, derived from Ékpè/Ngbe through enslaved Efik and Efut practitioners in Havana and Matanzas. Organized into potencias (lodges), each with a specific founding charter and ranked titleholders. Known in Cuban public life through the íremes (diablito masquerades) which appear at funerals and public ceremonies. Male-only by tradition (juramento).

One of the most extensively documented Afro-Atlantic initiatory societies due to 19th-century Cuban court records and 20th-century ethnographic work (Cabrera, Sosa). Historical lodge names and early records are in the public domain; contemporary lodge governance and membership remain restricted.

Agemo
society-agemo

An Ijebu Yorùbá priestly and masquerade society associated with Agemo, a deity of transformation and mediation between worlds. The Agemo festival cycle involves multiple masquerades representing aspects of Agemo's power. Restricted primarily to Ijebu initiates.

Egungun
society-egungun

The Yorùbá ancestral masquerade society responsible for summoning and embodying ancestral spirits (egungun). Membership and performance rights are typically hereditary through specific lineages. The masked figure is understood as a manifestation of the collective ancestral force, not a theatrical performance. Widespread across Yorùbáland and diaspora.

Gelede
society-gelede

A masquerade society of the Yorùbá, Nago, and Fon peoples honoring the power of women, especially elder women, ancestresses, and the mothers (àwọn ìyá wa). Gelede festivals feature carved wooden masks worn by male dancers who embody female spiritual authority. UNESCO Intangible Cultural Heritage. Active in Nigeria, Benin, and diaspora communities.

Ogboni / Oshugbo
society-ogboni

The Yorùbá earth-deity society organized around Onilé (the earth) and its representations. Historically a governance institution with judicial, political, and ritual authority in Yorùbá towns. Members include both men and women. The Reformed Ogboni Fraternity (ROF) is a Christianized offshoot. Distinct from the traditional Oshugbo lineages in Ijebu and other areas.

Also known as: Reformed Ogboni Fraternity

Oro
society-oro

A Yorùbá male initiatory society associated with the voice of Oro (heard as a bullroarer), ancestral authority, and community sanction. Oro festivals enforce communal prohibitions and conduct ancestral rites. Strict gender separation is central to Oro practice: women must remain indoors when Oro goes out.

Other
society-other

Initiatory society type not covered by existing concepts. Use skos:scopeNote to describe.

Poro
society-poro

The male initiatory bush school society widespread among Mande, Kpelle, Temne, and neighboring peoples of Sierra Leone, Liberia, and Guinea. Poro manages male initiation, education, and community governance through a graded forest-based curriculum.

Sande / Bundo
society-sande

The female counterpart to Poro, managing female initiation among Mende, Temne, and neighboring peoples. Sande is distinctive in African contexts as a society where women wear and operate the sacred Sowei helmet mask.

Ékpè / Ngbe
society-ekpe

The Ékpè (also Ngbe) leopard society originating among Ejagham and neighboring Cross River peoples of Nigeria and Cameroon. One of the most widespread and influential initiatory societies in West Africa, with documented diaspora presence through enslaved Africans in Cuba (Abakuá) and elsewhere. Organized around graded leopard-force initiation; Nsibidi script is associated with Ékpè esoteric communication.

Also known as: Leopard Society

Ékpè and Abakuá are historically related but institutionally distinct. Use iroko:parentSociety to express the derived relationship.
