The Bubi people (also known as Bobe, Voove, Ewota, and Bantu Bubi) are a Bantu ethnic group of Central Africa who are indigenous to Bioko Island, Equatorial Guinea. Once the majority group in the region, the population experienced a sharp decline due to disease and outright killing sprees 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 been outnumbered—first by non-indigenous Krio Fernandinos; and then by members of the Fang ethnic group, who have immigrated in large numbers from Río Muni. Once numbering over 3 million, the Bubi currently number less than 100,000 worldwide.
