Rules of Access, Stated Plainly

Becoming an egungun performer is restricted to initiated members of the specific egungun society responsible for a given masquerade, and Yoruba communities that maintain the tradition generally hold firmly that the identity of the person inside a given costume is not to be revealed, treated during the masquerade as genuinely secondary to the ancestral spirit understood to be present rather than as a performer in costume; this account accordingly describes that the tradition maintains this boundary rather than treating the identity behind any mask as something to be investigated or disclosed. Many egungun traditions also restrict certain roles, and in numerous communities the wearing of the masquerade itself, to men, and further restrict who may approach, touch, or in some traditions even look directly at an egungun once it has appeared, rules that egungun societies themselves enforce as part of maintaining the masquerade's standing as a genuine encounter with the ancestral dead rather than a public performance open to unrestricted engagement.

The tradition spread beyond Nigeria along the same transatlantic paths as other Yoruba derived religion, most notably taking root in Brazil, where communities associated with Candomble maintain their own related masquerade traditions descended from the same Yoruba root but developed under a different colonial and social history over several centuries. Access rules, permitted roles, and the specific internal organization of a given egungun society are set by that society and its elders rather than by any single, universal rule across all Yoruba communities.
