Bioko Island in the context of Bight of Biafra

The Bubi people (also known as Bobe, Voove, Ewota and Bantu Bubi) are a Bantu ethnic group indigenous to Bioko Island, Equatorial Guinea. Once the majority group in the region, the population experienced a sharp decline due to war and disease during Portuguese expeditions. By the end of Spanish colonial rule in the mid 20th century, and after substantial intermarriage with newly introduced populations, such as Afro-Cubans, Krio people, Portuguese people and Spaniards, the Bubi people, again, experienced a great decline in number. Seventy-five percent perished due to tribal/clan rooted political genocide during a civil war that led to Spanish Guinea's independence from Spain. This, too, sparked mass exodus from their homeland with most of the exiles and refugees immigrating into Spain. The indigenous Bubi of Bioko Island have since co-existed with non-indigenous Krio Fernandinos; and members of the Fang ethnic group, who have immigrated in large numbers from Río Muni. Once numbering approximately 3 million, the Bubi currently number around 100,000 worldwide.

The Bubi people, both living in Equatorial Guinea and exiled abroad, have long held little political power and economic stake in their native land. However, appointed government officials, such as the former Prime Minister Miguel Abia Biteo Boricó and several other members of the current Equatorial Guinea government, are of ethnic Bubi descent.

The Bube language or Bubi, Bohobé, Bube–Benga or Etyö is a Bantu language spoken predominately by the Bubi, a Bantu people native to, and once the primary inhabitants of Bioko Island in Equatorial Guinea. The language was brought to Bioko from continental Africa more than three thousand years ago when the Bubi began settling on the island.

It has around 50,000 speakers, with three variants: North, South and Central-East. It is noted for its tonal character and the divergence of words by gender. The language is also spoken by the Bubi native to Gabon and Cameroon.
