Origins and history
Yorùbá tradition holds that the group's ruling lineages, and by extension Yorùbá civilisation itself, descend from Odùduwà, a founding figure credited with establishing Ilé-Ifẹ̀ as a sacred capital; the city's artists were producing sophisticated bronze, stone, and terracotta sculpture by around the twelfth century, work now held in museums in Nigeria, Europe, and North America S1. Rather than forming a single kingdom, the early Yorùbá organised into numerous independent city-states — Ifẹ̀, Ọ̀yọ́, Ijẹ̀bú, Ẹ̀gbá, Ìjẹ̀ṣà, and others — each ruled by an ọba (king) claiming descent from Odùduwà's line, a structure that produced a shared culture without shared central government S1. Among these, the oyo empire rose from around the fourteenth century to become, from roughly 1650 to 1750, the dominant Yorùbá military and trading power, its expansion built on cavalry forces sustained through trans-Saharan horse trade and eventually bringing some thirteen rival territories under its authority S3. Oyo's collapse in the 1810s–1830s, driven by internal succession conflict, the 1817 Ilorin revolt, and pressure from the Fulani-led jihad that produced the neighbouring sokoto caliphate, fragmented Yorùbá political power and coincided with a surge in the number of Yorùbá captives sold into the transatlantic slave trade during the trade's final decades S3
Geographic distribution
The Yorùbá homeland covers south-western Nigeria — Lagos, Ogun, Oyo, Osun, Ondo, and Ekiti states — together with Yorùbá-speaking populations in Kwara and Kogi states further north, and extends across the Nigeria–Benin border into eastern Benin and northern Togo S1. Beyond this core, Yorùbá communities are established throughout Nigeria's major cities, particularly Lagos as a commercial capital, and among the descendants of enslaved and more recently emigrated Yorùbá in the Americas and Europe S1S2
Language
Yorùbá belongs to the Volta-Niger branch of the Niger-Congo family and is one of Nigeria's three major indigenous languages under national education policy, distinguished by its three-tone system and a Latin-based orthography first devised in the nineteenth century and revised several times since S1. Its classification, dialect variation, and speaker estimates are treated in full at yoruba language S1
Social and political organisation
Traditional Yorùbá society is built around the extended family under a bale (family head), with village and town governance organised hierarchically beneath an ọba, whose title varies by town — Aláàfin at Ọ̀yọ́, Ọ̀ọ̀ni at Ilé-Ifẹ̀, and other local titles elsewhere S1. At the height of Oyo's power, the ọba's authority was checked by the Ọ̀yọ́ Mèsì, a council of chiefs led by the Bashọrun, illustrating a broader Yorùbá pattern in which kingship operated alongside chiefly councils rather than as unconstrained monarchy S3. This city-state structure meant Yorùbá political history was never fully unified even at Oyo's peak, and rivalries among Yorùbá states, including the nineteenth-century Yoruba wars among Oyo's successor powers such as Ibadan and Abẹ́òkúta, remain a documented part of the group's internal history rather than a story of uniform political identity S3
Religion
Contemporary Yorùbá religious life includes Islam, Christianity, and Yorùbá indigenous religion (sometimes called Aborisha or Ifẹ́), and individual Yorùbá communities and even families frequently include adherents of more than one of these traditions S1. The indigenous system centres on Olódùmarè as a supreme creator and a large pantheon of òrìṣà (divinities) — commonly described as numbering in the low hundreds — associated with different domains of life and worshipped through divination, ritual, and festival S1. Reincarnation beliefs and ancestor veneration remain culturally significant even among Yorùbá who identify primarily as Muslim or Christian, reflecting the layered rather than mutually exclusive character of religious identity in the region S1
Culture and economy
Yorùbá visual arts — particularly bronze, terracotta, and ivory work associated with Ilé-Ifẹ̀ and Benin-influenced courts — are widely held in museum collections and remain a reference point for the group's artistic reputation S1. Yorùbá communities are also noted in demographic literature for an unusually high rate of twin births, and twins (ìbejì) hold a distinct ritual and social status in Yorùbá culture, including commemorative carved figures made when a twin dies in infancy S1. Historically an agricultural and trading economy centred on cocoa, kola nut, and textile production, Yorùbá economic life today is closely tied to Lagos and other south-western urban centres that function as Nigeria's commercial hubs S1
Population figures and the missing census
Nigeria has not collected ethnic data in a census since 1963, when the results were disputed along regional lines and parts of the country rejected the official figures; the 2006 national census again excluded ethnicity and religion from its questionnaire following years of ethnic and religious violence S4. Without an accepted count, published estimates for the Yorùbá population diverge: some place native speakers or ethnic Yorùbá at 40 million, other more recent tallies at 44–50 million, and a separate widely cited estimate puts the Yorùbá share of Nigeria's population at around 21% S1S5. As with figures for hausa people, igbo people, and fulani people, any single number should be read as an estimate tied to a specific source and year rather than an official statistic S4
Diaspora
The Yorùbá diaspora in the Americas originates in the transatlantic slave trade, which intensified after Oyo's collapse and carried large numbers of Yorùbá captives to Cuba, Brazil, Trinidad, and elsewhere from the late eighteenth through the nineteenth century S3S2. Enslaved Yorùbá and their descendants preserved elements of òrìṣà worship under conditions of slavery and religious suppression, giving rise to syncretic traditions including Cuban Santería (Lucumí), Brazilian Candomblé, and Trinidadian Orisha religion, each of which paired specific òrìṣà with Catholic saints — Ògún, the deity of iron and war, for example, became associated with Saint George in Rio de Janeiro and Saint Peter in Cuba S2. These diaspora traditions restructured religious practice in the process of transmission: priesthoods that in Yorùbá communities were often inherited by birth became initiation-based in the Americas, and separate òrìṣà cults that operated independently in Yorùbá towns were merged into single religious houses under the disruptive conditions of slavery S2
